AI coding assistants have split into two camps: cloud-first agents that maximize capability, and privacy-first assistants that maximize compliance. The right choice depends less on benchmarks and more on how your team handles code, data and budget.
The agentic leaders
Cursor remains the benchmark – its agent plans and executes multi-file changes with real repo awareness. Plans run Free, Plus $8, Premium $30 (cloud agents and AI code reviews) and up. Windsurf counters with Cascade, a proactive agent on a generous free tier and a $15 Pro plan, making it the best-value second editor.
Ecosystem vs privacy
GitHub Copilot wins on ubiquity – it lives in every major IDE and hooks into GitHub’s whole workflow. Tabnine is the compliance pick: air-gapped deployment, zero code retention and IP indemnification for regulated industries.
Our verdict
Individual developers: Cursor Premium or Windsurf Pro. GitHub-centric teams: Copilot. Regulated enterprises: Tabnine. Try the free tiers first – all four are useful without paying.
