ronda vs Bolt
Bolt builds and runs a new app in the browser from a prompt. ronda edits the app you already ship and opens a pull request your engineers review.
Bolt (Bolt.new, by StackBlitz) is an in-browser AI app builder. You describe an app and it scaffolds, runs, and lets you iterate on it inside the browser environment. ronda is built for the opposite case: the app already exists in a GitHub repository your team owns. A teammate points at a real element in a live preview, describes the change in plain English, and ronda opens a standard pull request against that repository. Bolt is strong for fast greenfield iteration. ronda is strong when the codebase is real, an engineering team maintains it, and the change has to land through review.
Side by side
ronda vs Bolt
| Dimension | ronda | Bolt |
|---|---|---|
| Primary job | Change a specific part of an app that already exists. | Scaffold and run a new app from a description. |
| Starting point | A GitHub repository you already own and run. | A prompt describing the app you want to build. |
| Where the code runs | Your real dev server in an isolated container per session. | An in-browser environment running the generated app. |
| Output of a change | A pull request on your repository, with a reviewable diff. | An updated generated app in the browser; export to bring it out. |
| Review and merge | Your existing GitHub review workflow. An engineer reads the diff and merges. | Iteration is in the browser; merging into a team repo is separate. |
| Regression risk on an existing app | Scoped diffs reviewable before they merge; targeted at one change. | Built to generate and run a fresh app, not to edit yours precisely. |
| Git history | Preserved. Every change is a commit on your branch. | Your repository history is not the working surface. |
| Who is expected to drive it | A PM, designer, or marketer changing a known page. | Anyone building or prototyping a new app quickly. |
| Framework support | Auto-detects React, Vue, Svelte, and Angular; monorepo-aware; Docker-first. | Generates apps on its supported web stacks. |
| Sandbox isolation | Each session is an isolated container running your actual app. | In-browser runtime for the generated project. |
| High-risk changes | Risky edits go through a preview-and-approve step before anything commits. | You re-prompt and regenerate; there is no PR gate by design. |
| Element-level targeting | Click an element in the live preview; ronda maps it to the source file. | You describe changes by prompt rather than pointing at live DOM. |
| Team collaboration model | Non-engineers propose, engineers review and merge in GitHub. | Collaboration happens inside the builder environment. |
| Bring your own AI key | You connect your own Anthropic API key. | AI usage is part of the product plan. |
| Agent-drivable | An MCP server lets Claude, Cursor, or ChatGPT drive ronda end to end. | Driven through its own product surface. |
| Pricing model | Free plan (1 project, 1 sandbox, 1 collaborator, bring your own key). Starter $9/mo (5 projects, 5 sandboxes per project, unlimited collaborators, bring your own key). | Plan-based; check Bolt for current pricing. |
| Best fit | An existing product a small team ships and maintains. | Spinning up and iterating on a new app fast. |

ronda is the better choice when
- You have a production app in a GitHub repo and need to change it, not regenerate it.
- A PM, designer, or marketer should ship the change without a git seat or the CLI.
- Every change must clear your normal pull-request review before it reaches users.
- You need full git history and zero regression risk on the code your team owns.
- You want an agent to drive the change over MCP and return a reviewable pull request.
Bolt is the better choice when
- You are starting a new app and want it scaffolded and running in the browser fast.
- You are prototyping and do not yet have a repository or a team workflow.
- You want to iterate in a single in-browser environment without local setup.
- A solo builder wants to ship a new project end to end without engineers.
Questions
What teams ask before switching
Can ronda continue a project I started in Bolt?
Once your project lives in a GitHub repository you control, you connect it to ronda and your team makes changes through pull requests. ronda works on the repository, so the step that matters is getting the code into GitHub, after which ronda picks it up.
Why not just rebuild the change in Bolt and copy it over?
Rebuilding means an engineer has to reconcile generated code with your existing structure and history. ronda makes the change in context against your actual code and opens the pull request directly, so the diff is scoped to exactly what changed.
Is the preview my real app or a generated one?
It is your real app. Each ronda session runs your actual dev server in an isolated sandbox container, so what you see in the preview is the code that will be in the pull request.
What stops a change from breaking production?
Every change is a pull request your engineers review before merging. Higher-risk edits also go through an explicit preview-and-approve step before anything is committed. The sandbox is isolated, so trying a change never touches production.
Which frameworks does ronda work with?
ronda auto-detects React, Vue, Svelte, and Angular, is monorepo-aware, and is Docker-first, so it adapts to the app you already run instead of a fixed generation target.
