LaunchDarkly: Developer $0 forever — unlimited seats; 5 service connections + 1K client-side MAU/mo; 5K AI runs; 10M logs + 10M traces; 5K session replays + 5K errors. Foundation PAYG (14-day trial): first 5 service connections included, then $10 per SC/mo; client-side MAU $10 per 1K/mo (yearly toggle ≈ $8.33 per 1K); AI Runs 5K included then $5 per additional 1K. Enterprise custom — footnote only. K8s / Serverless / Python / Ruby → contact sales (do not invent rates). A service connection = one server-side SDK × one environment × month; serverless may bill fractionally. Smoke: Foundation 10 SC + 10K MAU + 5K AI → SC (10−5)×$10=$50; MAU 10×$10=$100; AI $0 → $150/mo. Foundation 5 SC + 50K MAU + 15K AI → SC $0; MAU $500; AI (15−5)×$5=$50 → $550/mo.

How it works
- How much does LaunchDarkly Foundation cost?
- Foundation is pay-as-you-go: first 5 service connections included, then $10 per SC/mo; client-side MAU $10 per 1K/mo (yearly ≈ $8.33 per 1K); 5K AI runs included, then $5 per additional 1K. Example: 10 SC + 10K MAU + 5K AI = $50 + $100 + $0 = $150/mo (as of 2026-11-03).
- What is included on Developer?
- Developer is $0 forever with unlimited seats, 5 service connections + 1K client-side MAU/mo, 5K AI runs, 10M logs + 10M traces, and 5K session replays + 5K errors.
- What is a service connection?
- One server-side SDK connected to one environment for a month. Serverless and short-lived processes may bill fractionally by connection time. K8s / Serverless / Python / Ruby use custom pricing — contact sales; this calculator does not invent rates.
- What is the yearly MAU rate?
- The pricing page shows $10 per 1K client-side MAU/mo by default and ≈ $8.33 per 1K under “Billed yearly”. Toggle yearly above to use $8.33.
- What about Enterprise and Guardian?
- Enterprise is custom (advanced targeting, workflows, SCIM, longer retention). Guardian is a paid Enterprise add-on for release safety. Neither is modeled here.
