Firestore Data Analyzer

Firebase doesn't show you your data. This does. The Firebase console gives you a raw document browser — one document at a time, no totals, no charts, no export. Firestore Data Analyzer turns that same data into tables, instant group-by counts, and trend charts, right inside a Chrome side panel. Setup takes two minutes, and your data never leaves your browser. SEE EVERYTHING AT A GLANCE 📋 Fast, scrollable tables — large collections stream in progressively, first rows in under a second 🧮 Instant group-by — tick the fields you care about and watch counts and bar charts recompute live 📈 Automatic trend charts — date fields are detected for you, so "records per day" just appears 📂 Zero-typing setup — browse your data in the Firebase console once and your collections show up in a dropdown EXPORT IN ONE CLICK 📤 JSON for backups and scripts, CSV for data tools, Excel for spreadsheets — always the complete collection, never a partial snapshot STUCK ON "PERMISSION DENIED"? 🛡️ The built-in rules helper generates a safe, read-only rule scoped to exactly you and the collection you tried — copy, paste, retry. From error to working in under a minute. PRIVATE BY DESIGN, NOT BY PROMISE 🔒 No servers. No tracking. No account with us. Data flows directly between your browser and your own Firebase project — the extension talks to nothing else. Works on every plan, including the free Spark plan, and it can only read: it never writes, changes, or deletes anything. WHO IT'S FOR Developers checking what's actually in a collection. Founders watching sign-ups grow. Analysts who need the data in a spreadsheet — without asking a developer to write an export script. Install it, open your Firebase console, and finally see your data.
