SideShift Alternatives: Instant Crypto Exchanges Compared in 2026

TL;DR

• Best SideShift alternative for most swaps: ChangeNOW. This Crypto Super App covers 1000+ assets and 1,000,000+ pairs, shows one all-in rate before you send, has no upper limit on swaps, and supports 200 countries. Registration is not required for a regular swap.
• Where ChangeNOW leads: cost transparency, availability, published limits, and public ratings (Trustpilot 4.6, Google Play 4.6, App Store 4.8).
• Where others win: SimpleSwap’s asset count (independent reviews put it as high as 2,800+), FixedFloat’s Lightning Network support and $1 minimum, and Changelly’s published 0.25% floating-rate fee.
• The catch: ChangeNOW doesn’t publish a percentage for its swaps, so compare the quote for your exact swap. Figures for the other four services come from independent reviews.

A broader look at SideShift alternatives is available on changenow.io, where instant-swap services are compared by exchange flow, asset support, custody considerations, and ease of use.

SideShift is one of several instant exchange services that swap one coin for another without an account. This guide compares it with ChangeNOW, FixedFloat, SimpleSwap, and Changelly on the same criteria, so you can see where each one is stronger, whether you want to swap into Bitcoin (BTC, “digital gold”), Ether (ETH), Tether (USDT, “stables”), or Litecoin (LTC). Figures for ChangeNOW are the company’s own. Figures for the other four come from independent reviews and public help pages, and may differ from what their websites show today. All data was checked on 30 October 2026.

Scores

Each service is scored from 1 to 5 on seven criteria, and the total is the weighted sum (method explained in the next section).

Criterion	Weight	ChangeNOW	SideShift	FixedFloat	SimpleSwap	Changelly
Rates and cost transparency	25%	5	3	4	3	4
Assets and pairs	20%	5	3	2	5	5
Speed	15%	4	4	4	3	3
Limits	10%	4	3	4	3	3
Custody and account	10%	5	5	5	5	4
Availability	10%	5	3	3	3	2
Support and trust	10%	4	3	3	3	4
Total	100%	4.65	3.35	3.50	3.60	3.75

Why each service scored as it did

• ChangeNOW: One all-in rate shown before you send, 1000+ assets, published limits, 200 countries, and public ratings. Held back on speed and support, where the figures are strong but not clearly ahead.
• SideShift: No account needed and non-custodial, but the fee is a margin inside the rate with no published schedule, the asset list is smaller, and no public ratings were found.
• FixedFloat: Explicit published fees (1% fixed, 0.5% floating) and Lightning Network support, held back by a smaller asset list and by security incidents in 2024 that an independent review reports, followed by a relaunch.
• SimpleSwap: The largest asset list in the comparison by some reviews, held back because fees are embedded in the rate without a breakdown and limits and ratings weren’t found.
• Changelly: A published 0.25% floating-rate fee, 1,000+ assets, and 24/7 support, held back by a broad list of restricted countries and by limited fee detail on fixed rates.

How We Compared: Our Methodology

All five services are scored on the same seven criteria, using the same 1 to 5 scale. The scores are combined into a weighted total, and the criteria that matter most to someone swapping crypto count the most. All data was checked on 30 October 2026.

Criterion	Weight	What we check
Rates and cost transparency	25%	Whether the all-in rate is shown before you send, fixed and floating options, how network fees are shown
Assets and pairs	20%	Coins and networks available, number of pairs
Speed	15%	Time from deposit to coins in your wallet
Limits	10%	Minimums, maximums, and whether they are published
Custody and account	10%	Whether funds are held, and whether an account is required
Availability	10%	Countries covered and restrictions
Support and trust	10%	Support hours, ratings, published company details

Rules.

• Sources. ChangeNOW’s figures are the company’s own. For the other four services, we use independent reviews and public help pages, and we say so. Where reviews disagree, we show a range instead of picking one number.
• Missing figures. If a figure wasn’t published on the pages we checked, we say so and score that item neutrally (3) instead of inventing a number or scoring it low.
• Risk checks. All five services use automated risk checks that can hold a transaction, so we don’t score them.
• Formula. Each score comes with a short note, and the total is each score multiplied by its weight, added up, and expressed out of 5.

Disclosure. ChangeNOW is one of the five services compared, and the one we recommend for most swaps. Its figures come from the company itself, which is a different level of evidence from the independent reviews used for the others, so treat the gaps between totals with that in mind.

The Four Alternatives in Brief

SideShift

SideShift swaps coins directly between wallets, with no account for a basic swap. Independent reviews describe it as non-custodial, supporting 200+ coins on 45+ networks (some say 300+), with no fiat support.

• Rates. You choose a variable rate, which updates until your deposit arrives and then locks in, or a fixed rate held for 15 minutes. With a fixed rate you must send exactly the amount you set, or the deposit is rejected and refunded.
• Fees. Reviews put its margin at about 0.5% to 1%, built into the rate. Network fees are shown separately on variable orders and included in the rate on fixed ones. No fee schedule with exact percentages is published.
• Limits. The deposit range varies by asset and is shown on the order page. SideShift’s help page says variable-rate swaps have no amount restrictions, but a deposit outside the range may be rejected.
• How ChangeNOW compares. ChangeNOW shows one all-in rate before you send, covers more assets, and publishes a clear limit: swaps start from about $2 and have no upper limit.

FixedFloat

FixedFloat is a non-custodial swap service that has run since 2018 and is known for Bitcoin Lightning Network support. Reviews list 60 to 100+ coins, and one review says it holds an Estonian FIU licence.

• Rates and fees. Its help page publishes two modes: a fixed rate at 1% plus a network fee, locked for 10 minutes, and a floating rate at 0.5% plus a network fee. If the market moves more than 1.2% before your transaction appears on the network, you are asked to accept a refund or continue at the market rate.
• Limits. Independent reviews cite a $1 minimum, the lowest of the five.
• Watch out for. The asset list is the smallest here, and one independent review reports security incidents in 2024 followed by a relaunch.
• How ChangeNOW compares. ChangeNOW offers many more assets and a single all-in rate. FixedFloat is the better fit if you specifically want Lightning swaps or a very small minimum.

SimpleSwap

SimpleSwap works as an aggregator, routing swaps through 20+ liquidity providers, and needs no account for most crypto-to-crypto swaps. Reviews put its asset count between 1,000 and 2,800+, the widest in this comparison, with fixed and floating rates.

• Fees. The fee sits inside the quoted rate as a spread. One review puts typical spreads at 0.5% to 2%, wider on fixed rates, with no separate breakdown.
• Speed. Reviews report typical swap times of 5 to 30 minutes.
• Extras. A loyalty program pays cashback of up to 0.4%, and fiat purchases run through partner providers, with one review noting a high card fee.
• How ChangeNOW compares. Its asset coverage is comparable, and ChangeNOW’s average swap time is about a minute. If you want the largest possible coin list or SimpleSwap’s loyalty program, check it first.

Changelly

Changelly has run since 2015 and lists 1,000+ assets with fixed and floating rates. Standard swaps need no account, and support runs around the clock through live chat and email.

• Fees. A floating-rate swap carries a 0.25% fee, built into the rate, which is the lowest published percentage of the five. Fixed rates include a premium, locked for 15 to 20 minutes, and network fees come on top.
• Speed. Reviews report typical times of 5 to 30 minutes.
• Fiat. Card purchases run through third-party providers and start from about 3.95% according to reviews.
• Watch out for. Reviews describe a broad list of restricted countries and say it is not available to US users.
• How ChangeNOW compares. ChangeNOW supports 200 countries and shows one all-in rate for both rate types. Changelly is the better fit if the published 0.25% floating fee matters most to you.

ChangeNOW in Brief

Since 2017, ChangeNOW has grown from an instant swap service into a Crypto Super App that more than 10 million satisfied clients use to exchange and buy crypto. It reports 50,000+ exchanges per day and 5,000+ API partners, supports 200 countries, and is run by CHN Group LLC, registered in Saint Vincent and the Grenadines.

• Assets. 1000+ across 110 blockchains, with more than 1,000,000 exchange pairs.
• Three steps. Choose the currency, make the deposit to the generated address, and receive the exchanged crypto. Registration is not required for a regular swap.
• Rates. A fixed rate completes the swap at the agreed amount regardless of market moves. A floating rate follows the market.
• Cost. No hidden fees: all costs are built into the rate shown upfront, with no additional charges after the swap.
• Quote quality. 98% of swaps are completed at a better rate than estimated or within 0.5% of it.
• Limits and speed. Swaps start from about $2 and have no upper limit. The average swap takes about a minute, and the result usually arrives within an hour.
• Extras. Cashback from 0.1% per swap, card purchases with 40+ fiat currencies through partner providers, and 24/7 support with a 3-minute response time.
• Ratings. 4.6 on Trustpilot (13,000+ reviews), 4.6 on Google Play, and 4.8 on the App Store.

Swaps can’t be cancelled once you’ve sent the funds, so check the address, the network, and the amount first.

Head-to-Head by Criterion

Rates and cost transparency (25%)

ChangeNOW 5, FixedFloat 4, Changelly 4, SideShift 3, SimpleSwap 3. Verdict: ChangeNOW.

ChangeNOW builds all costs into one rate shown before you send, whatever the rate type. FixedFloat and Changelly earn a 4 because they publish clear percentages: 1% fixed and 0.5% floating for FixedFloat, and 0.25% on floating rates for Changelly, in both cases with network fees on top. SideShift and SimpleSwap keep their margin inside the rate without a published schedule, so the cost is only visible in the quote.

Two caveats. ChangeNOW doesn’t publish a percentage for its swaps, so this is a comparison of how costs are presented, not of which service is cheapest, and the reliable way to compare is to enter the same swap into each service and look at the amount you would receive. We also did not find a published lock period for ChangeNOW’s fixed rate in the standard flow, while the others state 10 to 20 minutes.

Assets and pairs (20%)

ChangeNOW 5, SimpleSwap 5, Changelly 5, SideShift 3, FixedFloat 2. Verdict: a three-way lead.

ChangeNOW (1000+ assets, 1,000,000+ pairs), SimpleSwap (1,000+ to 2,800+ depending on the review), and Changelly (1,000+) are in the top tier. If SimpleSwap’s higher figures are right, it has the longest list, so check it first if you need an unusual coin. SideShift (200+ to 300+) and FixedFloat (60 to 100+) are noticeably smaller.

Speed (15%)

ChangeNOW 4, SideShift 4, FixedFloat 4, SimpleSwap 3, Changelly 3. Verdict: a three-way lead.

ChangeNOW averages about a minute, and one review puts SideShift’s median settlement at around 44 seconds. FixedFloat settles Lightning Network swaps in seconds, while on-chain swaps follow the network. SimpleSwap and Changelly are reported at typically 5 to 30 minutes. On every service the blockchain’s own confirmation times set the pace.

Limits (10%)

ChangeNOW 4, FixedFloat 4, SideShift 3, SimpleSwap 3, Changelly 3. Verdict: ChangeNOW and FixedFloat.

ChangeNOW publishes a clear range: swaps from about $2 with no upper limit. FixedFloat is reported with a $1 minimum, the lowest of the five. SideShift shows a deposit range per asset on the order page, and we didn’t find published limits for SimpleSwap or Changelly.

Custody and account (10%)

ChangeNOW 5, SideShift 5, FixedFloat 5, SimpleSwap 5, Changelly 4. Verdict: a four-way tie.

All five describe non-custodial swaps that need no account for a standard swap. Changelly scores one point lower because one review calls its flow semi-custodial, since you send crypto first, and it also runs a separate custodial exchange called Changelly Pro.

Availability (10%)

ChangeNOW 5, SideShift 3, FixedFloat 3, SimpleSwap 3, Changelly 2. Verdict: ChangeNOW.

ChangeNOW supports 200 countries. We found no country counts for SideShift, FixedFloat, or SimpleSwap, so they are scored neutrally, though SideShift checks access before use. Reviews describe a broad list of restricted countries for Changelly and say it is not available to US users.

Support and trust (10%)

ChangeNOW 4, Changelly 4, SideShift 3, FixedFloat 3, SimpleSwap 3. Verdict: ChangeNOW and Changelly.

ChangeNOW publishes a 3-minute response time and public ratings from three sources. Changelly has run since 2015 and scores 4.2 out of 5 from 156 reviews on Swapzone, with 24/7 live chat and email. FixedFloat scores 3.7 out of 5 from 91 reviews on Swapzone, and an independent review reports security incidents in 2024. We found no public ratings for SideShift or SimpleSwap. We did not verify licence details for any of the five.

The scoreboard

Result	Criteria	Weight
ChangeNOW alone in front	Rates and cost transparency, availability	35%
ChangeNOW tied for the lead	Assets and pairs, speed, limits, custody and account, support and trust	65%

ChangeNOW leads or shares the lead on every criterion, which gives it a total of 4.65 against 3.35 to 3.75 for the others. It doesn’t win outright on assets, where SimpleSwap and Changelly match it, or on speed, where SideShift and FixedFloat match it. Its lead comes from being at the top on every criterion, not from being far ahead on one.

Which One Should You Choose?

The right service depends less on a headline fee than on which coin you need, how much you are swapping, and what matters more to you: a published fee or one all-in rate.

• You want one all-in rate, published limits, and support in 200 countries: choose ChangeNOW. All costs are built into the rate shown before you send, swaps start from about $2 and have no upper limit, and its ratings are public (Trustpilot 4.6, Google Play 4.6, App Store 4.8).
• You need the longest possible coin list: check SimpleSwap first. Reviews put its list at 1,000 to 2,800+, and ChangeNOW (1000+) and Changelly (1,000+) are close behind.
• You want Lightning Network swaps or a very small minimum: choose FixedFloat. It supports Bitcoin over Lightning and is reported with a $1 minimum.
• You want the lowest published fee on a floating rate: check Changelly. It lists 0.25%, but reviews describe a broad list of restricted countries and say it is not available to US users.
• You want a fixed rate with a stated lock period: FixedFloat locks it for 10 minutes, SideShift for 15, and Changelly for 15 to 20. ChangeNOW also offers a fixed rate, and we didn’t find a lock period for its standard flow.
• You are moving a large amount: ChangeNOW publishes no upper limit on swaps. For the others, check the deposit range on the order page before you send.
• You want to know who is behind the service and what users say: ChangeNOW publishes its operating company, response time, and ratings from three sources. We found no public ratings for SideShift or SimpleSwap.

A few rules of thumb. Enter the same swap into each service and compare the amount you would receive, since that includes every fee and is more reliable than comparing percentages. Double-check the address and the network before you send, because blockchain transactions can’t be reversed. With a fixed rate, send the exact amount you set. Send a small test amount first if you are new to swapping. And check your local tax and reporting rules, because swapping crypto can create record-keeping duties.

Frequently Asked Questions

Is ChangeNOW a good SideShift alternative?

For most swaps, yes. ChangeNOW covers 1000+ assets against SideShift’s 200+ to 300+, shows one all-in rate before you send, publishes clear limits, and supports 200 countries. SideShift is a fair choice if you prefer a service that has focused on account-free swaps since 2019.

Do I need an account to use ChangeNOW?

Not for a regular swap. You choose the pair, make the deposit to the generated address, and receive the exchanged crypto. Account-free is not the same as check-free, though: additional checks can apply in some cases. Independent reviews describe the other four services as account-free for standard swaps, with automated risk checks that can hold a transaction.

How much does each service charge?

Published percentages: FixedFloat charges 1% on fixed rates and 0.5% on floating rates, plus network fees, and Changelly lists 0.25% on floating rates, with fixed rates including a premium. SideShift’s margin is reported at about 0.5% to 1% inside the rate, and SimpleSwap’s is a spread inside the quote. ChangeNOW builds all costs into the rate shown upfront, with no additional charges after the swap, and doesn’t publish a percentage, so enter the same swap into each service to compare.

What is the difference between a fixed and a floating rate?

With a fixed rate, the swap completes at the agreed amount regardless of market moves. With a floating rate, the final amount follows the market until your deposit is confirmed, so you may receive a bit more or less than quoted. ChangeNOW, FixedFloat, SideShift, SimpleSwap, and Changelly all offer both.

Which service is fastest?

ChangeNOW averages about a minute, and the result usually arrives within an hour. One review reports a median of about 44 seconds for SideShift, and FixedFloat settles Lightning swaps in seconds. SimpleSwap and Changelly are reported at typically 5 to 30 minutes. Blockchain confirmation times set the pace on every service.

Can I cancel a swap after I send the funds?

No. Once you have sent the funds, the swap can’t be cancelled, so check the address, the network, and the amount before you send. If something goes wrong, such as crypto sent to the wrong network, ChangeNOW’s support team is available 24/7 and handles complex cases like this, with a response time of 3 minutes.

Which service has the most coins?

By reviews, SimpleSwap (1,000 to 2,800+), followed by ChangeNOW (1000+ assets and 1,000,000+ pairs) and Changelly (1,000+). SideShift lists 200+ to 300+ and FixedFloat 60 to 100+.

Do I need to think about taxes?

Yes. Swapping Bitcoin (BTC), Ether (ETH), Tether (USDT), Litecoin (LTC), or other coins can create record-keeping and reporting duties, and the rules differ by country. Keep a record of every swap with its date, amount, and the value in your local currency at that time, and ask a local accountant how your country treats crypto.

Choosing an Instant Exchange by What You Need Most

Each of these services suits a slightly different priority. FixedFloat is built around Lightning and small amounts, Changelly around a low published floating fee, SimpleSwap around the widest coin list, and SideShift around account-free swaps with a fixed rate that holds for 15 minutes.

ChangeNOW is the one that doesn’t fall behind on any criterion. It offers 1000+ assets, one all-in rate shown before you send, an average swap of about a minute, no upper limit, 200 supported countries, and public ratings, plus a card flow with 40+ fiat currencies. For most swaps, that makes it the stronger choice, and for anyone who wants a single service they can rely on for any pair, it is the shorter route to the coin they actually want. Pick the priority that matters most to you first, then compare the exact quote.
