// what's inside

A real IDE, not a toy editor.

Everything you'd expect from a desktop IDE — in a tab, with nothing to install and no account required.

local-first

Your files stay yours

Open a folder and edit it directly on your disk. Save writes to your computer — we never store or see your code.

github · more hosts soon

Connect your repo

Sign in with GitHub and open a repository as your workspace — Save commits & pushes back. GitLab, Bitbucket & Hugging Face are coming soon.

Feature Store

Install plugins — TODOs, Markdown preview, and more — or build your own with the extension API.

version control

Full Git, built in

Branches, staging, commits, stash, and merges with in-editor conflict resolution.

assistant

AI, bring your key

Wire up your own API key and get an assistant in the editor — free on every plan.

Desktop apps

Prefer native? The desktop app runs your code locally and stays in sync with the web.

// how local-first works

Three steps. Nothing touches our servers.

Modern browsers can read and write a folder on your machine with your permission. PolyIDE uses that — so your project lives with you, not us.

STEP 01

Open a folder

Pick a folder on your computer. PolyIDE reads it directly — the file tree is your disk.

Open Folder
STEP 02

Edit & save

Write code with autocomplete and syntax highlighting. Save writes straight back to the file on disk.

⌘S
STEP 03

Keep it or push it

It's already on your computer. Or connect a Git repo and push — your call, every time.

// bring your own repo

Open a repo from GitHub — more hosts coming.

Connect GitHub to sign in and open a repository as your workspace. Save commits & pushes it right back — no cloud middleman, no storage fees. GitLab, Bitbucket, and Hugging Face are on the way.

No sign-up to edit and save locally. Sign in when you want your repos, teams, and settings to follow you.
