Compare coding agents on the tasks you give Codex CLI.
To compare an alternative to Codex, start with a task you already run in its CLI, app, editor integration, or cloud environment. Try Claude Code, GitHub Copilot, or OpenCode on the same task. Solo runs Codex CLI alongside dev servers and queue workers in a desktop app. Use it to inspect their output and status across projects. The installed agent still does the coding.
Start with the capability you want to replace. Each option overlaps with Codex in a different way.
Recommended option
Anthropic's coding agent can read files, edit code, and run commands. It has terminal and editor interfaces and supports MCP connections.
Best for
Coding with Claude in the terminal or editor.
Recommended option
GitHub Copilot has editor assistance, code review, coding agents, and a CLI. Check which features your plan and editor support.
Best for
Teams that use GitHub and supported editors.
Recommended option
OpenCode is an open source coding agent with a choice of supported model providers. Configure your provider before comparing it with your current agent.
Best for
Developers who want to choose a model provider.
Recommended option
Run Codex CLI in a Solo project with your dev server and workers. Each process has its own output and status. Solo MCP lets connected agents inspect the running commands.
Best for
Running agents and development commands in one project.
Use a small bug fix or feature with a known verification command.
Before replacing Codex CLI, run a small task in one alternative and compare the resulting code. If you want to keep the agent and track its session beside local services, try Solo with one repository.
Compare the products and workflows closest to Codex, including where Solo fits.
Start with one project and a small task. These guides walk through the setup and what to check when the work finishes.
Set up both tools in one project, give one agent implementation work, and ask the other to review the diff.
Read the guide →Give a lead agent a plan, shared todos, and a scratchpad so workers have clear assignments and a useful handoff.
Read the guide →Put a Laravel server, Vite, and a queue worker in solo.yml, then manage their output and restart behavior in Solo.
Read the guide →Solo is a lightweight desktop terminal workspace for local agents, project commands, interactive terminals, and long-running services. It sits beside your editor, keeps your stack visible, and gives Claude Code, Codex, and the rest of your tools one shared local control surface.
Solo is built by Aaron Francis, creator of faster.dev and Database School, and VP of Marketing at Laravel. He built Solo after running Claude Code alongside his own dev stack and getting tired of juggling nine terminal tabs just to keep local agents, services, and project commands visible.
He is also a dad to two sets of twins, which tends to create a strong preference for software that reduces chaos instead of adding more of it. That is why Solo keeps showing up in these comparisons as the local workspace around your tools, not another editor or orchestrator trying to absorb the whole workflow.
Free for four projects on macOS and Windows.
Start with a terminal and add the programmable meta-harness when you need to coordinate agents with your local development stack.
