A/B testing
A/B test your real app in plain English
Describe the test you want on the app you already ship. ronda writes the variant into your actual code and opens a pull request your engineers review. The split runs in your code, so there is no visual overlay and no flicker.
Why this is different
The variant lives in your code, not on top of it
Most no-code A/B tools give a marketer a visual editor that paints changes over the live page at runtime. That approach flickers on modern apps built in React or Next.js, because the visitor sees the original for a moment before the variant loads, and it leaves a separate visual layer your engineers have to maintain. The lightweight experiment engines like PostHog and GrowthBook avoid the overlay, but they expect a developer to wire each test into the codebase. ronda sits between the two. A non-engineer describes the test in plain English against your real app, ronda writes the variant directly into your code, and it opens a pull request your engineers review before anything ships. The split-test logic is part of your rendered app, so the assigned variant shows immediately with no overlay step.
Four steps
From an idea to a reviewed experiment
- 1
Describe the test
Point at the element you want to test in a live preview and describe the variant in plain English, for example a different headline or a new call to action.
- 2
ronda writes the variant
ronda makes the variant change in your actual code and wires the experiment into your own PostHog project so assignment and results are tracked.
- 3
Your engineers review
The change lands as a standard GitHub pull request. An engineer reads the diff and merges it, so nothing reaches users unreviewed.
- 4
You launch when ready
ronda prepares the experiment and stops before launching traffic. You start the test yourself in PostHog when you want it live.
Why teams use ronda for this
Real code, reviewed before it ships
No overlay flicker
The variant is in your rendered code rather than painted over the page, so visitors see the assigned variant directly with no flash of the original.
A reviewed pull request
Every experiment lands as a pull request your engineers approve. A non-engineer sets the test up; an engineer signs off before it ships.
Your own PostHog
ronda wires the experiment into your own PostHog project with your key. Assignment, exposure, and results stay in the analytics tool you control.
Questions
A/B testing with ronda
Do I need a developer to set up an A/B test?
Not to set it up. A non-engineer describes the test in plain English against your real app, and ronda writes the variant into your code. 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 test flicker on my React or Next.js app?
No. Visual-editor tools paint the variant over the page after it loads, which can flash the original first. ronda puts the variant in your rendered code, so the visitor sees the assigned variant directly with no overlay.
What handles the traffic split and the results?
Your own PostHog project. ronda wires the experiment into PostHog, which assigns variants and reports results. You connect PostHog with your own key, so the data stays in the tool you control.
Does ronda launch the experiment for me?
No. ronda prepares everything and stops before launching traffic. You review the pull request, merge it, and then start the experiment yourself in PostHog when you are ready for it to go live.
What does this cost?
ronda has a Free plan at $0 and a Starter plan at $9 per month. Both are bring-your-own-key, so you connect your own Anthropic key for the AI and your own PostHog project for the experiment data, and you pay those providers directly.
