Capsolver: Captcha Solving Service

Capsolver is a captcha solving service built on AI and machine learning. It covers most of the challenge types you'll hit in production, integrates through a simple API, and prices per solve rather than per seat.

What it solves

• reCAPTCHA — v2, v3 and Enterprise
• hCaptcha — normal and Enterprise
• FunCaptcha — the game-style challenge
• GeeTest — V3 and V4
• DataDome — bot management across sites, APIs and mobile apps
• Cloudflare — Turnstile and the interstitial challenge
• Imperva / Incapsula
• Akamai — web and BMP
• AWS WAF captcha
• CyberSiara
• ImageToText — plain image captchas turned into text

Pricing models

Pay per usage. You're billed per request. Nothing up front, which suits variable or seasonal workloads.

Packages. Bulk pricing for steady volume, up to around 60% cheaper than paying per request.

Custom instances. For specific captcha types — reCAPTCHA, hCaptcha, FunCaptcha, GeeTest, DataDome — with a request allowance on a 30-day renewal. Worth it once you know exactly which challenge dominates your traffic.

Check their pricing docs for current numbers.

Where people use it

Anywhere a challenge sits between an automated job and the data it needs: price monitoring, ad verification, account workflows, form automation, and document or image digitisation through the ImageToText endpoint.

What makes it worth a look

It's flexible — you can start with a small top-up rather than a contract, and scale to a dedicated instance if your volume justifies it. Reliability is the other half: around 100 million requests a month at 99.9% uptime, with clients across more than 100 companies. Integration is documented for 300+ platforms, so in most stacks it's configuration rather than code.

They also run a referral programme paying up to 10% of what your referrals top up, and a developer programme paying 5–20% on usage from your users.

Pair it with the right proxies

A solver deals with challenges after they appear. Proxies decide how often they appear at all. Run a solver behind a dirty datacenter pool and you'll pay for a solve on nearly every request; run it behind clean residential IPs with sensible pacing and most requests never get challenged, so the solver only handles the hard tail.

That's the split worth engineering around: proxies for the volume, a solver for the exceptions. Both bills stay small.
