The rule we apply: Bolt for the spike, Cursor for the build. Treat Bolt as a prototyping tool and accept the handoff cost when you outgrow it.
Where Bolt.new wins
- Prototype-to-URL speed. The fastest in this category.
- Stakeholder demos. A working URL in minutes is a different conversation than a Figma file.
- Throwaway internal tools. Where the lifetime is bounded and the spike-quality is fine.
Where Cursor wins
- Sustained iteration. Bolt optimises for the first run; Cursor optimises for the hundredth.
- Production code shape. Cursor produces code that fits team conventions because the engineer is in the loop.
- Hosting flexibility. Cursor does not assume a deploy target; Bolt does.
Cost comparison
Bolt's usage tiers compound for sustained work; Cursor's per-seat is more predictable at scale. For prototypes, Bolt's economics are fair. For production, Cursor wins on output-per-cost.
Three scenarios, three decisions
- Show a stakeholder a working idea today: Bolt.
- Build a SaaS product over months: Cursor.
- Prototype today, productionise next month: Bolt then Cursor; budget the handoff.

Oliver runs Digital Signet, a research and product studio that operates ~500 production sites with AI agents as the engineering layer. The Digital Signet portfolio is built using a continuous AI-agent build pipeline, one of the largest agent-operated publishing operations on the open web. The handbook draws directly from those deployments: real cost data, real failure modes, real recovery patterns.
