A Google Optimize alternative that does not need a developer
Google Optimize shut down in September 2023. ronda lets a non-engineer set up an experiment on the app you already ship, in plain English, and opens a pull request your engineers review.
Google Optimize was a free A/B testing tool that let marketers change a page and split traffic without writing code. It was shut down in September 2023, and the tools people moved to fall into two camps. The heavy platforms like Optimizely and VWO are powerful but expensive, and their visual editors often inject changes over your page at runtime, which can flicker and behaves poorly on modern single-page apps built in React or Next.js. The lightweight engines like PostHog and GrowthBook are accurate and fairly priced, but they expect an engineer to wire the experiment into the codebase. ronda takes a different path. You describe the experiment in plain English against your real app, ronda makes the variant change in your actual code, and it opens a pull request your engineers review before anything goes live. The split-test logic runs in your code rather than as an overlay, so there is no flicker and no separate visual layer to maintain.
Side by side
ronda vs Google Optimize
| Dimension | ronda | Google Optimize |
|---|---|---|
| Status | Active and maintained. | Shut down by Google in September 2023. |
| Who sets up the test | A non-engineer describes the variant in plain English; an engineer reviews the result. | A marketer built variants in a visual editor without code. |
| How the variant is built | A real code change in your repository, scoped and reviewable. | A visual edit applied over the live page through the Optimize snippet. |
| Where the change lives | In your GitHub repository, as a pull request with a diff. | In the Optimize project, layered onto the page at runtime. |
| Review before launch | Your engineers read the diff and approve it in your normal workflow. | Marketers published variants directly from the tool. |
| Flicker on modern apps | None. The variant is in the rendered code, not painted over it. | The overlay approach could flash the original before the variant on React or Next.js pages. |
| Cost | Free plan, and Starter at $9 per month. Bring your own AI and analytics keys. | Was free. No longer available. |
| Analytics and stats engine | Uses your own PostHog project for assignment and results, connected with your key. | Used Google Analytics for goals and reporting. |
| Framework support | Auto-detects React, Vue, Svelte, and Angular; monorepo-aware; Docker-first. | Snippet-based, so it ran on most sites but struggled with client-rendered apps. |
| Launching traffic | ronda prepares the experiment and stops before launch; you start traffic yourself in PostHog. | You started the experiment from the Optimize console. |
| Best fit | A team with a real coded app that wants experiments in the codebase, reviewed by engineers. | Was a fit for simple marketing-page tests on server-rendered sites. |

ronda is the better choice when
- You ran Google Optimize on a real coded app and need a replacement that does not require an engineer for every test.
- You want the A/B variant to live in your code as a reviewed pull request rather than as a runtime overlay.
- Your app is built in React or Next.js and visual-editor tools flicker or break on it.
- You already use PostHog, or are willing to, and want experiments wired into it without a developer doing the plumbing.
- Every change to the live product has to pass engineering review before users see it.
Google Optimize is the better choice when
- You are reading this for historical context; Google Optimize is no longer available to choose.
- Your need is a simple visual tweak on a server-rendered marketing page with no codebase to speak of.
- You want a free tool tied directly to Google Analytics and are evaluating what Optimize used to offer.
Questions
What teams ask before switching
What replaced Google Optimize?
Google recommended moving to a third-party A/B testing tool integrated with GA4. The common destinations are Optimizely and VWO on the heavy end, and PostHog and GrowthBook on the lightweight end. ronda is a fit if you want experiments set up by a non-engineer and shipped as code your team reviews, using your own PostHog project for assignment and results.
Do I need a developer to run an A/B test with ronda?
No, not to set it up. A non-engineer describes the experiment in plain English against your real app. ronda makes the variant change in your code and opens a pull request. An engineer reviews and merges the pull request, which is the safety step, but they do not have to build the test from scratch.
Will the variant flicker the way overlay tools do?
No. Visual-editor tools paint the variant over your page after it loads, which can flash the original first on React or Next.js apps. ronda puts the variant in the rendered code itself, so the visitor sees the assigned variant directly with no overlay step.
How does ronda decide which visitor sees which variant?
ronda wires the experiment into your own PostHog project, which handles assignment and reporting. You connect PostHog with your own key. ronda prepares everything and stops before launching traffic, so you start the experiment yourself in PostHog when you are ready.
What frameworks does ronda support?
ronda auto-detects React, Vue, Svelte, and Angular, is monorepo-aware, and is Docker-first. Each session runs your real dev server in an isolated sandbox container so the preview reflects your actual app.
