How we compiled this
Published self-serve USD pricing was collected directly from each vendor's official pricing page on 2026-06-14. Where a page returned 4xx/5xx or contained no prices (Harness/Split — redirects to contact-sales), this is noted in provenance and monthlyUsd is set to null. LaunchDarkly Foundation is usage-based with no flat floor, so monthlyUsd reflects the minimum ($10 per service connection). DevCycle Business monthlyUsd is the annualized monthly rate ($500/mo when billed annually); month-to-month is $625/mo noted in plan notes. ConfigCat prices are monthly billing rates; annual rates were not available in published page markup. PostHog Feature Flags are usage-based with a free tier; monthlyUsd=0 for plans up to the free threshold, then metered. All telephony fields (minutesIncluded, callsIncluded, overagePerMin, overagePerCall) are null — this is a non-telephony vertical.
