Where Claude Code is better
- The models. Claude models are among the strongest coding models available, and Claude Code is tuned for them.
- The ecosystem. MCP servers, hooks, skills, subagents and IDE integrations make it very extensible.
- Teams and enterprise. Admin controls, support and a large community.
Where Gritcode is better
- Running cost. DeepSeek V4 costs far less per token, and Gritcode's context management is tuned to keep long sessions cheap. There's also a free tier with no key.
- A native GUI. Rendered markdown, collapsible tool cards, a file tree, an editor and a ▶ Play button that runs your project without spending tokens.
- Footprint. The app is 10.5 MB, compared with 892 MB for the Claude desktop app, and it idles at 58 MB of RAM against about 1.8 GB for the Claude app.
- Openness. It's GPLv3 and needs no account. You can read exactly what it sends to the model.
- Session replay. Export a session to a
.gritsessionfile and replay its prompts in a new project.
