Everything in one place

A real IDE, not a text box

PolyIDE bundles the tools you'd normally juggle across a heavy desktop install — all working together, instantly.

🧠

Smart code intelligence

Autocomplete, hover docs, go-to-definition, find-references and rename across files — powered by real language servers.

🐞

Step debugging

Breakpoints, conditional breakpoints, watch & evaluate, call stack — for Node and Python, right in the editor.

⌨️

Integrated terminal

A real shell that survives reconnects and select-to-copies — run commands, REPLs, and tests without leaving the browser.

🗄️

PolyData SQL studio

Connect to SQLite, Postgres, MySQL & SQL Server. Browse, edit grids, and design tables visually — like SSMS.

🌿

Built-in Git

Stage, commit, branch, and view diffs from a panel — no context switching.

👥

Teams & companies

Company accounts with admins, roles, seats, shared workspaces and connections — for individuals up to enterprise.

  • Native desktop builds when you want them
  • Cloud workspaces sync your projects anywhere
  • Self-host it on your own server

Questions

Frequently asked

Is it really free?

Yes — PolyIDE is free forever for individual developers, with no time limit. Paid plans add team features, shared workspaces, and priority support for businesses.

Do I need to install anything?

No. PolyIDE runs entirely in your browser. Native desktop apps for macOS, Windows, and Linux are available if you prefer, and both stay in sync.

Which languages are supported?

37 and counting — including Python, JavaScript, TypeScript, Go, Rust, C, C++, C#, Java, PHP, Ruby, SQL, Bash, and more, with autocomplete, running, and debugging where applicable.

Is my code private?

Your workspaces are yours. PolyIDE can be self-hosted on your own server for full control, and code execution runs in isolated sandboxes on the hosted plan.

Can my whole team use it?

Yes. Create a company account, invite members, assign admin/member roles, manage seats, and share workspaces and database connections across the team.

Does it work offline?

Yes — the desktop app keeps working without a connection, and syncs your cloud workspaces when you're back online.
