Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.
Entry price
From $12 per seat/month plus context-based usage (indicative)
PaidFrom $45 per month (indicative, Start-up plan)
Free tierWhat drives the bill
The metric that actually scales your invoice.
Priced on seats plus monthly contexts (roughly, unique users evaluated). High-traffic consumer products get expensive.
Considerably cheaper than LaunchDarkly, and self-hosting removes usage pricing entirely.
Free tier
14-day trial; no permanent free tier.
Free cloud tier with a monthly request allowance; open-source self-hosting is unlimited.
