Your credits are quietly dying.
QuotaCanary watches the balances you connect and warns you before one runs dry.
A bird's-eye view of your credit stack.
If it's in the directory, the canary is watching it. If it isn't, tell us and we'll take a look.

Don't see yours? Ask for it, or add it yourself - an adapter is three small files.
Three steps. Then we never bother you, until we have to.
The whole job: you never learn a tool died by watching a campaign fail. A balance is a number. A deadline is something you can act on, so that's what we give you.
120 left, burning 240/dayburns out tomorrowConnect your stack.
An API key. We read your balances and nothing else - not your sends, not your contacts, not your message bodies.
We watch. Quietly.
Every 15 minutes we check what you've got left, and how fast it's draining. The math is unforgiving.
The bird warns you while there's still time.
Before a tool runs dry, not the morning after. Enough lead time to top up before anything breaks.
Free,
while we figure it out.
- Every balance you connect, one dashboard
- Burn-rate forecasts that name the day you run dry
- Low-balance alerts to Slack or any webhook
- Per-balance thresholds you control
- Read your balances over a plain API
- An MCP server, so your agents can check too
No credit card. No "talk to sales." There is no sales.
I run cold outreach pipelines for a living. Every few weeks a campaign would die at 3am, and after an hour of digging the cause was always the same: one vendor out of ten had quietly run out of credits. Some tools auto-top-up. Some send a warning email. The rest just stop.
QuotaCanary is the thing I kept wishing existed: one page that watches the balances I care about and says something while there's still time. I run it on my own stack every day. If it saves one of your campaigns, tell someone. That's the entire growth strategy.
Questions you'd ask before handing over an API key.
Three things. We translate balances into deadlines ("burns out next Thursday," not "120 left"), watch all your connected tools at once instead of making you check seven tabs, and warn you before the credits hit zero. That's the whole product.
By default, one low warning while there's still time, and one critical alert when it's gone. That's it. You can turn up the volume, but we'd rather you didn't have to.
No. We only read the usage endpoint. We don't ingest contacts, see message bodies, or touch outbound. Use a scoped key where your tool offers one; plenty only issue an all-or-nothing key, and we won't pretend otherwise. The whole security model is public.
QuotaCanary tracks tools that expose quota through a simple read-only API call. Platforms like RapidAPI that only expose usage through dashboards or traffic headers are out today, because chasing those turns a free tool into a science project. Ship a clean quota endpoint and we'll add you: Apollo used to be named right here, and now it's tracked. The directory is the full list; if yours is missing, ask and we'll take a look.
Yes. There's a read-only REST API, a remote MCP server your agent can call, and outbound webhooks for the alerts themselves. Same scope as everything else - it reads your balances and nothing more. Setup's in the docs.
Yes to both. The full source is on GitHub, so you can read exactly what we do with your API keys instead of taking our word for it. Prefer to run the whole thing yourself? Fork it and self-host - your laptop, your own server, wherever you like. The hosted version stays free either way.
Polling your balances every 15 minutes costs us almost nothing, so we don't charge for it. If a paid tier ever shows up, it'll be for something genuinely expensive, and you'll see it coming long before it touches you.
Birds in coal mines noticed bad air before the miners did, which gave everyone time to leave. Ours does the same job for credit balances. We added singing because it was cuter than the alternative.
