Claude, Cursor, Lovable: What Each Is Actually Good At
An engineer's read on the AI building tools founders ask about — where each one genuinely saves weeks, and where it quietly creates work for later.
Founders ask us which tool to use roughly once a week. The honest answer is that the tool matters less than the brief — but they are genuinely different, and the differences show up months later, not on day one.
Chat-first (Claude, ChatGPT)
Best when you are still deciding what the thing is. You can argue with it, ask it to justify a data model, make it list its assumptions. Weakest when a project grows past what fits in one conversation — context gets lost and the same file gets rewritten in two different styles.
Editor-first (Cursor and similar)
Best once there is a real repository. It sees the whole project, so changes are consistent and refactors are plausible. Assumes you can read the diff it produces — if you cannot, you are approving changes you do not understand.
App builders (Lovable, Bolt, Replit)
Fastest to something clickable, and genuinely good for proving an idea. The trade is that you inherit their structure, their hosting and their defaults. Getting out later is possible but rarely as easy as getting in — check that you can export a real repository before you build on it.
| If your goal is… | Reach for | Watch out for |
|---|---|---|
| Deciding what to build | Chat-first | Losing the thread across sessions |
| A clickable demo this week | App builder | Lock-in; check the export path |
| Changing an existing codebase | Editor-first | Approving diffs you cannot read |
| Something that takes money | An engineer reading the result | Nothing here is a substitute for that |
The thing none of them do
Every one of these tools optimises for the demo, because that is what you asked for. None of them will spontaneously add idempotent webhooks, database indexes or a restore-tested backup. That is not a flaw — it is a scope boundary. Knowing where the boundary sits is the whole skill.
If you want a second pair of eyes on what your tool produced, our 12-point checklist is the same one we run internally.
Questions
Should I start with an AI tool or hire a developer?
Start with the tool. Prove the idea cheaply, then bring an engineer to the version that has to survive real users. That order costs less and produces a better brief.
Will using AI tools make my codebase unmaintainable?
Not by itself. What makes it unmaintainable is nobody ever reading it. An hour of review every couple of weeks keeps it honest.
