In Plain English

bolt.diy is the open-source, community-driven fork of Bolt.new from StackBlitz Labs — letting developers prompt, run, edit, and deploy full-stack web applications using any LLM they choose (OpenAI, Anthropic, Gemini, DeepSeek, Ollama, Groq, and more) on infrastructure they control.

OverviewFeaturesPricingUse CasesLimitationsFAQAlternatives

Overview

bolt.diy is a free, open-source AI App Builders GitHub template for developers who want to prompt, run, edit, and deploy full-stack web applications with their chosen LLM while keeping infrastructure, model selection, and operating costs under their own control. It is aimed at technical users who want Bolt-style AI app generation without relying only on a hosted commercial product.

The GitHub repository describes bolt.diy as a tool to “Prompt, run, edit, and deploy full-stack web applications using any LLM you want,” and the repository is public, marked as a template, and forked from stackblitz/bolt.new. That positioning matters: this is not a no-code SaaS landing page builder for non-technical teams; it is a developer-facing project hosted on GitHub under the stackblitz-labs organization. The 2026-06-15 repository capture shows 19.5k stars and 10.4k forks, which is unusually high public interest for an open-source AI app builder. It also shows 77 open issues and 39 pull requests at that capture time, which indicates active community discussion and ongoing development rather than a static demo.

The main value of bolt.diy is control. Developers can use it as a self-hosted AI coding workspace for generating and iterating on full-stack web apps, while keeping the workflow closer to their own infrastructure and model preferences. Existing listing data notes support for multiple LLM options including OpenAI, Anthropic, Gemini, DeepSeek, Ollama, Groq, and OpenRouter; that makes bolt.diy especially relevant for teams experimenting with model cost, privacy, latency, or local inference. Based on our analysis of 870+ AI tools, this combination of open-source distribution, app-building workflow, and model flexibility is more developer-centric than most browser-only AI app builders.

Compared to hosted AI app builders in our directory, bolt.diy trades convenience for autonomy. Tools like Bolt.new, Lovable, Replit Agent, and v0 are generally easier to start using because they provide hosted infrastructure and managed onboarding, while bolt.diy requires users to work from a GitHub project and operate the stack themselves. For developers, agencies, and technical founders, that tradeoff can be worthwhile: the 2026-06-15 repository capture showed 19.5k stars and 10.4k forks, reflecting strong demand for an open implementation of this style of AI development environment. For non-technical users who want billing, support, templates, and a managed deployment path, a commercial hosted alternative will usually be a better fit.

Key Features

Prompt-to-app workflow+

The repository title describes bolt.diy as a way to prompt, run, edit, and deploy full-stack web applications. That makes it more than a code snippet generator: the intended workflow spans initial generation through iteration and deployment.

Use any LLM+

The tool is positioned around letting users work with the LLM they choose rather than being tied to one provider. Existing listing data references OpenAI, Anthropic, Gemini, DeepSeek, Ollama, Groq, and OpenRouter as model options.

Open GitHub template+

The scraped page marks the repository as public and as a template. That is useful for developers who want to fork the project, inspect implementation details, or use it as a starting point for their own AI app-building environment.

Forked from Bolt.new+

The GitHub page explicitly says bolt.diy is forked from stackblitz/bolt.new. This gives users a clear frame of reference: it is aimed at a Bolt-style AI development loop, but with a community-run and self-directed distribution model.

Large developer community signal+

The 2026-06-15 repository capture shows 19.5k stars and 10.4k forks, plus 77 issues and 39 pull requests. Those figures indicate strong public interest and active contribution activity, while also reminding users to review issue history before relying on it for important work.

Best Use Cases

🎯

A technical founder wants to prototype a full-stack SaaS idea quickly while keeping the generated code and AI tooling under their own control.

⚡

An agency wants an AI app-building workflow it can fork, customize, and adapt for repeated client prototypes instead of relying only on a hosted product.

🔧

A developer wants to compare different LLMs for the same app-building task and avoid being locked into a single model provider.

🚀

A team wants a Bolt-style prompt-run-edit-deploy loop but needs a public GitHub project it can inspect before adopting.

💡

An engineer wants to experiment with AI-assisted full-stack generation while retaining the ability to modify the underlying project.

🔄

A privacy-conscious developer wants to explore local or self-managed model workflows rather than sending every build step through a managed SaaS.

Limitations & What It Can't Do

We believe in transparent reviews. Here's what bolt.diy doesn't handle well:

  • ⚠The provided website content does not show a managed hosted version, so setup and operation are likely developer responsibilities.
  • ⚠No official paid support, SLA, or enterprise plan is visible on the scraped GitHub page.
  • ⚠The repository’s 77 issues in the 2026-06-15 capture indicate that users should expect some unresolved edge cases or active maintenance work.
  • ⚠The total cost is not fixed because model provider usage, hosting, and deployment costs are external to the visible GitHub pricing information.
  • ⚠It is less suitable for non-technical users than hosted no-code or low-code app builders.

Pros & Cons

✓ Pros

  • ✓Public GitHub template with strong community signal: 19.5k stars and 10.4k forks were visible on the repository page in the 2026-06-15 capture.
  • ✓Forked from stackblitz/bolt.new, so it targets the same prompt-run-edit-deploy workflow rather than a generic chatbot coding interface.
  • ✓Designed around user-selected LLMs, which gives technical teams more flexibility than app builders tied to a single model provider.
  • ✓The repository is public, so developers can inspect the code, fork it, and adapt the implementation to their own infrastructure.
  • ✓The project shows active development signals with 77 issues and 39 pull requests visible on the GitHub page in the 2026-06-15 capture.
  • ✓Best suited for developers who want more control over their AI app builder stack than hosted-only products usually allow.

✗ Cons

  • ✗No hosted product or managed onboarding is visible in the provided website content, so users should expect a developer-led setup process.
  • ✗The GitHub page shows 77 issues and 39 pull requests, which can mean users may encounter unresolved bugs or fast-moving changes.
  • ✗Pricing for model usage, hosting, and deployment is not published on the repository page, so total cost depends on the user’s own setup.
  • ✗Non-technical users may find it harder to use than hosted AI app builders because the primary website is a GitHub repository.
  • ✗Commercial support, enterprise SLAs, and managed security documentation are not visible in the provided website content.

Frequently Asked Questions

What is bolt.diy used for?+

bolt.diy is used to prompt, run, edit, and deploy full-stack web applications with AI assistance. The GitHub repository title explicitly describes this workflow and emphasizes that users can use any LLM they want. In practice, it is best understood as a developer-controlled alternative to hosted AI app builders. It is most useful when a technical user wants to generate and iterate on a web app while keeping more control over the tooling and model choices.

Is bolt.diy free?+

The provided website content shows bolt.diy as a public GitHub repository and public template, and no paid pricing tiers were visible in the 2026-06-15 capture. That means there is no listed subscription price on the scraped page. However, using the tool may still involve external costs such as LLM API usage, local compute, hosting, or deployment infrastructure. Users should treat the software access as free from the visible GitHub listing, but not assume the full operating cost is zero.

How popular is bolt.diy?+

The 2026-06-15 GitHub capture shows 19.5k stars and 10.4k forks, which are strong public adoption indicators for an open-source developer tool. The repository is also marked as public and as a template, which makes it easier for developers to start from and adapt. At the time of capture, the page also showed 77 issues and 39 pull requests. Those numbers suggest both broad interest and an active development surface that users should evaluate before production use.

Who should choose bolt.diy instead of a hosted AI app builder?+

Choose bolt.diy if you are a developer, technical founder, or agency that wants more control over the AI app-building environment. It is particularly relevant when model flexibility, self-hosting, source-code access, or infrastructure control matters more than turnkey onboarding. Based on our analysis of 870+ AI tools, this is a more technical option than most hosted AI app builders in the directory. Non-technical users who want a managed interface, billing, and support may be better served by a hosted competitor.

Is bolt.diy the same as Bolt.new?+

No. The scraped GitHub page identifies bolt.diy as a public template repository forked from stackblitz/bolt.new. That relationship means it is connected to the Bolt.new code lineage, but it should not be treated as the same managed hosted product. bolt.diy is positioned as an open-source, developer-run project, while Bolt.new is generally used as a hosted app-building experience. The choice depends on whether you value convenience or control more.
