What’s new

Everything we’ve added to JillionDB, newest first.

v0.8

More to read before you sign up

New pages that answer the questions people ask before trying JillionDB.

  • Setup guides for Claude Code and Cursor, with a rule you can add so your agent always asks first.
  • How JillionDB compares with Atlas, Prisma, database branching and others, including where they’re stronger.
  • A Security page that says exactly how your account and keys are protected, and what isn’t there yet.
  • A pricing page, a press kit, and answers to common questions.
v0.8

Docs

Clear guides for every part of JillionDB, in all six languages.

  • Step-by-step guides to connect Claude Code, Cursor and other tools.
  • How to read a review, and what approve, edit first and reject each do.
  • Every risk JillionDB checks for, with the reason you’ll see in a review.
  • A reference for agents and developers: the tools, and how to propose a change.
v0.8

A new front page

jilliondb.com now shows what JillionDB does before you sign up.

  • Watch an agent’s proposal light up on a schema, get approved, and turn into a migration.
  • Plans and prices: Free, and Pro at $12 a month, coming soon. Every account has everything until Pro launches.
  • Privacy and Terms, written to be read.
v0.7

Try it without an account

One click opens a demo workspace with agent proposals already waiting.

  • Approve, edit or reject real proposals, and watch a new one arrive.
  • Compare saved versions, fix an issue, and look around a second project.
  • The demo opens in your language and deletes itself after 24 hours.
v0.6

Agents propose, you approve

Connect your coding agent to JillionDB and review every database change it wants to make.

  • Works with Claude Code, Cursor and any MCP client. Settings shows the exact command for each.
  • Proposals appear on your schema with their risk and a reason for each change.
  • Approve, edit first, or reject with a note. Your agent then gets the exact migration, or your note.
  • Likely renames are flagged, so data isn’t dropped by mistake.
  • Important buttons now use the JillionDB green.
v0.5

Versions, compare and migrations

See exactly what changed, how risky it is, and the SQL to apply it.

  • Save versions of a schema and compare against any of them.
  • Every change is rated safe, caution or destructive, with a plain reason.
  • Migration SQL for PostgreSQL, MySQL and SQLite, with a way to roll back.
  • Works on phones too.
v0.4

Import your database

Bring in the schema you already have, and edit it as SQL or on the canvas.

  • Paste a dump from PostgreSQL, MySQL or SQLite, or schema files from Rails, Django or Laravel.
  • Anything that can’t be imported is listed with its line before you import. Nothing is dropped quietly.
  • The SQL panel is now editable: type, and the canvas follows.
v0.3

The canvas

Design your schema visually.

  • Tables, relationships, drag, zoom, tidy layout, undo and search.
  • Edit any table, column, index or relationship in the side panel.
  • Design problems are pointed out as you work.
  • Stays smooth with hundreds of tables.
v0.1

JillionDB opens

The first version: create an account, start projects and get SQL for three databases.

  • Sign up, confirm your email, and create projects for PostgreSQL, MySQL or SQLite.
  • SQL for all three databases, tested against the real thing.
  • Available in English, Chinese, Japanese, Spanish, German and French.
