Local-first coding agent · launching soon
Ship agents that actually touch your codebase.
c0d3r works on your real files, with a real shell and a real language server. Plan first, build second, and run Claude Code, Codex or a local model in the same session.

The GiiS Bridge runs Claude Code and Codex through their official CLIs and never stores or copies their credentials. Type /claude or /codex to hand them the terminal, then come straight back.
What's inside
Built for real repos, with brakes.
Powerful enough to change a codebase. Careful enough that you'll let it.
Claude Code and Codex as models.
Use your existing subscriptions inside c0d3r. Your logins stay with them.
Zero-setup offline mode.
LM Studio and Ollama are found automatically. Your code never leaves the machine.
Rules it can't talk its way past.
Config-only hooks run before and after every tool call, and can allow, block or rewrite it. No plugin code needed.
Branch a session from any message.
Try another approach without losing the first. Git-backed snapshots let you roll a session back, file changes included.
Same agent, two ways in.
Run it in your terminal, or use the desktop app with session history and the diff viewer.
Drive it from the browserThe GiiS Bridge links the chat.giis.ai web app to your desktop, so you can run Claude Code or Codex there from any device.
SubagentsGeneral, Explore and Scout split up work, search fast and research dependencies, in parallel or by @mention.
Skills and MCPReads your Claude Code skills as-is (.claude, .c0d3r and .agents folders), with full MCP support including OAuth sign-in.
Language server (LSP)Real code intelligence for navigation, not string matching.
Disciplined editingExact-match edits that fail loudly, structured multi-file patches, and no file edits through the shell.
Diff viewerFile tree with split or unified diffs against your working tree, main, or just the last turn.
How a session goes
Plan. Build. Review. Rewind.
- 01Plan
Start in the read-only Plan agent. It maps the code and proposes changes without touching a file.
- 02Build
Press Tab. The Build agent edits with exact-match tools and runs your tests.
- 03Review
Open the diff viewer and check every change by file, split or unified.
- 04Rewind
Not right? Roll the session back to any message and the file changes go with it. Undo the rollback if you change your mind.
The real thing
Terminal and desktop.
Launching soon · included in every plan, even free

FAQ
c0d3r questions.
What is c0d3r?
c0d3r is an AI coding agent for your terminal, with a desktop app that adds session history and a diff viewer. The new c0d3r is launching soon and will be included in every GiiS plan, even the free one.
Is c0d3r a Claude Code alternative?
c0d3r is the agent; you choose the model. It can use Claude Code and Codex through your existing subscriptions, your own API key, or a free local model in LM Studio or Ollama.
Does my code leave my machine?
With a local model in LM Studio or Ollama, your code never leaves your machine. With a cloud model, it goes only to the provider you choose.
How much does c0d3r cost?
c0d3r will be included in every GiiS plan, including the free Start Up plan. You pay only your own model provider, or nothing with a free local model.
