Works with the APIs you already depend on

You've been here before.

It's 2:47am. PagerDuty goes off. Checkout is broken.

Three engineers are digging through logs. Someone's checking the Stripe dashboard. Someone else is on AWS. A third is on hold with support. Nobody knows which API actually failed—or why.

By the time you find it, you've lost £14,000 in transactions and your on-call engineer is updating their LinkedIn.

Or it's the silent killer: a runaway process burning through your OpenAI tokens. By the time finance notices the invoice, you've blown six months of budget in a weekend.

Rate limits don't announce themselves. Until now.

02:47— PagerDuty alert
$ grep -r "429" logs/
$ stripe balance_transactions list --limit 1
$ aws cloudwatch get-metric-statistics ...
...
Error: Rate limit exceeded

One dashboard. Every API. Zero surprises.

Predictive Alerts

Get notified at 70%, 85%, 95%—not at 100% when it's already broken. Throttl learns your consumption patterns and warns you before spikes become outages.

Unified Visibility

Every API in one view. No more tabbing between Stripe, OpenAI, SendGrid, and AWS dashboards. See your entire stack's rate limit health at a glance.

60-Second Setup

Paste your API credentials. That's it. Throttl auto-detects rate limit headers, normalises the data, and starts monitoring. No SDK. No code changes.

Rate limit data, unified

Throttl normalises rate limit headers from any API into a consistent structure.

{
  "api": "stripe",
  "remaining": 42,
  "limit": 100,
  "reset_at": "2026-02-28T12:00:00Z",
  "percent_used": 58,
  "status": "healthy"
}

X-RateLimit-Remaining, RateLimit-Reset, retry-after, x-rate-limit-requests-remaining—we speak all of them.

From zero to monitoring in under a minute.

01

Add your API

We handle the rest

Throttl auto-discovers rate limit headers, normalises the chaos, and starts tracking immediately.

Built for teams where downtime costs money.

Fintech & Payments

When Stripe or Plaid hits a limit, transactions fail. Throttl gives you advance warning so you can throttle gracefully—not apologise to customers.

AI-Powered Products

LLM APIs are expensive and unpredictable. Catch runaway processes before they drain your OpenAI budget or tank your Anthropic credits.

SaaS & Integrations

Your product depends on third-party APIs your customers never see. When HubSpot or SendGrid throttles you, their experience breaks. Know before they do.

We're onboarding 10 teams this month.
