GitHub Copilot vs Refact.ai (2026)

GitHub Copilot

by GitHub (Microsoft)

Refact.ai

by Refact

Pros

• ✓Available as a plugin across VS Code, JetBrains, Neovim, Xcode, Eclipse, Visual Studio, Raycast, Zed and SQL Server Management Studio, so teams keep their existing editor.
• ✓Free tier with 2,000 completions a month and no credit card, plus a free plan for eligible students, so the product can be trialed before any spend.
• ✓GitHub publishes an official open-source MCP server, hosted remotely or run locally, so Copilot both consumes external tools and exposes GitHub context to other AI clients.

Limitations

• –AI Credit metering means agent mode, code review and chat draw down a dollar-denominated allowance, and GitHub states the flex portion of that allowance may change over time, so the effective monthly budget is not fixed.
• –IP indemnity covers unmodified suggestions only and requires the duplicate detection filter to be switched on, so the protection depends on a setting an administrator has to enable.
• –Organization controls, pooled credits, usage metrics and SAML SSO require Business at $19 per user per month or above.

Pros

• ✓Free and open source under BSD-3-Clause, with users paying only the model providers they choose, including local runtimes such as Ollama, LM Studio and vLLM.
• ✓Runs entirely on the developer machine, sending requests only to configured providers and keeping project state in a local folder that can be inspected or deleted.
• ✓A task planner runs agents in isolated git worktrees, and the agent can use shell, browser, GitHub, GitLab, database, Docker and MCP integrations.

Limitations

• –No commercial support or SLA since Refact Cloud was retired, and development now rests largely on a single maintainer in a personal GitHub repository.
• –The resident background process and terminal interface are labelled an early preview, with the VS Code and JetBrains plugins described as the stable surfaces.
• –Users must install the local engine and configure their own provider keys or local models, and the refact.ai website still shows pre-shutdown messaging.
