Comparison of CAPTCHA-solving services for parsing automation and routine tasks

Automatic CAPTCHA solving is now a standard part of data scraping, web-service testing, and other automation jobs. CAPTCHAs were built to block bots. For developers and scrapers, they are just one more barrier. Anti-CAPTCHA services remove that barrier by mixing algorithms (OCR, neural nets) with human solvers when pure automation fails. This piece runs a technical comparison of eight services: 2Captcha, SolveCaptcha, AZCaptcha, NoCaptchaAI, 9kw.eu, CapSola, EndCaptcha, and Cap.Guru.

2Captcha

2Captcha is one of the oldest and best-known CAPTCHA solvers, running for more than 10 years. It relies on a huge distributed pool of real people to solve almost any CAPTCHA type, pushing accuracy toward 100% with retries. In practice 2Captcha can handle nearly any CAPTCHA. The question is time.

• Supported types. Virtually everything, from simple text and images to Google reCAPTCHA (v2, Invisible, v3, Enterprise), hCaptcha, Arkose Labs FunCaptcha, GeeTest, rotation and puzzle CAPTCHAs (Yandex, VK, etc.). Think of it as a Swiss-army tool that even covers rare local formats.
• Speed. Simple graphic CAPTCHAs in about 5–15 seconds. Hard ones such as reCAPTCHA typically in 10–30 seconds, rarely above a minute. During peak hours you may see delays, though Google CAPTCHA often lands in 10–20 seconds. Heavy JS challenges like reCAPTCHA v2 average around 38–40 seconds.
• Accuracy. Close to 99% thanks to human input. For simple CAPTCHAs it often hits 100% because the same puzzle can be resent for free if the first answer is wrong.
• Pricing. About $0.5–$1 per 1k simple CAPTCHAs. Complex ones (reCAPTCHA v2/v3) up to around $2.99 per 1k. Dynamic rates pull in more workers during load spikes. Minimum deposit is $1.

Integration and features. Straightforward HTTP/JSON API and compatibility with common protocols. Browser extensions for Chrome and Firefox. SDKs for multiple languages. Users can earn by solving CAPTCHAs for others.

SolveCaptcha

SolveCaptcha  is a newer player (launched in 2024) with a hybrid model. AI attacks simple CAPTCHAs in 2–5 seconds; multi-step and stubborn tasks route to human operators. The pitch is simple: fast, powerful, accurate.

• Supported types. All mainstream formats: Google reCAPTCHA v2/v3 (Invisible, Enterprise), hCaptcha, Arkose Labs FunCaptcha, Cloudflare Turnstile, GeeTest, more. Coverage lines up with top competitors.
• Speed. Thanks to the hybrid flow, it’s among the faster options. Simple images in 2–5 seconds; multi-step sets like reCAPTCHA in about 10–20 seconds. Google reCAPTCHA v2 averages roughly 13 seconds, faster than 2Captcha in many runs.
• Accuracy. Claimed 95–99%. AI handles the easy stuff, humans backstop the hard parts.
• Pricing. Competitive. Simple images about $0.5 per 1k, reCAPTCHA v2 around $0.55 per 1k. Tougher types such as FunCaptcha can reach about $2.99 per 1k.

Integration. Response format compatible with 2Captcha, which makes migration painless. Clear docs, code samples, and a Chrome/Chromium extension that auto-fills answers.

AZCaptcha

AZCaptcha is a low-cost automated solver. It’s fully algorithmic (OCR + ML) with no human fallback, which keeps costs down and scaling straightforward. It targets popular formats and advertises around 95–98% accuracy.

• Supported types. Standard graphic CAPTCHAs, Google reCAPTCHA v2/v3 (including Invisible), hCaptcha, other common types. Focus stays on widespread challenges that OCR and ML can crack. Unique or exotic flows may fall out of scope.
• Speed. The service targets 99% uptime with flat access across plans, so queues are avoided as long as compute is available. In practice, seconds for simple cases and tens of seconds for reCAPTCHA.
• Accuracy. 95–98% on supported formats. About 95% for simple text. For complex cases such as reCAPTCHA, 90% and up. You pay only for solved CAPTCHAs; wrong answers do not drain credit.
• Pricing. Among the cheapest. Images at $0.4 per 1k. Complex types (reCAPTCHA v2/v3, Invisible, hCaptcha) at $1 per 1k. Unlimited plans start at $24.99 per month, with tiers up to $299.9 per month for higher concurrency (roughly 25–100 parallel tasks). No free trial.

Integration and support. API available plus a Chrome extension, though the plugin reviews are mixed, better stick to the API. Detailed docs, how-to videos, a demo account. Support via Telegram, Mon–Sat 8:00–18:00. PayPal and crypto payments.

NoCaptchaAI

NoCaptchaAI represents the AI-only wave. No human solvers. That brings speed and ultra-low unit cost. Focus is on visual challenges solvable by computer vision.

• Supported types. Vision-friendly formats: Google reCAPTCHA v2 (image variants included), hCaptcha, standard graphic tasks such as text images and object classification. reCAPTCHA v3 and other behavioral checks aren’t handled directly because the system targets images and audio.
• Speed. A single image lands in about 0.2–0.5 seconds. A full multi-step puzzle such as image selection in reCAPTCHA finishes within a few seconds. Very fast.
• Accuracy. Claimed up to 99.9%, real-world sits near 95–98%. AI shines on common cases; oddball or highly customized puzzles can fail altogether. Failed attempts are usually billed, since the system cannot know an answer is wrong without external feedback.
• Pricing. Extremely low. About $0.14 per 1k reCAPTCHA v2/hCaptcha requests. Roughly $0.16 per 1k OCR image solves. Example scale: around 90k recognitions per $1. No subscriptions, pure pay-as-you-go. Free tier offers about 6k CAPTCHAs per month.

Integration. Clean web API and browser add-ons such as a Firefox plugin. No queues, high parallelism. Fire off many requests at once if your infra can keep up.

9kw.eu

9kw.eu is a crowdsourced platform where users solve CAPTCHAs for each other. Some earn by typing; others spend earned credits on their own tasks. Since humans are in the loop, nearly any human-solvable CAPTCHA can be handled. Speed and quality swing with the crowd.

• Supported types. Anything a person can solve: standard text and image CAPTCHAs, Google reCAPTCHA v2, hCaptcha, FunCaptcha, and more. No hard type limits because jobs are simply passed to a volunteer solver.
• Speed. Highly variable. Simple tasks in 5–15 seconds, median under a minute. Heavy load or tricky flows may stretch into minutes. The points system rewards faster solvers, so easy jobs tend to go quickly. reCAPTCHA often takes 20–50 seconds or longer during peak.
• Accuracy. Human dependent. Simple text around 90–95% success, complex visuals bring more errors. Quality sits below professional human networks with strong QA. Wrong answers can be retried or disputed to protect credits.
• Pricing. Internal currency is credits. A typical CAPTCHA costs 10 credits. You can buy credits or earn them by solving. Direct purchase works out to roughly €3.75 per 1k, with discounts for active contributors down to about €1.25 per 1k.

Integration and tools. API, plugins for popular software such as JDownloader and OCR4all. A desktop 9kw Client can watch your clipboard or browser and auto-submit tasks. No browser extensions. The UI is spartan yet functional, with stats, a forum, and task priority settings.

CapSola

CapSola is a cloud CAPTCHA solver that grew on the Russian-language market. The draw is speed and accuracy at a stable price point. Unlike classic crowds, pricing is fixed and not tied to marketplace load. You pay only for successful solves. The team puts extra effort into CAPTCHAs popular on local platforms such as Yandex.

• Supported types. Focus on formats common in Runet. Yandex SmartCaptcha (click objects), puzzle CAPTCHAs, and standard text CAPTCHAs are supported.
• Speed. In the top tier at around 5–7 seconds per solve, type-dependent. Service continuity is a selling point. No rate auctions, no speed dips at peak. For Yandex SmartCaptcha, 5 seconds is strong and often feels native.
• Accuracy. About 90–95% on average. That’s solid for automated solving. CapSola uses neural nets and likely limited human confirmation to hit those numbers on SmartCaptcha, which is hard for straight OCR.
• Pricing. Fixed and very low. By type:

SmartCaptcha (click) - 5 RUB per 1k

Puzzle CAPTCHA - 3 RUB per 1k

Text CAPTCHA - 1 RUB per 1k

You pay only for successful solves. A free trial for newcomers exists. In $ terms, even the priciest Yandex format runs about $0.05 per 1k, which is near free.

Integration and support. API with familiar patterns and code samples. Partner and referral options for developers. Responsive support through tickets, site chat, and Telegram. Simple UI, detailed docs. Easy to start even if you are new.
EndCaptcha

EndCaptcha is a premium service aimed at enterprises that need service guarantees. It stands out with a formal SLA. The backend is hybrid: automation plus human solvers. The offer also includes a generous trial and refunds on errors.

• Service quality. The differentiator is guaranteed speed and reliability. Average solve time sits near 7 seconds. If the SLA isn’t met, clients receive a full refund. That insurance against slowness and errors makes EndCaptcha unusual in this space.
• Trial. New users get 10 days or 1k credits free. The trial is big enough to run a proper bake-off. Refunds apply if you dislike the service or for wrong answers. Low risk.
• Supported types. All modern hard CAPTCHAs: Google reCAPTCHA v2/v3, hCaptcha, Arkose FunCaptcha, more. If something is missing, it’s likely brand-new or very rare. The emphasis stays on broadly deployed defenses.
• Pricing. Pack-based. The entry pack is $11.99 for 3k solves, about $4 per 1k. That’s pricier than mass-market options, but the tag reflects premium SLA, infra, and support. The free 1k at the start softens the entry hit.

• Integration. No browser extensions. The assumption is API-first integration into enterprise systems. Full docs behind registration. Targeted at B2B, with hands-on support to tune flows.

  Cap.Guru

  Cap.Guru (Captcha.Guru) is another AI-first solver. The mission: faster than a human, more accurate than professional typers. It competes head-to-head with NoCaptchaAI, aiming for speed and low cost without human fallback.

• Supported types. Google reCAPTCHA v2/v3 (Invisible), GeeTest sliders, and a few specific checks such as Binance and AWS CAPTCHAs. hCaptcha and Cloudflare Turnstile are not supported yet. Standard image CAPTCHAs, both text and graphic, are handled well.
• Speed. Extremely fast, similar to NoCaptchaAI. Most tasks are solved in seconds. Instant when a single step is enough. Practical throughput is limited by API caps and your compute; high parallelism is normal.
• Accuracy. Claimed to beat human pools on supported formats. For common reCAPTCHA and GeeTest, internal stats show around 99% success. AI still fails on corner cases. There is no human handoff, so errors are not corrected server-side, and you will need to resend. No refunds for failed solves, which is stated up front.
• Pricing. Very low and fixed:

• $0.55 per 1k reCAPTCHA v2/v3 tokens

• $0.50 per 1k GeeTest

• $0.1 per 1k standard image CAPTCHAs

• $0.1 per 1k AWS (Amazon WAF)

• $0.2 per 1k Binance

• 
  These numbers are striking. For example, 1k Google CAPTCHAs for about $0.55, while 2Captcha often runs $2–3. No subscriptions, pay-as-you-go. No free trial, though the sums to try are tiny.
  
   
• Integration. API with examples. Request and response patterns feel familiar to 2Captcha users, easing switch-overs. One price for everyone. Referral program for passive income if you bring clients.
   

Side-by-side summary without a table

Conclusions

Every service shines in a different lane.

• Fastest and cheapest. NoCaptchaAI and Cap.Guru cut latency to seconds and price to cents per 1k. Perfect when you chew through huge volumes of common formats such as Google reCAPTCHA and you want tiny budgets. Limits appear when a site ships something quirky or brand-new. AI may stall.
• Breadth and reliability. 2Captcha and hybrid peers such as SolveCaptcha can handle almost anything because humans are in the loop. Accuracy hovers near 99%. This is the flexible pick when site defenses keep changing.
• Balance. SolveCaptcha hits a useful middle ground. AI gets you speed, humans keep coverage. For B2B work where speed and success rates both matter, this hybrid feels right. Unlimited plans can make sense at steady high volumes.
• Local formats. If your targets live in the Russian-language web, CapSola is hard to beat. It cracks Yandex SmartCaptcha and puzzle flows quickly, at near-symbolic RUB pricing. The tradeoff is scope. Global CAPTCHAs such as reCAPTCHA are not the main focus.
• Enterprise guarantees. When stability is money, EndCaptcha stands alone. SLA with compensation, priority support, predictable speed near 7 seconds. You pay more, you get insurance. Ticketing rushes, mass drop sales, critical workflows, that kind of scene.
• DIY and backup. 9kw.eu fits tinkerers who don’t mind working for credits. It can also act as a fallback channel if your main vendor hits a snag. Don’t expect polished UX or consistent speed. Do expect flexibility.
  
   

Pro tip. Many seasoned teams chain providers. Try an AI-first pass with NoCaptchaAI or Cap.Guru. If it fails, fall back to a hybrid like SolveCaptcha. On timeout, ship to 2Captcha. Because APIs often align, routing can be automated. That stack gets you speed, coverage, and sane costs.

Pick for your use case. List the CAPTCHA types you face, throughput and latency targets, and budget. Maybe you run two or three in parallel. A small bake-off on your real data pays off fast, as free credits and low entry packs are common. Then lock in the routing logic and move on with fewer blockers.
