RelateDB
I built RelateDB because most free database diagram tools I tried had friction — either the UI felt limiting, key features were locked behind paywalls, or simple workflows took too many clicks.
I wanted something fast, offline-first, and frictionless: open the browser, design schemas visually, import/export SQL or DBML, and move on — no accounts, no uploads, no artificial limits.
Everything runs locally in your browser, and your data never leaves your machine.
I’d love feedback on usability, missing features

RelateDB update 🚀
RelateDB is now more than a diagramming tool.
It supports schema versioning, visual diffs, migration SQL and public read-only shareable links — all while running 100% in the browser.
No signup. No cloud lock-in. Core stays free.

Offline-first + no-account + SQL/DBML import/export is the exact “just let me sketch a schema” experience devs want. The scale pain is keeping diagrams stable as schemas grow (auto-layout + diffing) and best practice is a deterministic layout engine + schema version snapshots so changes are reviewable/undoable 🔥 Are you storing state in IndexedDB (with shareable file export), and will you add migration diffs (v1→v2 SQL) + collaborative “share a read-only link” as next steps?

@ryan_thill Yes, everything is stored locally in IndexedDB today, so it works fully offline and without an account.
I’m working toward proper schema snapshots + record-level diffs so things like migrations (v1 → v2 SQL) and undo/compare become possible. I’ll also add full workspace export/import for backup and portability.
Read-only sharing and cloud sync are on the roadmap as well.
Really appreciate the feedback, this is exactly the direction I want to take it.
This looks like a great tool for frictionless design! I’ve seen similar tools like ChartDB and DrawDB that also offer browser-based, account-free schema modeling.
Could you highlight what sets RelateDB apart from those?
RelateDB
@nick36_wu RelateDB is optimized for a fast, private, offline-first workflow — no limits. Everything runs and is saved locally in your browser. On top of that, it adds versioned schemas, migration SQL, and clean import/export (SQL & DBML) so it’s not just a diagrammer, but a lightweight schema design and evolution tool.
How could it offline-first when it require connect to a website without an option to self-host or install studio? I tried access studio and disconnect from internet and it failed when refresh. It would be perfect if it has self-hosted option. Anyway, the UI is intuitive and beautiful, love it.
Awesome!
beautiful UI.
i really need json based diagram.
Please add multiple view feature. just like in WorkBench.
so i can focus on tables related to particular module.
whole tables diagram is so distracting
Congrats on the launch — love how fast, offline-first, and no-account this is, perfect for devs who just want to sketch schemas and export SQL/DBML without any SaaS friction.

This is very cool, I love the design 👀
