Flagsmith

What it is for

Flagsmith is an open-source feature-flag desk: you toggle a flag on a project, and Cloud Free is $0 (50,000 requests/month, 1 team member, unlimited flags / environments / identities / segments). Use it when the job is flags you start at $0, not when you need a $20 chat seat.

What makes it unique: the cover is the official Flagsmith Features list (Flagsmith Demo Project, ab-test, checkout-v2, isHero, values, on/off) from the GitHub still — not a pricing card. The table itself is ops of Feature flags.

Key features

• Feature flags — a named toggle (or multivariate value) you ship without a deploy (Features still; pricing Unlimited Feature Flags). One switch. Environments and the cover on/off column are ops of this. SDKs are install.
• Segments — an audience rule you reuse across flags (pricing Unlimited Identities and Segments). A group, not a toggle. Fair-usage on Free; the cover feature_segment_flagsmith_sample_user row is a flag using a segment, not a second desk.
• Identities — a per-user override (pricing Identities). One person, not a segment. Traits you send with /identities count as API requests.
• Change requests — an approval before a flag moves (pricing Governance Features). Scale-Up and up. A review, not a toggle. Roles, permissions, and audit logs sit on this card.
• Self-host / Cloud — the BSD-3 app you run, or Flagsmith Cloud (GitHub; pricing Cloud / Private Cloud / Self-Hosted). A control plane, not a flag. Private Cloud and air-gapped rows are Enterprise hosting, not a sixth flag type.

Scheduled flags, A/B / MVT, and 3rd-party integrations print on Start-Up — they are options of Feature flags, not extra desks. API requests are the Cloud meter.

Who it's for

Best fit: app teams who will stay on Cloud Free at $0 (50k requests/month, 1 member) or self-host while they ship a first Features table, then move to Start-Up at $40/month billed yearly ($45 monthly) when they need 1M requests, 3 members, scheduled flags, and email support.

Limitations / costs

• Free is 50k requests/month and 1 member. A teammate seat or 1M requests is Start-Up.
• $7/100k is the printed Start-Up overage after grace. A chatty /flags loop is a bill, not a second card.
• Change requests are Scale-Up. Governance is not on Free or Start-Up.
• A flag desk, not an experiment OS. For flags plus experiment warehouse on the same Cloud bill see GrowthBook. For an OSS flag server you already listed see Unleash.

Alternatives

• Unleash — OSS feature flags when you want Unleash’s strategy model instead of Flagsmith’s Features table.
• GrowthBook — experiment-first flags when you will not buy Flagsmith Scale-Up for a warehouse.
• PostHog — product analytics with flags when the job is events, not a dedicated flag desk.
