Best CAPTCHA Solvers in 2026: Full Comparison

The best CAPTCHA solver depends on your challenge mix and volume. As of September 2026, CapMonster Cloud has the cheapest reCAPTCHA v2 tokens ($0.60 per 1,000), CapSolver the cheapest Turnstile ($1.20), 2Captcha the widest type coverage, CaptchaAI the lowest cost at high, steady volume, and Anti-Captcha fully human solving for unusual formats. The IP you solve from quietly decides how many CAPTCHAs you see in the first place. Every price below is in US dollars from the vendor's own pricing page, checked on September 30, 2026. No vendor success-rate claims are repeated here, because none of them can be verified from outside.

AI vs Human CAPTCHA Solvers: What Actually Differs

Most of the market now calls itself an AI captcha solver, but the solving method still separates these services in three practical ways.

AI solvers run trained models against the challenge and return a token or answer in seconds. They are cheap and scale with concurrency, and they struggle only when a CAPTCHA vendor ships a new format the models have not seen yet. CapSolver, CapMonster Cloud and CaptchaAI all work this way.

Human solvers pay a worker to solve the CAPTCHA by hand. Anti-Captcha is fully human by design. Expect slower answers and higher prices, in exchange for coverage of odd, new or custom challenges that no model has been trained on.

Hybrid services try a model first and hand low-confidence tasks to a person to resolve CAPTCHA challenges the model is unsure about. 2Captcha runs this way, which is how it supports the longest type list in this comparison.

Can AI solve CAPTCHAs well? For most mainstream formats, yes. A USENIX Security 2023 study led by UC Irvine researchers timed 1,400 participants on deployed CAPTCHAs and compared them with bot results from earlier published attacks: the bots matched or beat human accuracy and were faster on almost every type. What AI cannot do is make a flagged session look clean, and that part comes down to the IP and browser, covered below.

The Best CAPTCHA Solving Services, Tool by Tool

2Captcha

2Captcha has the widest tool support in this comparison: many bots, scrapers and antidetect browsers list it as a built-in option, and rivals such as CaptchaAI emulate its API. Its price list covers more than forty challenge types, from reCAPTCHA, Turnstile and Arkose Labs through Amazon, DataDome, GeeTest and a long tail of regional formats. Official SDKs ship in eight languages.

Pricing is per solved CAPTCHA: $1 to $2.99 per 1,000 for reCAPTCHA v2, $1.45 for Turnstile, and $1.45 or $2.99 for reCAPTCHA v3 depending on the score you need. It accepts cards, PayPal, Alipay and crypto including BTC and USDT.

Choose it for maximum compatibility and rare challenge types. Speed is the trade-off: human fallback can stretch solve times under load, and high-score v3 tokens cost double.

CapSolver

CapSolver is a pure AI service built around speed on token-based challenges. Current rates are $0.80 per 1,000 for reCAPTCHA v2, $1.00 for v3, $1.20 for both Turnstile and Cloudflare Challenge, and $2.00 for AWS WAF. It also ships integrations for AI agent frameworks and an MCP server, alongside the usual Selenium, Playwright and Puppeteer guides.

It suits fast token solving on Cloudflare-protected and AWS-fronted targets, and our Cloudflare Turnstile guide explains where solver tokens alone stop working. Watch the price on reCAPTCHA v3 Enterprise, which jumps to $3.00 per 1,000, and expect newly released formats to lag until the models catch up.

CaptchaAI

Of the five, CaptchaAI is the only one that drops per-solve billing entirely. Plans are priced by concurrent threads, with unlimited solves per thread: $15 a month for 5 threads, $30 for 15, $90 for 50, $170 for 100, up to $300 for 200, and VIP plans up to 5,000 threads. Requests above your thread count are rejected with an ERROR_NO_SLOT_AVAILABLE error until a slot frees up.

Coverage spans reCAPTCHA v2, v3 and Enterprise, Turnstile, Cloudflare Challenge, GeeTest v3 and a large library of image CAPTCHAs. Migration is unusually easy: tools that support 2Captcha can point at CaptchaAI through its compatible API or emulator, without code changes. Extras include a Chrome extension and a 3-day trial activated through support, with PayPal subscriptions and crypto on request.

Pick it for high, steady solving volume where a fixed monthly bill beats per-solve pricing. You pay for threads whether you use them or not, so light or occasional workloads cost more here than on a per-solve service.

CapMonster Cloud

ZennoLab's AI solver posts the lowest reCAPTCHA token prices in this comparison on its price list: $0.60 per 1,000 for v2 tokens and $0.90 for v3, with Turnstile and Cloudflare Bot Challenge at $1.30. Proxy costs are folded into those prices, so proxyless tasks need no separate proxy bill. SDKs cover C#, Python, JS, Go and PHP, and extensions run in Chrome and Firefox.

Budget reCAPTCHA volume and ZennoPoster users get the most out of it. Its weak spots are a $0.10 test balance that is small for real evaluation and a Turnstile rate slightly above CapSolver's.

Anti-Captcha

Anti-Captcha has run since 2007 and is still 100% human-solved. Prices start at $0.50 to $0.70 per 1,000 image CAPTCHAs, $0.95 to $2 for reCAPTCHA v2, $2 for Turnstile, and $5 for reCAPTCHA Enterprise, with automatic discounts as daily volume grows. Its browser plugin covers Chrome, Firefox and Safari and is also marketed as an accessibility tool for visually impaired users.

Reach for it on new, custom or unusual challenges where models fail. Every solve waits on a person, though, and Enterprise tokens are the most expensive in this group.

Per-Solve vs Unlimited: Which Pricing Model Costs Less

The break-even is simple arithmetic. CaptchaAI's entry plan costs $15 a month. At per-solve rates, that same $15 buys:

• reCAPTCHA v2: 25,000 tokens on CapMonster Cloud, 18,750 on CapSolver, about 15,800 on Anti-Captcha, and 15,000 on 2Captcha at its lowest tier.
• Turnstile: 12,500 on CapSolver, about 11,500 on CapMonster Cloud, about 10,300 on 2Captcha, and 7,500 on Anti-Captcha.

Past roughly 7,500 to 25,000 solves a month, depending on the challenge mix, the flat plan costs less. Below that, pay per solve.

Throughput is the other half. Five threads solving continuously at an assumed 10 seconds per task (an illustrative figure, not a measured rate) could handle 43,200 solves a day. Monthly volume rarely limits a thread plan; peak concurrency does. Size threads to your busiest minute, not your monthly total.

Free CAPTCHA Solver Extensions

If you want the best CAPTCHA solver for human browsing rather than bots, a free extension usually covers it. Buster: Captcha Solver for Humans is a free, open-source extension that solves reCAPTCHA audio challenges with speech recognition, and nothing else. NopeCHA offers an AI extension with up to 100 free solves a day for personal or hobby use, and paid subscriptions with higher daily caps above it.

Neither is built for automation at volume. The best CAPTCHA solver extension for automated work is the one from your paid service, loaded into your antidetect or automation browser profile. 2Captcha, CapSolver, CaptchaAI, CapMonster Cloud and Anti-Captcha all ship one that works as an auto CAPTCHA solver in the background.

The Ultimate CAPTCHA Solving Kit: Mobile Proxy + Solver

Knowing how to solve a CAPTCHA through an API is the easy half of a scraping job. Whether a challenge appears at all, and whether the token survives submission, depends on the network layer.

Frequency comes first. reCAPTCHA v3 returns a score for every request without showing anything, and the site decides what a low score triggers. Google does not publish its signals, but a session from a heavily abused datacenter range is exactly what the score exists to catch. Our reCAPTCHA v3 score explainer covers what counts as a good score and why 0.5 is the usual cutoff. Turnstile's Managed mode works on the same principle, choosing between an invisible check and a checkbox based on the visitor's risk level. A clean carrier IP keeps more requests on the quiet path, and every challenge that never renders is a solve you do not pay for.

Consistency comes second. A proxyless task solves from the vendor's own IP, then your scraper submits the token from somewhere else. Sites can check that: Cloudflare's Siteverify endpoint accepts the visitor's IP alongside the token. Sending your own proxy with the task keeps the solve IP and the submit IP identical.

That makes the kit two parts: a dedicated mobile proxy for the session, and any solver from this list running proxy-bound tasks through it. A VoidMob dedicated proxy is one real 4G/5G device per customer on a consumer carrier connection, so its IPv4 address sits behind the carrier's CGNAT alongside ordinary subscribers instead of in a datacenter range. It keeps the same IP until you rotate it, which is what a proxy-bound solve needs. For high-volume scraping where each job is short-lived, a pay-per-GB proxy list set to Sticky does the same job, holding one exit IP while that device stays online.

The task below sends a sticky proxy list with a reCAPTCHA v2 job. For a dedicated device, use the host, port and login shown on its proxy page instead.

The same task fields work on Anti-Captcha and CapMonster Cloud, with two differences: Anti-Captcha requires userAgent, and CapMonster uses plain RecaptchaV2Task for both modes, going proxyless when the proxy fields are left out. CapSolver takes the proxy either as these separate fields or as one string such as http:ip:port:user:pass, under its own task type names. CaptchaAI takes it as proxy and proxytype parameters on its 2Captcha-style in.php API. Use a list with a login and password, not an IP-whitelist list: the solver connects from its own servers, and a whitelist of your addresses would refuse it.

Proxy-bound solving has two side effects. The solver loads the challenge through your proxy, so on a pay-per-GB list those loads draw from your GB balance, while dedicated device traffic is unmetered. And the vendor holds your list login while tasks run: regenerating the list's password when the job ends revokes it immediately and gives the list a new identity.

A clean IP will not remove a CAPTCHA that a form renders for every visitor. It lowers how often risk-based checks escalate, which is where most solver spend goes. Our mobile proxy CAPTCHA guide covers the proxy side in more depth.

FAQ

Choose the Solver, Then Clean the Session

No single CAPTCHA solver wins every job. 2Captcha covers the most challenge types; CapMonster Cloud and CapSolver have the lowest per-solve prices, on reCAPTCHA and Turnstile respectively; CaptchaAI wins once volume makes a flat bill cheaper; and Anti-Captcha handles what models cannot. Pick by your challenge mix and monthly volume, then fix the other half of the problem: run proxy-bound tasks through a clean mobile IP and submit tokens the moment they arrive, so fewer risk-based checks escalate to a paid solve.
