Matt's Pick

Cursor

IDE · Anysphere
Free → $60/mo

Highest code acceptance rates, Agent mode, real-time IDE feedback

Performance: 65.7% SWE-Bench / 72% acceptance rate
Matt's 2027 Prediction

Will continue to build momentum in enterprise for the following year, but will slowly lose market share as it doesn't have much that can't be replicated by other big players.

Do you think Cursor will still exist in 2030?

GitHub Copilot

IDE/Extension · Microsoft/GitHub
Free → $39/mo

Enterprise entrenchment (90% Fortune 100), GitHub ecosystem integration

Performance: 38-42% acceptance rate
Matt's 2027 Prediction

Steady users in F500, very little indie support. Won't be going anywhere, but won't be an industry leader.
