Atom was sunset on December 15, 2022. LevelCode carries the hackable spirit forward →
Great software happens when the editor works with you. The LevelCode agent plans, edits across files, runs commands, and verifies its own work — right in your editor, on your own API key, with no middleman between you and the model.
Generate. Describe the change in plain language — LevelCode.ai writes idiomatic code in your project’s style, right in the buffer.
Every edit lands as a reviewable Keep/Undo change. Every command waits at an approval gate. Before the agent says done, it checks diagnostics and runs your tests — and every turn is a checkpoint you can rewind.
Some systems are too big for one prompt. Sketches let you drag a whole agent topology onto a canvas — eleven wired agents for a key-value store, a full leaderboard build — set the goal, hit Run, and watch them light up in order.
Drag a card onto the canvas to lay down a fully-configured agent topology.
Drop a template here
Drag a template card in — or just click it — to materialise the full topology.
Chat, edit, autocomplete, and a full agent mode — first-class in the editor, not a bolted-on plugin. Bring your own key or run local Ollama.
The Notepad++ toolkit: keystroke macros, line operations, column mode with incrementing numbers, encoding and EOL control, huge-file mode.
Debounced ghost text over every file, cancelled the instant you keep typing — routed to a fast model per provider.
Thousands of open-source extensions from Open VSX — search, install, and update without leaving the editor.
Split the interface into panes to compare and edit code across files — plus a real approval-gated terminal.
Find, preview, and replace as you type — in a file or across every project, powered by ripgrep.
Choose from thousands of open-source packages on Open VSX that add features and functionality — or build one from scratch with the live package-dev loop.
One Dark ships built in — this very page honors it in dark mode. Install community themes or restyle everything with CSS.
An init script that runs at boot and hot-reloads on save, keymap presets for Atom, Sublime, and Notepad++ muscle memory, and skills that teach the agent your workflows.
A desktop app built on Code-OSS and Electron — the same battle-tested core as VS Code, bent back toward Atom's hackable soul. MIT, forkable, yours.
