Supermaven - Pros & Cons

Pros

  • Industry-leading speed at 250ms latency, roughly 3x faster than competitors like GitHub Copilot
  • 1 million token context window on Pro/Team plans allows understanding of entire large codebases across multiple files
  • Integrated chat supports multiple AI models (GPT-4o, Claude Sonnet, GPT-4) without leaving the editor
  • Works across VS Code, JetBrains IDEs, and Neovim — covering most professional development setups
  • Generous free tier with fast completions and no usage caps on core code suggestions
  • Adapts to individual coding style and project conventions over time on paid plans

Cons

  • Free tier lacks the 1 million token context window, limiting its effectiveness on large codebases
  • Coding style adaptation is restricted to Pro and Team plans, reducing personalization for free users
  • No support for editors beyond VS Code, JetBrains, and Neovim (e.g., no Emacs, Sublime Text, or browser-based IDEs)
  • 7-day data retention limit applies across all plans, which may concern developers wanting longer history
  • Chat credits are capped at $5/month per user even on paid plans, limiting heavy chat usage

Windsurf (now Devin Desktop) - Pros & Cons

Pros

  • Agentic feel is closer to 'pair-programmer' than Cursor's chat-driven model
  • Multi-file edits with inline diffs are excellent for whole-feature work
  • MCP client support is mature — real tool use, not just chat
  • Devin Cloud access from inside the IDE post-acquisition is a unique combo
  • Enterprise VPC + SAML/OIDC option is rare among agentic IDEs
  • Free tier is still usable for hobby projects

Cons

  • Mid-rebrand to 'Devin Desktop' is confusing — docs, billing, marketplace are inconsistent
  • Cascade is aggressive — when it picks a wrong direction it can break code across many files
  • Pro price rose from $15 to $20/month, and the new $200 Max tier surprised some users
  • Indexer can lag on very large monorepos, slowing the first edit
  • Cursor's UX is still smoother for many users coming from VS Code
