Open a representative repository in Lapce before comparing startup screenshots. Check language support, navigation, diagnostics, formatting, search, integrated terminal, and the extensions your workflow depends on. Then repeat the test on a large file or monorepo and note latency and memory use.
Editor migration also has a human cost: keybindings, remote-development needs, and team settings. Keep your current editor available during the trial. A fast launch is valuable, but only if the full edit–test–debug loop remains dependable.
