Using GridTerm with Open Code and Other Open Source AI Agents
The AI coding agent ecosystem isn’t just Claude Code and Codex. There’s a growing set of open-source terminal agents — Open Code, Aider, Continue, and others — that bring AI-assisted development to the command line without vendor lock-in.
GridTerm works with all of them. If it runs in a terminal, it runs in GridTerm.
The open-source agent landscape
Open Code — A lightweight terminal coding assistant. Smaller scope than Claude Code but fast and configurable. Good for quick edits and focused tasks.
Aider — Multi-model AI pair programmer. Explicit file context management, git-aware commits, architect mode for planning. The most mature open-source option.
Continue — Open-source AI coding assistant. Works as both a VS Code extension and a terminal tool. Supports multiple model backends.
Others — New open-source agents appear regularly. The terminal interface is the common thread — they all need a shell to run in.
Why multi-terminal matters for open source
Open-source agents tend to be more focused than proprietary ones. Each does one thing well rather than trying to handle everything. That makes them ideal for a multi-agent workflow where you assign different tools to different tasks.
Example 2x3 layout:
- Terminal 1: Open Code for quick file edits
- Terminal 2: Aider with Claude backend for complex refactoring
- Terminal 3: Claude Code for broad codebase tasks
- Terminal 4: Dev server
- Terminal 5: Tests
- Terminal 6: Git
Three different agents, each playing to its strengths, all visible at once.
Advantages of mixing agents
Cost control. Open-source agents with local models (via Ollama) are free to run. Use them for simple tasks and save your API budget for complex work with Claude Code or Codex.
No single point of failure. If one API is down or rate-limited, your other agents still work. A mix of local and cloud models means you’re never completely blocked.
Different perspectives. Different models and agents approach problems differently. Running the same refactoring task through two different agents sometimes reveals approaches you hadn’t considered.
Experimentation. New agents ship constantly. In GridTerm, trying a new one is as simple as installing it and opening it in a free terminal pane. No integration work, no plugin setup.
Setting up a mixed-agent workspace
Create a GridTerm workspace with your preferred agent mix:
| Terminal | Auto-command | Purpose |
|---|---|---|
| 1 | claude | Heavy lifting, complex tasks |
| 2 | aider --model ollama/codellama | Quick edits (free, local) |
| 3 | open-code | Focused file operations |
| 4 | npm run dev | Dev server |
| 5 | — | Git and testing |
| 6 | — | Free terminal |
Save this workspace and load it each morning. Every agent launches automatically in its configured directory.
Tips for multi-agent open source workflows
Start with what works. Don’t try to use five different agents on day one. Start with one you know well (Claude Code or Aider) and add others as you identify tasks they’re better suited for.
Keep a free terminal. Always have at least one terminal without an agent for git operations, manual testing, and running builds.
Use screenshots for cross-agent context. Need to share output from one agent with another? Screenshot it and paste. Two seconds.
Match the agent to the task. Don’t use a heavy cloud model for renaming a variable. Don’t use a local model for a complex multi-file refactor. The right agent for the right job.
