Supermaven

Supermaven won its devoted following on a single measurable advantage: speed. Its custom-built model infrastructure delivers completions so fast — roughly a millisecond-class latency where competitors stretch into hundreds — that suggestions arrive before your fingers finish the keystroke, collapsing the awkward pause-and-accept rhythm that makes other assistants feel like friction. The in-line UI deserves equal credit: an expanding preview of the whole suggested change (not just the next few tokens) lets you accept a complete logical unit with one press, keeping your attention inside the code rather than in a suggestion panel.

Context handling is the second pillar: a 600,000-character context window (later models exceed 1M) reads your entire repository rather than a few open files, which shows in the quality of suggestions across module boundaries — it knows the utility function you wrote last week and uses it correctly. For teams, the shared-codebase awareness means suggestions improve as colleagues commit, a quiet form of institutional memory.

The strategic chapter since Cursor's parent acquired Supermaven has slowed standalone development, which honest buyers should weigh: the plugin remains maintained and beloved, but the team's energy flows to the editor product. Pricing stays accessible — a genuinely useful free tier, then ~$10/month for Pro with larger context and frontier models. Our verdict: for developers who want the fastest, least intrusive autocomplete available today — especially in VS Code and JetBrains — Supermaven is still the latency benchmark. If you want an agent, look to its sibling; if you want suggestions that never make you wait, nothing matches it.
