# Lovable

Lovable is an AI app builder that Cole relies on as his default for front-end work: "we have Lovable. This is my solution to build out almost all of my front-end applications for everything that I'm doing with AI." Like [bolt.new](./bolt-new.md), it is optimized around Claude 3.5 Sonnet and typically outputs a Vite + React project, "this is built with vite and react, that's typically what lovable and bolt will spit out for you."

Cole's most common pattern is to use Lovable as the starting point of a build and then hand off: "we just started with lovable, built our app there, and then moved it into bolt DIY to do a bunch of improvements." He also treats an earlier Lovable build as the comparison baseline when evaluating new [models](../../concepts/model-selection.md), for instance judging a DeepSeek R1 front-end against it, and used Lovable to build the first version of the Dynamous community landing page, so it recurs as his [rapid-prototyping](../../concepts/rapid-prototyping.md) benchmark.

Against [bolt.new](./bolt-new.md) and [bolt.diy](./bolt-diy.md), Cole finds the tools "pretty comparable" but with distinct strengths: Lovable "does a bit better" on certain app-style builds, while bolt is stronger at landing pages. One concrete [deployment](../../concepts/agent-deployment.md) advantage: chatting with a local agent "will not work within bolt. new or bolt. DIY because the web container actually blocks requests to the localhost agents, so lovable is a bit better in this way." He notes its output does not always "look the best" out of the box, a reminder that generated front-ends still need iteration.

## Realizes

- [Rapid Prototyping](../../concepts/rapid-prototyping.md) - building a fast proof of concept with managed services first, then hardening only what proves out; Lovable is Cole's front-end prototyping benchmark.
- [Agent Development Lifecycle](../../concepts/agent-development-lifecycle.md) - a repeatable blueprint from planning and a minimal proof-of-concept through database, code, UI, testing, and deployment.

## Contrasts with

- [bolt.new](./bolt-new.md) - StackBlitz's commercial AI coding platform that generates entire full-stack applications; Cole finds the two comparable but with distinct strengths.
- [bolt.diy](./bolt-diy.md) - the open fork Cole hands Lovable builds off to for further improvements.
- [v0](./v0.md) - Vercel's AI front-end generator that builds Next.js/shadcn UI components and whole front ends from natural-language prompts, with an npx install command to pull the generated component into a local project.

## Related

- [Model Selection](../../concepts/model-selection.md) - choosing the right LLM per task; an earlier Lovable build is his baseline for judging new models.
- [Agent Deployment](../../concepts/agent-deployment.md) - getting agents to production, where Lovable's ability to reach localhost agents is an edge over bolt.
- [Agent Security](../../concepts/agent-security.md) - sandboxing agents, scoping permissions, and keeping secrets out of the model.
- [Agent Protocols](../../concepts/agent-protocols.md) - emerging standards that let agents interoperate and be called across clients.
