Know which subscription
still has room.
OpenLimiter reads the quota of your AI subscriptions on your own machine and hands your coding agents a bounded picture of what budget is left. Open source, local first, zero telemetry, no accounts.

How it works
Three quiet steps from local files to agent awareness.
Nothing leaves your machine at any point in this pipeline.
01
Read
Parsers over data that already exists on your machine
Six connectors translate a known shape into raw meters. They perform no network access in this release, and they never rewrite the files they read.
02
Normalise
One snapshot schema, freshness derived, unknown left as unknown
Closed enums, bounded percentages, and validated timestamps. A row that fails validation is dropped and the rest still count. A missing reading never becomes a fabricated zero.
03
Advise
A statusline for you, a bounded context block for your agent
The advice engine emits enum codes, numbers, and timestamps only. Your agent sees the state of your budget and a reason code. It never sees provider text.
How it connects
One local pipeline, and an honest line around what exists.
Everything in the top band ships today and can be run from a clone in this repository. Everything in the bottom band is written down and nothing more.
Available now
Data already on your machine
Claude Code writes a session payload to your statusline command. A manual document on disk, or any script at all through the ingest command, can hand over meters the same way.
OpenLimiter CLI
Six connectors parse the shapes they know. The core validates bounds, merges one atomic cache under one lock, and derives freshness. No connector contacts a provider in this release.
Your statusline
One line, the worst meter per provider, a reason code in front. It falls back to the cache and never blocks the tool that called it.
Your agent's context
A bounded block of enum codes, numbers and timestamps on prompt submit. When every provider is unknown it injects nothing at all.
Planned, reading the same local cache. Not built.
Desktop tray
An icon next to the system clock on Windows, macOS and Linux, reading the cache the CLI already writes. There is no download, and no screenshot of it exists because it does not exist.
Mobile applications
iOS and Android, so a long window can be checked away from the desk. Nothing has been submitted to any store and there is no waiting list.
Providers
Six connectors, each labelled with how much to trust it.
There is no OpenLimiter server in this picture. A connector reads something already sitting on your machine, and in this release not one of them touches the network.
Claude

Manual

readsnumbers you write yourself
Every connector ships marked UNVERIFIED, which is the honest default: no explicit verifier has confirmed a shape against a live account yet.
Agent context
Your agent gets budget state, never provider prose.
A block injected into a prompt is an injection surface. This one carries enum codes, bounded numbers, and timestamps, and it says so about itself.

Provider text never crosses
Parsers keep known numbers and known timestamps. Labels, messages, account text, markup, and unknown fields are discarded before anything reaches policy code.
Enum codes only
The advice engine emits provider codes, reason codes, bounded percentages, freshness codes, and timestamps. The adapter validates every one of them again.
Silence beats a guess
If every provider is unknown, the hook injects nothing at all. It reads the local cache, makes no network request, and exits 0 whatever happens.
Ingestion
Three offline paths put data in front of it.
All three are local. Until one of them runs, every command honestly reports unknown rather than showing you a number it does not have.
Automatic
The Claude Code statusline payload
Claude Code writes a session object to your statusline command on every render. When it carries a rate limit block, OpenLimiter validates it, caches it, and renders the fresh numbers in the same call.
By hand
A manual document in the state directory
Write manual.json with up to ten meters and every command picks it up. A row that breaks a rule is dropped, and the remaining rows still count.
Scriptable
The generic ingest command
Any script or agent can hand OpenLimiter a document on standard input or inline. Add a provider id and the document goes to that connector's own parser instead.

Open source
Local first, and there is nothing to trust us with.
OpenLimiter runs on your machine. There are no tracking scripts, no remote logs, no accounts, and no OpenLimiter server to receive anything, because none exists. Quota state is written locally and stays there.

Roadmap
Planned, and honestly not built yet.
These three are written down so the direction is clear. None of them exists today, none can be installed, and none is on a waitlist.
Desktop application
plannedA tray icon next to the system clock on Windows, macOS, and Linux, reading the same local cache the CLI already writes.
Mobile applications
plannedApplications for iOS and Android, so a long running window can be checked away from the desk. Nothing is submitted to any store.
Encrypted synchronisation
plannedQuota state shared across your own devices, encrypted. The CLI would keep working with no account and no network either way.
Pricing
The software is free. A hosted service would not be.
Everything that runs on your machine is free and stays free. No feature is locked, and there is no tier that unlocks one.
Free, and always free
available now$0
Everything that runs locally. Open source under Apache 2.0, so this is not a trial and cannot be taken away.
- Every connector, with no provider locked behind a tier
- The statusline and the Claude Code prompt hook
- All eight CLI commands, including doctor and export
- All three ingestion paths
- No usage limit, no seat count, no account
OpenLimiter Sync
coming soon$5per month
An optional hosted add on. You would be paying for servers that cost money to run, not for software that was withheld from you. The local tool would not change in any way if you never bought it.
- Encrypted synchronisation across your own devices
- Mobile access to the same quota state
- Push alerts when a window is close to its cap
There is nothing to buy. No checkout exists, no waitlist is open, and no synchronisation service is running anywhere yet.
If you want to support the work
Sponsorship is entirely optional and buys no feature. It funds the time that goes into the connectors and the docs.
