Built for the codebase you already have, not a fresh scaffold.
TL;DR
Lovable, Bolt.new, and v0 are fast at prompt-to-app greenfield scaffolding.
None are built for existing, non-trivial codebases, real debugging, or a real test suite.
rigless works directly against a repo you already have, with a real terminal and toolchain.
If you need a fast, disposable prototype, they're legitimately faster at that specific job.
Lovable, Bolt.new, and v0 all solve a version of the same problem: go from a prompt to a working, good-looking web app as fast as possible. They're genuinely good at prototyping and greenfield scaffolding.
That's a narrower job than "software engineering." None of these tools are built for the parts of real development that dominate most engineers' time: working in an existing, non-trivial codebase, debugging something already broken, running a real test suite, or managing dependencies outside their preset list.
rigless doesn't generate a new app inside its own walled garden. It works directly against a repo you already have, however large or old, in whatever stack it's already written in. Clone it, work on a branch in a full Linux sandbox with the real toolchain, and open a pull request back to the same repo.
Prompt-to-app builders are optimized around a live preview of a generated frontend. rigless gives you an actual terminal in an actual VM: run the real test suite, start a real database, install a real dependency that isn't on some preset list.
Lovable, Bolt.new, and v0 are each tuned around a specific model and generation pipeline for their scaffolding use case. rigless works with whichever model you bring, on whatever stack your project already uses.
Lovable / Bolt.new / v0 | rigless | |
|---|---|---|
Best at | Fast, greenfield app scaffolds | Existing, real codebases |
Environment | Generated frontend + preview pane | Full Linux VM, real terminal |
Debugging existing code | Not the target use case | Core use case |
Model | Fixed to their pipeline | Any — BYO key or bundled starter |
You need a fast, disposable prototype with no existing constraints.
You're starting a brand-new app and want a generated head start.
You're working in a codebase that already exists.
You need a real environment — a real test suite, a real database, a real terminal.
You want more than a generated frontend and a preview link.
