We solve it

Fastest on the market
~250ms average. Competitors take 3-13 seconds. We're not even close — we're in a different league.
Cheapest per solve
$0.80 per 1,000 solves. Others charge $1.20-$2.99 for the same thing. Do the math.
99.9% success rate
Failed solves don't cost you anything. We only charge for tokens that actually work.
One endpoint
POST /solve. That's the entire API. No callbacks, no polling, no webhooks. Synchronous response.
Common questions
How does NSLSolver bypass Cloudflare Turnstile?
We generate valid Turnstile tokens server-side. You send us the sitekey and page URL, we return a token that passes Cloudflare's validation. Your downstream requests look identical to a real browser session.
Will the target site detect I'm using a solver?
The tokens we generate are indistinguishable from tokens produced by a real user interaction. Cloudflare validates the token itself, not how it was created.
What's the rate limit?
No hard limit. We handle bursts of 1,000+ concurrent requests. If you need sustained throughput above 10,000 req/s, contact us for dedicated capacity.
Do you support invisible Turnstile (managed mode)?
Yes. Both visible and invisible (managed) Turnstile challenges work. Same endpoint, same parameters. No changes needed on your end.
What happens if a solve fails?
You get an error response and you're not charged. We only bill for successful token generation. Our error rate is under 0.1%.
