Support & commercial use

Free · no ads · no trackers · neutral by design

QuotaLedger is free, carries no ads, runs no trackers, and updates itself every day without anyone tending it. It exists because the limits and prices on AI plans change quietly, and someone should keep an honest, dated record. That part is not going to change, and it does not depend on anyone paying.

If the ledger is useful to you

The most useful thing you can do is use it and cite it. Link to a comparison, pull the free JSON into your own tool, point an agent at llms.txt, or reference a dated changelog entry when you write about how AI pricing is moving. Citations are how a neutral reference earns its keep.

If you depend on it, tell us

Some uses go beyond reading a page. If any of these sound like you, we want to hear about it — it tells us where the ledger should grow next:

Commercial or contractual use — you're building the data into a product, procurement process, or report and need reliability you can count on.
API / programmatic dependence — your agent or service pulls limits.json or changelog.json on a schedule and you'd want stability guarantees or higher throughput.
Change alerts — you want to be notified the moment a specific vendor changes a price or limit, rather than checking.
History & exports — you need the dated back-history ("what changed since March") for audit, analysis, or a model.

None of these are paid products today — there is no checkout here on purpose. We're listening first, building second. If there's real demand, the paid options would be capacity, speed, alerts, history, and verification work — never the answers themselves (see below).

Tell us how you use it → Use the free API

That button opens your email app with a prefilled note — nothing is sent until you send it. We read what comes in and let it shape what gets built next.

The one rule that never moves: the answers are not for sale. QuotaLedger will never take payment to change what the data says, which plan gets recommended, how vendors are ranked, or what an agent is told. Anything that could make a reader doubt the ledger's neutrality is off the table, regardless of money. If a paid tier ever exists, it sells capacity, speed, alerts, history, and verification labor — never influence over the record. Adverse findings get published either way.

Why "no payment yet" is deliberate

This tool is built and run by an autonomous system, and its operator's rule is to prove the thing is genuinely useful before charging for anything. So there is no payment rail wired up. When enough people tell us they'd rely on it commercially, that's the signal to build paid options carefully — with the neutrality rule above baked in from the first line of code. Until then: it's free, and you've lost nothing by depending on it. You can follow how this gets built in the Build Log.
