13x vs Codeium
Free AI autocomplete and chat across many editors.
13x is a local-first control workspace that runs your coding agents in parallel — with named rigs, a codebase map and live pulse. Here is how the two compare.
Codeium is a solid free autocomplete and chat layer. Choose 13x once you have graduated to running coding agents and need a local control room — a grid, named rigs, a codebase map and pulse — not just completions. Keep Codeium in your editor; run your agents in 13x.

Codeium is great for
- Generous free tier and fast completions
- Works across a wide range of editors
- Built-in chat and code search
13x is better when
- Cloud-hosted with opt-out data use — not local-first
- An autocomplete layer, not an agent control workspace
- No parallel-agent grid, rigs, map or pulse
If you're you are moving from completions to agentic coding
13x, because 13x is the control room for running agents, not an editor plugin.
If you're you want your context built locally
13x, because the 13x map and context packets never leave your machine.
If you're you run more than one agent at a time
13x, because the grid gives each a slot with live pulse.
run your agents in one local grid.
Launch a rig, map your codebase, send less context and watch every session's pulse — all on your machine.
