Utilbox Rate Limit Checker – Visual API rate limit testing without code
Summary: Utilbox Rate Limit Checker sends concurrent requests to APIs, visualizes X-RateLimit-Remaining headers in real-time, and identifies when 429 errors occur. It enables developers to test API rate limits accurately without writing code.
What it does
It fires multiple requests to an API endpoint, displays response headers showing remaining request quotas, and detects the exact point when rate limits trigger 429 errors.
Who it's for
Developers needing to verify and monitor API rate limits without creating custom scripts.
Why it matters
It eliminates guesswork in rate limit testing by providing clear, visual feedback on API request thresholds and failures.
