Cursor vs Bolt (StackBlitz)
A plain-English comparison to help you choose between them.
A full development environment against browser-based building: Cursor is where an owned codebase gets worked, Bolt is where a new one gets running. Pick Cursor when you own your repo and toolchain and want the strongest AI woven into the editor, indexed-codebase grounding, coherent multi-file agentic edits, parallel and cloud agents taking work away and returning diffs. Pick Bolt when the point is zero-to-running, full-stack apps generated and executing in the browser through a real runtime, live preview updating as you talk, deployment leaving from the same tab. Bolt's own category framing settles the seam: its sweet spot is starting things, not maintaining them, and established codebases favour the IDE agents.
Side by side
- Summary
Cursor is the AI-native IDE: a VS Code-shaped editor rebuilt around models, where agentic editing makes coherent multi-file changes, the indexed codebase grounds every answer, and you slide between manual coding, assisted edits and delegated tasks without changing tools.
- Best for
- Agentic multi-file edits that hold together
- Codebase-grounded answers from an indexed repo
- Sliding between manual, assisted and delegated work
- Cost
- Freemium (Free tier + paid plans)
- Ease
- Openness
- Hosted service
- Data
- Check data/privacy settings and enable team privacy mode for proprietary code; the main practical risk is unpredictable credit spend, so watch the usage dashboard. Review all agent-generated changes.
- Summary
Bolt builds, runs and deploys full-stack web apps from a prompt, entirely in the browser: the agent generates the project, a real runtime executes it instantly, and the live preview updates as you talk.
- Best for
- Full-stack web apps generated and running in the browser
- Live preview that updates as you iterate by prompt
- Modern JavaScript frameworks scaffolded from a description
- Cost
- Freemium (Free tier + paid plans)
- Ease
- Openness
- Hosted service
- Data
- Projects run in-browser on StackBlitz infrastructure; exported code is yours to take anywhere.
Common questions
Where in a project's life does each win?
Bolt owns the first afternoon: scaffold, run, iterate and discard, with token metering keeping light exploration cheap and many experiments abandoned by design. Cursor owns everything after the codebase acquires weight, when changes span the system and the editor's indexed context makes agentic edits land coherently. The crossover is roughly when you stop discarding and start maintaining.
How visible is the code on each path?
Fully visible on both, unusually for this comparison family. Bolt keeps files editable throughout with a terminal in reach, built for builders who touch code as well as prompts, and reads Figma imports with unusual fidelity. Cursor is code-first by definition. The difference is not visibility but gravity: one is a browser tab around a project, the other an environment around a career.
What hardening does each output need?
Bolt says it plainly: output is real code that still needs a developer before production, with weak input validation, session handling and secret management common in generated work, so customer-facing apps get hardened first. Cursor's risk is velocity rather than scaffolding, teams shipping faster than they judge accumulate confident debt, so review scales with throughput on either path.
