The first decision is whether you still want another AI-native editor or the local environment outside the editor entirely.
Windsurf started as Codeium (~$243M raised), was rebranded, and has had a turbulent ownership history — a failed $3B OpenAI acquisition, a $2.4B Google talent deal that took the founders, and then Cognition acquiring the remaining product for roughly $250M in July 2025. It is a VS Code fork with the Cascade flow-aware agent, a proprietary SWE-1.5 model, Supercomplete Tab (unlimited free completions), live previews, and MCP support. Pricing is competitive: free with 25 credits per month, Pro $15/mo, Teams $30/mo. It runs on macOS, Windows, and Linux.
Solo is the strongest alternative when the problem is editor-centric local sprawl around agents, services, and startup commands. It gives you a desktop process dashboard with solo.yml, auto-restart, file-watch restarts, CPU/memory monitoring, and native desktop notifications. Cursor (widely reported as heavily funded) is strong if you still want an AI-first editor with more resources, 8 parallel background agents, and 40+ AI models. Zed (~$42M raised, free GPL v3) is strong if you want a faster open source editor with ACP and 20+ agents.
