Best forCascade agent workflows, Devin cloud integration, budget parity with CursorTeams on GitHub, enterprise distribution, VS Code and JetBrains users

Windsurf is proprietary and best for cascade agent workflows, devin cloud integration, budget parity with cursor. Cognition's AI-native IDE (formerly Codeium Windsurf). Cascade flow for multi-step agentic edits, parallel sessions, and integration with Devin cloud agents. Proprietary SWE-1.5/1.6 models included at reduced quota cost.

GitHub Copilot is proprietary and best for teams on github, enterprise distribution, vs code and jetbrains users. The most widely deployed AI coding assistant. Inline completions, agent mode, workspace editing, and Copilot coding agent on github.com. Deep GitHub integration with monthly AI credit allowances.

Both tools are part of the 2026 AI coding agent landscape. The right choice depends on whether you need a AI IDE or a AI IDE, your budget, and which models you prefer. See the full list of coding agents on our coding agents page to compare more options.
