Tool Breakdown
Flagsmith
Flagsmith's open-source core can be self-hosted for free with no request cap, and its hosted plans start at $40/mo — a fraction of LaunchDarkly's usage-metered pricing — making it the better default unless you specifically need LaunchDarkly's AI-agent governance tooling.
- Free self-hosted open-source core (BSD-3-Clause) with no request cap, deployable via Docker Compose
- Hosted free tier covers 50,000 API requests/month with unlimited flags, environments, identities, and segments
- Start-Up paid tier is $40/mo — far below LaunchDarkly's usage-metered entry pricing
- SAML/SSO, roles/permissions, and audit logs are gated behind the $250/mo Scale-Up tier or a separately licensed Enterprise Edition, even when self-hosting
- Hosted free tier is capped to a single team member
LaunchDarkly
LaunchDarkly is an established, closed-source feature-flag platform now repositioned around 'CodeControl' flag delivery and 'AgentControl' AI-agent governance.
- Permanent free 'Developer' tier with unlimited seats, 1 project/3 environments, and 5,000 AI runs/month
- 'AgentControl' adds AI-agent evaluation, adaptive triggers, and an LLM playground on top of standard flagging
- Established platform with a large SDK ecosystem across languages and frameworks
- No self-hosting option — cloud-only deployment
- Foundation-tier pricing is usage-metered (per service connection or per 1,000 client-side MAU), making costs harder to predict than a flat rate
Frequently Asked Questions
Can I self-host Flagsmith for free? +
Yes. Flagsmith's core is open source (BSD-3-Clause) and can be self-hosted via Docker Compose with no request cap. Some governance features like SAML/SSO and audit logs require a separately licensed Enterprise Edition even when self-hosting. LaunchDarkly has no self-hosting option at all — it's cloud-only.
Which tool is cheaper to start with? +
Flagsmith. Its hosted free tier covers 50,000 requests/month, and its cheapest paid plan is a flat $40/mo. LaunchDarkly's free 'Developer' tier is also permanent, but its paid 'Foundation' tier is usage-metered per service connection or per 1,000 MAU rather than a flat rate.
Does either tool offer an affiliate program? +
Flagsmith does — a confirmed 25% recurring commission on referrals who become paying customers, paid monthly. LaunchDarkly's Partner Program offers a free 12-month Enterprise license for technology partners but discloses no referral commission percentage.
