CAPTCHA Solver Type Coverage Matrix

Choosing a solver means knowing whether it actually handles the CAPTCHA type you're targeting. This matrix maps every major CAPTCHA type against every major solver. Coverage gaps are where integrations silently fail.

For ranked comparisons, see Best CAPTCHA Solvers. For a deep dive on a specific type, see the per-type guides linked in each section.

Coverage Matrix

✅ = Fully supported with dedicated task type
⚠️ = Supported with limitations (noted below)
❌ = Not supported

Coverage Score Summary

Limitation Notes

reCAPTCHA v3

• DeathByCaptcha ⚠️: Supports v3 but does not offer min_score configuration — score outcomes are unpredictable.

reCAPTCHA Enterprise

• NopeCHA ⚠️: Enterprise available via browser-extension mode only; no direct API task type.
• DeathByCaptcha ❌: No Enterprise endpoint support as of latest data.

hCaptcha Enterprise

• 2Captcha, CapMonster, Anti-Captcha, NextCaptcha ⚠️: Standard hCaptcha API used; no dedicated Enterprise task type with rqdata support. Pass rates on Enterprise targets are lower.

Cloudflare Managed Challenge

• CaptchaAI ⚠️: Supported via headless browser mode (slower, higher cost).
• NopeCHA ⚠️: Supported via browser-extension integration only.
• All others ❌: Only Turnstile widget is supported, not the full-page interstitial.

GeeTest v4

• CapMonster ⚠️: v4 task type exists but solve rates are significantly lower than v3 (~74% vs 93%).

FunCaptcha / Arkose Labs

• NopeCHA ⚠️: FunCaptcha support exists but is unreliable at high volumes.
• DeathByCaptcha ❌: No FunCaptcha support.

API Method Reference

The API method/task type name differs per solver:

Choosing Based on Coverage

Solve only reCAPTCHA v2/v3 and hCaptcha: Any solver works — pick on price (CapMonster) or solve rate (CaptchaAI).

Solve reCAPTCHA Enterprise: CaptchaAI, CapSolver, 2Captcha, Anti-Captcha — all fully supported.

Solve GeeTest v4: CaptchaAI, CapSolver, 2Captcha, Anti-Captcha — avoid CapMonster for v4.

Solve Cloudflare Managed Challenge: CapSolver first choice; CaptchaAI as fallback with headless mode.

Broadest type coverage with single API key: CaptchaAI (16/16 types, full 2Captcha API compatibility).

Production Readiness Notes

Use CAPTCHA Solver Type Coverage Matrix as a decision and implementation aid, not just as a one-time reference. The practical test for captcha solver type coverage is whether the same approach behaves reliably when traffic is messy: rotating sessions, expired tokens, changing widget parameters, intermittent solver delays, and target pages that refresh without warning. For Developer or technical buyer evaluating solver coverage before committing to a service, the safest rollout is to start with a narrow fixture, record every submitted task, and compare the solver response with the browser state that finally submits the form. That makes failures explainable instead of mysterious, especially when a target alternates between visible challenges, invisible checks, and server-side verification.

Evaluation Criteria

A benchmark article should be read as a measurement snapshot, then verified against the live leaderboard before making a purchase or migration decision. For solver evaluation work, the most useful scorecard combines technical acceptance with operational cost. A low nominal price is not enough if retries double the real cost per accepted token, and a fast median solve time is not enough if p95 latency stalls the queue. Track these criteria before you standardize the workflow:

• The challenge subtype, sitekey, action, rqdata, blob, captchaId, or page URL used for each task.
• Median and p95 solve time, separated by provider and target domain.
• Accepted-token rate on the target page, not just successful API responses.
• Retry count, timeout count, zero-balance incidents, and invalid-parameter errors.
• The exact browser, proxy region, and user-agent that submitted the solved token.

Rollout Checklist

Before this guidance moves into a production job, build a small acceptance suite around the pages that matter most. Run it with a fixed browser profile, then repeat with the proxy and concurrency settings you expect in production. Keep the first release conservative: bounded polling, clear timeout handling, and a fallback path when the solver cannot return a usable answer. For solver evaluation, compare providers on solve rate, p95 latency, API ergonomics, coverage, pricing predictability, and how quickly support resolves edge cases. That checklist keeps the article useful after the first copy-paste, because the integration is judged by end-to-end completion rather than by whether a code sample returned a string.

Monitoring Signals

Healthy CAPTCHA automation is observable. Log the task id, provider, challenge type, target host, queue time, solve time, final submit status, and normalized error code for every attempt. Review those logs in daily batches at first, then move to alerts once the baseline is stable. Sudden drops usually come from target-side changes: a new sitekey, a changed action name, a stricter hostname check, an added managed challenge, or a proxy pool that no longer matches the expected geography. When you can see those shifts quickly, provider switching becomes a controlled decision instead of a late-night rewrite.

Maintenance Cadence

Revisit the setup whenever the target UI changes, when the solver provider changes task names or pricing, or when benchmark data shows a sustained latency or solve-rate shift. Keep one known-good fixture for each CAPTCHA subtype and rerun it after dependency upgrades, browser updates, and proxy changes. If the article is used for vendor selection, repeat the same fixture across at least two providers before renewing a balance or migrating the whole pipeline. That habit keeps captcha solver type coverage work aligned with the real target behavior rather than with stale assumptions.
