2Captcha vs CapSolver: Detailed Price, Speed & Accuracy Comparison

2Captcha vs CapSolver is one of the most common comparisons developers research when selecting a CAPTCHA solving service. These two providers represent fundamentally different approaches: 2Captcha’s hybrid model with human workers and AI, versus CapSolver’s pure machine-learning pipeline. The right choice depends on your CAPTCHA types, volume, and whether you prioritize speed or coverage.

This comparison covers pricing, solve times, accuracy, API design, and supported types. For a broader overview of all major providers, see our complete CAPTCHA solving services comparison.

Pricing Comparison

Price is where these two diverge most clearly. CapSolver offers flat, predictable pricing while 2Captcha uses tiered rates that vary by complexity and account level.

CAPTCHA Type	2Captcha (per 1k)	CapSolver (per 1k)
reCAPTCHA v2	$1.00 - $2.99	$1.00
reCAPTCHA v3	$1.45 - $2.99	$1.50
hCaptcha	$1.00 - $2.99	$0.80
Cloudflare Turnstile	$1.00 - $2.99	$0.60
FunCaptcha	$1.00 - $2.99	$1.50
GeeTest v3	$2.99	$1.20
Image-to-Text	$0.50 - $1.00	$0.20

CapSolver is generally cheaper for token-based CAPTCHAs, particularly Turnstile ($0.60 vs $1.00+) and hCaptcha ($0.80 vs $1.00+). 2Captcha’s base rates can be competitive at the lower end of their tiers, but the variable pricing makes cost prediction harder at scale.

For image-to-text, CapSolver’s $0.20/1k significantly undercuts 2Captcha’s $0.50-$1.00 range.

Speed Benchmarks

Speed is CapSolver’s defining advantage. Because it uses AI/ML models exclusively, it doesn’t wait for human workers to claim and complete tasks.

CAPTCHA Type	2Captcha (avg)	CapSolver (avg)
reCAPTCHA v2	15-45 seconds	3-8 seconds
reCAPTCHA v3	10-30 seconds	3-6 seconds
hCaptcha	15-40 seconds	3-8 seconds
Turnstile	10-25 seconds	2-5 seconds
Image-to-Text	5-15 seconds	1-3 seconds

CapSolver is 3-5x faster on token CAPTCHAs. For workflows with concurrent tasks, this speed difference directly multiplies throughput. A scraping pipeline sending 100 concurrent reCAPTCHA v2 tasks would complete them in roughly 8 seconds with CapSolver versus 30-45 seconds with 2Captcha.

2Captcha’s speed improves during off-peak hours when more workers are available per task, but it can’t match the consistency of automated solving.

Accuracy and Success Rates

Both providers report success rates above 95% for standard CAPTCHA types, but the details matter:

CapSolver achieves 95-99% accuracy on its supported types. Because AI models are deterministic, accuracy is consistent regardless of load or time of day. However, when CapSolver fails on a task, it typically fails fast — there’s no human fallback.

2Captcha reports 96-99% accuracy on image CAPTCHAs (where human workers excel) and 90-97% on token CAPTCHAs. The human element adds variability: accuracy can dip during high-demand periods when less experienced workers handle tasks. On the other hand, humans can solve unusual or distorted CAPTCHAs that pure AI struggles with.

For standard token tasks, accuracy is comparable. For complex or unusual images, 2Captcha’s human workers provide an edge that CapSolver can’t replicate.

Supported CAPTCHA Types

This is where 2Captcha pulls ahead decisively:

2Captcha supports 20+ types: reCAPTCHA v2/v3/Enterprise, hCaptcha/Enterprise, Cloudflare Turnstile, FunCaptcha, GeeTest v3/v4, KeyCaptcha, Capy, Lemin, Amazon WAF, CyberSiARA, DataDome, MTCaptcha, Yandex, image-to-text, coordinate-based image, audio CAPTCHAs, and grid selection.

CapSolver supports 10-12 types: reCAPTCHA v2/v3/Enterprise, hCaptcha, Cloudflare Turnstile, FunCaptcha, GeeTest v3/v4, DataDome, AWS WAF, and image-to-text.

If you encounter GeeTest v4, KeyCaptcha, Capy, or other niche types, 2Captcha is currently the only option. CapSolver covers the most common 90% of use cases but leaves gaps for specialized CAPTCHAs.

API Design and Integration

The two APIs reflect their different philosophies:

2Captcha uses a legacy format (/in.php to submit, /res.php to poll for results) with form-encoded parameters and plain-text responses. It also offers a newer JSON API (/createTask/getTaskResult). The legacy format is supported by virtually every CAPTCHA-solving library in every language, giving 2Captcha unmatched ecosystem compatibility.

CapSolver uses a modern JSON-only API (/createTask/getTaskResult) with clean request/response schemas, callback URL support, and application identification. The API is well-documented with examples in Python, Node.js, Go, and more.

For new integrations, CapSolver’s API is cleaner to work with. For existing projects that already use 2Captcha-compatible libraries, switching would require code changes. This is one advantage of using an aggregator like uCaptcha — its API supports both the legacy 2Captcha format and the modern JSON format, so you can use whichever your codebase already targets.

Documentation and Ecosystem

2Captcha has the most comprehensive documentation in the CAPTCHA solving industry. Every CAPTCHA type has dedicated docs with parameters, code samples, and troubleshooting guides. The community is large, and third-party libraries exist for virtually every language.

CapSolver provides well-organized modern documentation with interactive code examples and quick-start guides. The ecosystem is growing but smaller — fewer third-party libraries and community resources.

If you’re new to CAPTCHA solving, 2Captcha’s documentation and community make the learning curve gentler. If you prefer modern API design and concise docs, CapSolver’s approach is more streamlined.

Which Should You Choose?

Choose 2Captcha if you need broad type coverage (especially niche CAPTCHAs), value extensive documentation, or need human-powered solving for complex image tasks.

Choose CapSolver if your workload is primarily token CAPTCHAs (reCAPTCHA, hCaptcha, Turnstile), speed is critical, and you want lower, more predictable pricing.

Choose both if you want the speed of CapSolver for token tasks and the coverage of 2Captcha for everything else. uCaptcha makes this practical by routing each task to the optimal provider through a single API. You get CapSolver’s speed on Turnstile, 2Captcha’s coverage on GeeTest, and automatic failover between them — no separate integrations, no manual switching.
