Subscription tracker for builders

Know what your dev stack actually costs.

You're paying for a dozen services across a handful of side projects. Subsy tracks the tier, the real monthly cost, the renewal date, the limits that actually constrain you — and which of your apps breaks if you cancel.

Free. Sign in with email or Google — no password to remember.

The bill creeps up quietly

Nobody sets out to spend $250 a month on tooling. It arrives one free trial at a time.

One page, the whole picture

Every service you pay for, normalised to a monthly figure regardless of billing cycle. Annual plans divided by twelve, usage costs folded in, canceled services faded but kept on the record.

The coloured ring is a freshness check: how long since you last confirmed that row is still accurate. Green under a month, amber under two, red beyond. Tap to reset.

Built around the questions you actually ask

Not a general-purpose expense tracker. A tool for people running several projects on a shared pile of subscriptions.

÷

Cost per project

Tag each service with the apps that use it. Shared costs split evenly across them, so per-project totals add back up to the real bill instead of counting the same $19 twice.

◷

Renewals before they land

Renewal dates go red inside two weeks. Annual plans stop being a surprise once a year.

▤

The limits that bite

Record only the two or three quotas that actually constrain you — build minutes, database size, seats — next to a direct link to the live usage page.

▦

Cards, not guesswork

Store which card pays for what, with brand, last digits and expiry. When a card expires you can see everything that's about to fail.

↗

Straight to the dashboard

Usage, dashboard and billing links per service. Subsy never guesses your consumption — it takes you to the page that knows.

⌘

Architecture prompt

Generate a ready-made prompt for Claude Code or Codex that combines your paid stack with your repo, and get back a diagram with costs annotated on the edges.

Your data stays yours

Subsy has no analytics, no advertising and no third-party trackers. Your records are stored against your account with row-level security, so nobody else — including other Subsy users — can read them. Export the whole lot to JSON whenever you want.
