Firebase Studio
Browser-based agentic development environment that prototypes full-stack apps and deploys them to Firebase.
+ Goes from prompt to a deployed Firebase-backed app without leaving the browser.
− The App Prototyping agent is Next.js-centric and the cloud IDE can feel sluggish.

+ Startup and typing latency are far lower than any Electron-based AI editor.
− Extension ecosystem is small compared with VS Code and Windows support only arrived in 2025.
+ Tab autocomplete predicts multi-line edits across files better than any competitor.
− Usage-based pricing changes and request limits on Pro have repeatedly frustrated heavy users.
+ Deepest GitHub integration: assign an issue to Copilot and it opens a PR.
− Completions and agent lag behind Cursor and Claude Code in quality despite more models being offered.
+ Works with local Ollama models or any API, with fully customisable config.
− Setup is more fiddly than Copilot and autocomplete quality depends entirely on the model you choose.
+ Uses the IDE's own semantic index and refactorings, so edits respect project structure.
− Quota-based AI credits run out quickly on the lower tiers.
