CapSolver is an AI-powered automatic CAPTCHA solving service with a REST API and SDKs for web scraping, data extraction, and browser automation workflows.
About
CapSolver is an AI-based service that automatically solves CAPTCHA challenges such as reCAPTCHA v2 and v3, Cloudflare Turnstile, Cloudflare Challenge, AWS WAF, DataDome, GeeTest, and image-to-text puzzles. It is aimed at developers and teams whose web scraping, data extraction, and automation workflows are interrupted by bot-detection challenges, and it returns verified tokens or solutions that can be inserted into browser sessions or HTTP requests.
The platform operates as a task-based REST API: an application submits a CAPTCHA task with the createTask endpoint, retrieves the result with getTaskResult, and injects the returned token into its own request flow. First-party SDKs are available for Python, JavaScript, Go, and PHP, and proxy configuration (including residential IP rotation) can be set per task. Beyond the API, CapSolver offers a browser extension for Chrome and Firefox plus integrations with Selenium, Playwright, Puppeteer, n8n, and AI agent frameworks. The vendor also publishes guides and a compliance and privacy hub describing its stance on responsible use.
