Experiment Tracking Software for SaaS
GrowthLab is free experiment tracking software built for SaaS teams. Capture every hypothesis, prioritize with ICE, run a Kanban board across squads, and keep one searchable record of what worked so learnings compound instead of getting lost in scattered docs and spreadsheets.
Why SaaS teams need dedicated experiment tracking
SaaS growth runs on volume: dozens of pricing, onboarding, activation, and retention tests across teams every quarter. When that work lives in spreadsheets, Slack threads, and notebooks, results scatter and teams quietly repeat tests that already failed.
GrowthLab keeps the full lifecycle in one place. Each experiment has a hypothesis, a primary metric, an ICE score, a status, and a result. Anyone can search past tests before launching a new one, so the team builds on prior learning instead of starting from zero.
What you get with GrowthLab
The core building blocks for tracking SaaS experiments end to end.
Hypothesis capture
Log every idea with a clear hypothesis and the metric it should move, so tests are testable from the start.
- Structured hypothesis fields
- Primary and guardrail metrics
- AI-assisted hypothesis drafting
ICE prioritization
Score each idea by Impact, Confidence, and Ease to focus on the experiments most likely to pay off.
- Built-in ICE scoring
- Sort and rank the backlog
- Make trade-offs visible
Kanban pipeline
Move experiments across Backlog, Running, and Completed so everyone sees status at a glance.
- Drag and drop board
- Owner and timeline per card
- Shared across squads
Learnings library
Capture the result and what you learned, then search it later so insights compound.
- Searchable past experiments
- Win, loss, and inconclusive tags
- Avoid repeat tests
Frequently asked questions
What is experiment tracking software?
Experiment tracking software is a system of record for growth and product experiments. It stores each test's hypothesis, prioritization score, status, and outcome in one place so a team can see what is running, what has been tried, and what the results were. It is distinct from an A/B testing engine, which actually splits traffic. Tracking software manages the process and knowledge around experiments rather than serving the variants.
Is GrowthLab free for SaaS teams?
Yes. GrowthLab is free to start, with no credit card required. You can capture hypotheses, prioritize with ICE, manage a Kanban pipeline, and build a searchable learnings library on the free plan.
Does GrowthLab run the A/B tests for me?
No. GrowthLab tracks and manages your experiments, including hypotheses, prioritization, status, and learnings. You run the actual variant tests in your existing tools (for example feature flags or a web testing platform) and record the design and results in GrowthLab so everything stays in one place.
How is this different from tracking experiments in a spreadsheet?
A spreadsheet can list experiments, but it does not enforce a hypothesis structure, make ICE prioritization easy, show a live pipeline, or stay searchable as it grows. GrowthLab gives each experiment consistent fields, a shared board, and a learnings library, so the record stays useful as your test volume increases.
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.
