ReadMeter

See your Firestore reads before your bill explodes.

Get ReadMeter — $9 (one-time)

ReadMeter shows how many Firestore reads your pages trigger during development — so you can spot risky patterns early, before traffic arrives. Copy AI-ready prompts into Cursor or Claude to fix hotspots, track read history locally, and export JSON for your own analysis.

Try this interactive demo to see how a page can have hidden reads — even when it feels simple.

Most Firestore cost problems aren't caused by you.

They are caused by invisible behavior.

In development:

  • You are one user
  • Datasets are small

Everything looks fine.

In production:

  • Every page load multiplies
  • Queries run more than expected

The bill jumps

Firebase shows totals — not causes.

ReadMeter shows the causes while you’re building.

Firestore bills don't grow gradually. They jump.

Firestore charges per document read, not per query. A page that looks harmless in development can become expensive once real users start loading it.

Data is taken from a personal project that heavily uses Firestore as database.

ReadMeter exists to make those patterns visible early.

What it shows:

  • Know how many reads a page triggers before users arrive
  • Find the functions causing the most reads
  • See patterns that may scale badly with traffic
  • Copy AI-ready prompts into Cursor or Claude to fix hotspots fast
  • Track read history locally and export JSON for reporting or analysis

All visible on the page while you build — plus local history and JSON export.

The root causes

Firestore bills per document read — not per query. That’s why cost can jump unexpectedly.

Most developers only see the total after a bill arrives — not the individual patterns that caused it.

What ReadMeter is (and isn't)

ReadMeter is

  • a development-time visibility tool
  • early warning for scaling issues
  • simple and focused

ReadMeter is not

  • a billing calculator
  • production monitoring
  • a guarantee of cost reduction

One Fixed Price

If ReadMeter helps you catch just one costly pattern early, it has already paid for itself.

  • No subscription, ever
  • One device, non-transferable — your license binds to the first machine only
  • Unlimited projects and free updates
