ARQS releases ExperimentLab, a free tool for reading A/B tests correctly and shipping only real wins
ARQS has released ExperimentLab, a free browser tool for product and growth teams that run A/B tests.
FOR IMMEDIATE RELEASE
VANCOUVER, B.C., October 17, 2026 — ARQS has released ExperimentLab, a free browser tool for product and growth teams that run A/B tests. Users enter visitors and conversions for a control and a variant and see the lift, a confidence interval, the p-value, the Bayesian chance that the variant beats the control and a check that the traffic split matches the plan; a second calculator compares averages such as revenue per visitor. A planner turns a baseline conversion rate, the smallest lift worth detecting, significance and power into a sample size per variant and a run time in days, rounded up to full weeks. Each experiment in the tracker passes a six-point ship gate before it says to ship: results entered, a healthy traffic split, the planned sample reached, at least a full week of data, a significant win and a healthy guardrail metric. A feature flag list marks flags that are stalled, have no owner or are fully rolled out and ready to remove. Workspaces export to CSV or a file to reopen later. The tool needs no account or purchase, does not connect to analytics or flag services and saves only in the user's own browser.
