Now in beta · SDK for Node.js + Python

Never get surprised
by a rate limit again.

QuotaWatch monitors your outgoing API calls in real time — before the 429s hit. Drop in two lines of code. Get a live dashboard. Sleep better.

Free tier · No credit card · 2-minute setup

APIs break silently. You find out from users.

Rate limits hit in production. Invoices arrive with surprise charges. No single place to see how much of your quota you've actually used — across OpenAI, Stripe, Twilio, SendGrid. You're flying blind.

No visibility

You don't know you're at 90% until the first 429 fires.

No aggregation

Usage is scattered across dashboards for 6 different providers.

No early warning

Alerts come after the damage — from users in production.

Set up in minutes

No infrastructure changes. No proxies. No config files.

01

Install the SDK

One package, two lines of code. Wraps your existing fetch or requests calls — zero changes to your application logic.

import { QuotaWatch } from 'quotawatch';
QuotaWatch.init({ apiKey: 'qw_live_...', apis: [...] });
02

Monitor in real time

Every API call is captured asynchronously — fire-and-forget. Never in your critical path. Your app always goes first.

03

Get alerted early

Set thresholds at 80% and 95%. Get an email before you hit the wall, not after. Configure per-API, per-environment.

Everything you need

Built for developers who care about production reliability.

Real-time dashboard

Per-API usage cards with quota progress bars. Color-coded: green, amber, red. See your entire API surface in one view.

Passive SDK interception

Wraps global fetch (Node.js) and requests/httpx (Python). Completely fire-and-forget — never delays your requests.

Threshold alerts

Email alerts at 80% and 95% of your configured limit. Deduped per reset window — no alert storms.

Multi-environment

Separate views for production, staging, and development. Same API key, different environments.

Simple pricing

Start free. Upgrade when you need more.
