Marketing edits without a ticket
A product marketer rewrites hero and pricing copy against the live preview and opens a pull request. An engineer merges it the same day, with no Jira ticket and no Figma round-trip.
Small changes shouldn't wait on engineering.
Marketing, design, and product describe the change in plain English. ronda writes the code and opens a pull request. Engineering reviews and merges.

What is ronda
Plain-language code changes, shipped as real pull requests
ronda is a tool that lets non-engineers safely change a real web app. Connect a GitHub repository and describe the change you want in plain English. ronda applies it in an isolated live sandbox running your actual dev server, then opens a standard GitHub pull request your engineering team reviews and merges.
Works on your real repo
AI app builders generate throwaway projects from scratch. ronda edits the codebase you already ship, so there is no new framework to learn and no migration.
Every change is a reviewable PR
Nothing reaches production unreviewed. Each edit lands as a branch and pull request, so engineers stay in control and merge through their normal workflow.
Driven from the AI you already use
Run ronda from Claude, Cursor, or ChatGPT over MCP using your own Anthropic API key. It works as one tool in your agent's chain.
From request to merged PR without the ticket queue
Designers ship the polish
A designer adjusts spacing, button styles, and design tokens on the real app and shares the preview link for sign-off. The change lands as a reviewable diff instead of a redline handed back to engineering.
Engineers keep their focus time
Small label, copy, and layout tweaks that used to interrupt engineers now arrive as PRs from the rest of the team. Engineers review and merge them, and get back the focus time those interruptions used to cost.
From idea to merged PR in three steps.
A/B test, branch, and ship without engineering on call.
Beyond the describe-it-see-it loop, ronda gives non-engineers two tools usually reserved for product teams.
A/B experiments
Run real A/B tests in one prompt
Ask for a split-test in plain English. ronda writes both variants, wires the feature flag in your repo, and creates the experiment in PostHog. The pull request lands ready to merge. You click launch when you want traffic to start.
Connects to your PostHog. Results flow back into the dashboard you already use.
Side-by-side variants
Try two or three takes on the same change
Ask for variants instead of one answer. ronda generates each version on its own branch and lets you switch between them in the preview. Pick the winner and the others are cleaned up automatically.
Taste-driven iteration for marketing, design, and brand decisions where analytics would take weeks.
Drive ronda from the AI you already use
ronda plugs into Claude, Cursor, ChatGPT, and anything else that speaks MCP. Your AI can work alongside its other tools and push edits straight to a PR.

Frequently asked questions
What is ronda?
ronda lets you change a real web app by describing what you want in plain English. You connect a GitHub repository, ronda runs your actual app in a live sandbox, applies the change, and opens a pull request your team reviews and merges.
Do I need to know how to code to use ronda?
No. You describe changes in everyday language, like "make the headline bolder" or "change the pricing copy". ronda writes the code and your engineers review the pull request, so non-technical teammates can ship safely.
How is ronda different from Lovable, v0, or Bolt?
Those tools generate brand-new apps from scratch. ronda works on your existing production codebase. It edits your real repository and ships changes as standard GitHub pull requests, so there is no rewrite and no new framework to adopt.
Does ronda work with my existing codebase?
Yes. Connect a GitHub repo and ronda boots your real dev server in an isolated sandbox, then edits your actual source files. It supports React and Next.js, Vue and Nuxt, Astro, and more.
Is ronda safe to use on a production app?
ronda never pushes to production. Every change happens in a disposable sandbox and lands as a pull request on a branch. Your team reviews and merges it through the same workflow you already use.
Can ronda set up A/B tests?
Yes. Connect your PostHog workspace, then describe the test in plain English. ronda writes both variants, wires the feature flag, opens a pull request, and creates the experiment in PostHog. You decide when to launch traffic. For quick taste tests without analytics, ask for variants and pick the winner in the preview.
How much does ronda cost?
ronda has a free plan at $0 with one project, one sandbox at a time, and one collaborator. The Starter plan is $9/month with five projects, five sandboxes per project, and unlimited collaborators. Both plans are bring-your-own-key, so you use your own Anthropic API key and pay Anthropic directly for AI usage.
Which AI assistants can drive ronda?
ronda exposes its actions over the Model Context Protocol (MCP), so you can run it from Claude, Cursor, ChatGPT, or any MCP-capable agent. You can also paste useronda.com/skill.md into tools that consume skill files.
How long does it take to get started?
It takes under five minutes. Sign in with GitHub, connect a repository, and describe your first change. No credit card required.
