0.6.2-rc.2

THIS IS A GITHUB ONLY PRE-RELEASE

• Added Javascript (Unsafe) input method. Unlike other methods, this method does not try to emulate mouse movements and is thus detected by any competent CAPTCHA provider. However, it's a lot faster and still enough for most non-Enterprise variants.
• Updated Javascript input method to fix potential detection vectors
• Solving in backgrounded tabs now works again with either Javascript (Unsafe) input method or the --disable-background-timer-throttling launch option.
• Fixed hCaptcha language switcher
• Fixed inconsistent motion data for hCaptcha
• Added partial support for some hCaptcha private versions
• Added experimental support for hCaptcha Accessibility challenges (text); the Recognition API isn't fully ready yet and basically outputting garbage 100% of the time
• Fixed focus bug in TextCAPTCHA
• Experimental Safari support

0.6.1

Release highlights

Added

• Automation: The extension popup now shows current and recent jobs.
• Turnstile: Added support for "government mode" challenges served from challenges.fed.cloudflare.com.

Changed

• Automation: The nopecha key in manifest.json is now placed at the top.
• PerimeterX: Added support for more embedding strategies.

Fixed

• Popup: Fixed solve delay settings not updating as intended.
• Popup: Fixed icons and text in settings headlines not being centered.
• hCaptcha: Fixed Firefox support for production builds. Version 0.6.0 only partially fixed this and worked only for development builds.

0.6.0

Release highlights

This release improves undetectability, solving reliability, popup diagnostics, and browser compatibility across supported CAPTCHA types.

• Reworked automatic pointer movement and click timing with session-scoped movement profiles, configurable Mouse Speed (Slow, Medium, Fast), optional Mouse Visualization, smoother drag paths, bounded correction gestures, more consistent iframe targeting, and continuity between repeated actions.
• Improved hCaptcha solving reliability with better media handling, Firefox fixes, stale solve-status cleanup, canvas pointer continuity, and drag waypoint preservation.
• Improved PerimeterX press-and-hold challenges by detecting the active button more reliably, holding with profiled pointer motion, releasing on challenge state changes, and falling back safely when no state change is observed.
• Added Text CAPTCHA math expression mode. When enabled, the extension can evaluate arithmetic prompts such as 2 + 3 = ?, respects operator precedence and parentheses, and rejects ambiguous or non-integer results instead of guessing.
• Improved GeeTest, AWS WAF, Lemin, FunCAPTCHA, reCAPTCHA, and Turnstile handling with more robust click/drag behavior, safer challenge detection, better duplicate-solve guards, and browser-specific fallbacks.
• Added richer popup solve status: the popup can show active solve phases such as submitting, queued, solving, applying, complete, failed, timed out, or stale; it also tracks recent outcomes and pass rate without exposing job IDs.
• Improved account/status feedback with startup badge refresh, clearer badge states for invalid keys, no credits, expired keys, update-required responses, and transient server errors.
• Hardened settings handling that preserves important user settings such as API keys, disabled hosts, enabled state, and per-CAPTCHA solve preferences across version resets.
• Fixed popup and runtime stability issues, including malformed announcement data freezing the popup, disabled-host crashes on non-standard tab URLs, popup render loops and nested buttons, stale applying statuses, empty-credit refresh behavior, Firefox hook/XHR issues, and extension reloads interrupting an open popup.
• Fixed build and packaging issues that caused the extension to fail loading in Firefox.
• Various bug fixes and improvements across the extension.

0.5.6

Release highlights

• Improved handling of hCaptcha drag-drop and label-binary challenges.
• Improved hook method implementation for stealth.
• Added user-configurable input method settings (CDP or native events).
• Added user-configurable hook method settings.
• Various minor bug fixes and improvements.

0.5.5

Release highlights

• Fixed bounding-box precision for square aspect ratio hCaptcha challenges.
• Improved mouse action implementation for all CAPTCHAs (Chromium-only).
• Various minor bug fixes and improvements.

0.5.4

Release highlights

• Updated mouse actions into an undetectable implementation for hCaptcha, FunCAPTCHA, reCAPTCHA, and Cloudflare Turnstile (Chromium-only).
• Fixed language setting for reCAPTCHA, hCaptcha, and FunCAPTCHA to consistently request English challenges.
• Fixed hCaptcha solving delay settings to work as intended.
• Improved checkbox handling for hCaptcha to reduce rate-limiting issues.
• Improved detection of hCaptcha challenge ready state to avoid premature solving attempts.
• Improved bounding-box precision for hCaptcha challenges on small viewports (mobile and low-DPI).
• Updated the requested API endpoints to https://api.nopecha.com/v1/ per new API versioning scheme.
• Reduced console spam from frequent background-content messages.

0.5.3

Release highlights

• Added support for hCaptcha video challenges and improved click precision.

AI updates

Introducing online RL for browser agents

• Our AI learns autonomously from feedback using thousands of simulated browsers. Based on initial testing, we expect significant improvements in solving efficiency and accuracy. This capability is currently being evaluated on select CAPTCHAs and will be rolled out broadly in the coming weeks.

0.5.2

Release highlights

• Fixed coordinate rescaling for hCaptcha drag-and-drop on small viewports (mobile and low-DPI) for accurate placement.
• Fixed checkbox detection for Cloudflare Turnstile when rendered on Cloudflare interstitial pages.
• Improved bounding-box precision for Cloudflare Turnstile elements to reduce mislocalization.
• Hardened error handling and reduced overhead in reCAPTCHA flows.
• Updated GeeTest logic to restore functionality.

API updates

• The API documentation has been refreshed and reorganized. See the new API reference: https://nopecha.com/api-reference/
• Quick-start guides and code examples remain available (and are being updated) here: https://developers.nopecha.com/

0.5.1

Release highlights

• Update hCaptcha click/drag coordinates (a new coordinate system was introduced by hCaptcha shortly after our 0.5.0 release, which caused the extension to click/drag wrong locations)

0.5.0

Release highlights

• New AI model for hCaptcha
• New AI model for general computer use (solves any on-screen CAPTCHAs and puzzles), invite-only beta
• Cloudflare Turnstile compatibility fixes
• Performance optimizations
• Stability improvements

Rollout notes

• The new models are being deployed to our production servers. Access may be limited until the Chrome Web Store update is live (expected 2025-11-10).
• During this window, hCaptcha solving and the GUI agent may be intermittently unavailable or fall back to the previous model.
• If you’re in the invite-only beta, you’ll be whitelisted automatically as the rollout progresses.
