Coding agent alternatives

GitHub Copilot alternatives

Compare coding agents for the work you do in GitHub Copilot.

Replacing GitHub Copilot may mean replacing editor completions, code review, or a coding agent. For agent work, compare Claude Code, Codex, and OpenCode. Test editor features separately if you rely on them. Solo runs Copilot 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.

Why people look for a GitHub Copilot alternative

You want an agent you can use without GitHub Copilot.
You need a different choice of models or providers.
You want to compare terminal agents on the tasks you currently give Copilot.

What to look for in a GitHub Copilot alternative

The files each agent changes and whether the project checks pass
Model access, account requirements, and usage limits
The permissions the agent needs to complete the task
Support for your editor and local or cloud execution

Recommended options

Start with the capability you want to replace. Each option overlaps with GitHub Copilot in a different way.

Recommended option

Claude Code

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.

Terminal and editor supportMCP connections

Recommended option

Codex

OpenAI's coding agent works in its app, CLI, editor integrations, and cloud environments. Try the interface you would use for the same task in your repository.

Best for

Local coding and tasks delegated to the cloud.

Recommended option

OpenCode

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

Solo

Run Copilot 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.

Switching guidance

Test a replacement on one task

Use a small bug fix or feature with a known verification command.

  • Start each agent from the same repository state. Use separate checkouts to keep the edits apart.
  • Give each agent the same task, constraints, and verification command.
  • Compare the diffs, check results, permissions, and manual corrections.
  • Before switching, confirm that the new tool supports the accounts and editors your team uses.
Recommendation

Test the Copilot features you use before switching. A terminal agent may cover coding tasks without replacing editor completions or GitHub review. For running a CLI agent beside local services, try Solo with one repository.

Common questions

What is the best GitHub Copilot alternative as a coding agent?

Compare Claude Code, Codex, and OpenCode for agent work. If you also rely on Copilot completions or code review, check those features separately before replacing it.

Is Solo a GitHub Copilot alternative?

Solo runs Copilot CLI and other installed CLI agents. It gives each session its own output and status alongside your project commands. You still need a coding agent to edit code and review changes.

Can I run coding agents inside Solo?

Yes. Enable the installed CLI in Settings > Agents, then launch it from the project agent picker. Use solo.yml for dev servers and workers. Their restart settings do not apply to agent sessions.

See what Solo actually is

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.

Built by Aaron Francis

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.
