Try GitHub Copilot →Same price, different bets. Supermaven wins on raw completion speed and free-tier generosity; Copilot wins on breadth — better chat, agent mode, and deeper editor integrations. Speed purists pick Supermaven; everyone else gets more tool for the money with Copilot.
In independent developer reports, yes — Supermaven's custom model is tuned specifically for low-latency completions, and the difference is noticeable on long files.
Supermaven's free tier is genuinely usable long-term. Copilot's trial is short, so try Supermaven first, then trial Copilot when you're ready to compare.
Copilot, today: Business/Enterprise tiers with admin controls and organization-wide policies are more mature. Supermaven is catching up but team features remain thinner.
