A/B Test Management Tool
GrowthLab is a free A/B test management tool that organizes your testing program around hypotheses, prioritization, status, and results. It does not split traffic itself. It manages the process and the learnings so your A/B tests stay organized and your team stops repeating ones that already failed.
Management vs. running the test
There are two distinct jobs in A/B testing. One is running the test: splitting traffic and measuring the result, which feature flag and web testing platforms handle. The other is managing the program: deciding what to test, in what order, who owns it, and what you learned.
GrowthLab is the management layer. It keeps the backlog prioritized, shows what is in flight, and stores results so the next round of tests builds on the last. Pair it with whatever A/B engine you already use.
What GrowthLab manages for you
The workflow around your A/B tests, kept in one shared place.
Test backlog
Collect every A/B test idea with a hypothesis and target metric instead of scattered notes.
- Structured hypotheses
- Primary metric per test
- One shared backlog
Prioritization
Use ICE scoring to decide what to test next based on Impact, Confidence, and Ease.
- Built-in ICE scores
- Ranked backlog
- Clear trade-offs
Status tracking
A Kanban board shows which tests are queued, running, and finished.
- Backlog, Running, Completed
- Owners and timelines
- Visible to the team
Results and learnings
Record outcomes and what you learned, then search them before launching the next test.
- Win, loss, inconclusive
- Searchable history
- No repeat tests
Frequently asked questions
Does GrowthLab run A/B tests?
No. GrowthLab manages the A/B testing program around your tests: the hypotheses, prioritization, status, and results. The actual traffic split is handled by your A/B testing or feature flag platform. You record the test design and outcome in GrowthLab so the full program stays organized in one place.
Why use a test management tool instead of just my A/B platform?
Most A/B platforms focus on running and measuring individual tests, not managing the broader program. They rarely give you a prioritized backlog, a clear pipeline across teams, or a searchable learnings library. A management tool like GrowthLab fills that gap so your testing stays strategic, not ad hoc.
Is it free?
Yes. GrowthLab is free to start with no credit card required. Backlog management, ICE prioritization, the Kanban board, and the learnings library are all available on the free plan.
About GrowthLab
GrowthLab is a free experiment management tool for growth and product teams. Unlike A/B testing and feature-flag tools built for engineers, it helps teams prioritize, run, and learn from experiments in one place, with AI-assisted experiment design, ICE and ROTI scoring, and a compounding learning library.
