Offers
Free Cloud Plan (permanently free tier) high confidence
$0/mo. Up to 50,000 API requests/month; up to 100,000 users in experiments; 1 team member; 1 project; unlimited feature flags; unlimited environments; unlimited identities and segments; API access; fair-usage policy applies. Overage billing 'starts at $50 per million per month and decreases with volume'. Free-plan users who exceed limits get 7 days to upgrade before 'any action is taken'. Verified on official pricing page 2026-10-22: numbers match the known baseline (50k requests; Start-Up $45/mo, $40 annual, 1M requests, 3 members).
Eligibility
Anyone, any size/region/education status; self-serve signup ('Start for Free' / 'Get Started!'). No .edu email requirement, no startup age or funding cap, no published region limits. No explicit 'no credit card required' statement appears on the pricing page — signup is account-based; CC requirement unverified.
How to claim
1) Go to flagsmith.com/pricing and click 'Get Started!' / 'Start for Free' on the Free tier -> 2) Create an account on app.flagsmith.com -> 3) Use within 50k requests/month and 1 team member. No application, no invoice.
Expiry
Permanently available free tier; no stated expiry. Fair-usage policy is the only caveat.
Gotchas
Fair-usage policy applies (undefined). No 2FA, no scheduled flags, no A/B & MVT testing, no 3rd-party integrations, no roles/audit logs — all Start-Up or higher. Exceeding 50k requests: 7-day upgrade window, then enforcement; overage pricing from $50/1M. Single team member + single project make it solo-dev, not team, oriented. Credit-card requirement for sign-up not stated on the page.
14-Day Free Trial of paid plans (Start-Up / Scale-Up) high confidence
Both Start-Up ($45/mo monthly, $40/mo billed yearly; 1,000,000 requests/mo; 500,000 experiment users; 3 team members; 2FA, A/B & MVT, scheduled flags, integrations, email support) and Scale-Up ($300/mo monthly, $250/mo yearly; 5,000,000+ requests/mo; up to 20 team members, extra members $50/mo; SAML/SSO, governance, audit logs, BYO experimentation warehouse) offer a '14 Day Free Trial' as listed on the pricing page.
Eligibility
Open signup; no startup-age or funding criteria stated; no .edu requirement; CC requirement for the trial not stated on the pricing page.
How to claim
1) Select Start-Up or Scale-Up on flagsmith.com/pricing -> 2) click the 14-day trial start -> 3) provisionally get full paid-plan features; decide to pay within 14 days or lose access.
Expiry
14 days from trial start; then plan becomes paid at $45/mo (Start-Up) or $300/mo (Scale-Up) unless cancelled/downgraded (downgrade path not stated on page).
Gotchas
Trial-vs-free confusion: the trial is a paid-plan preview, not an extension of the free tier; after 14 days billing presumably starts unless you cancel or switch to the free plan. Overage grace: a paid plan exceeding its request limit (within 200% of limit) for the FIRST time gets a 30-day grace period before billing; Start-Up overage is $7/100k requests. Annual plans: 12 months paid up front.
Free self-hosted Open-Source edition (Community build) high confidence
Free, 'always open' self-hosted build of the Flagsmith platform under BSD-3-Clause ('one of the most permissive open-source licences available — no restrictions on commercial use'; core repo states 'majority of our platform is open source under the BSD-3-Clause'). Includes unlimited feature flags, segments & targeting (incl. multivariate flags), remote config, server-side evaluation, 15+ open-source SDKs, A/B & MVT testing, kill switches, edge proxy, integrations (Grafana, Slack, Amplitude, New Relic), and NO API request limits on self-hosted deployments. Gated to paid Enterprise: audit logs, role-based access control / change requests / approvals, SAML/SSO, advanced governance, enterprise-grade support, on-prem/air-gapped support and optional on-prem installation.
Eligibility
Anyone — students, students' course projects, startups; no .edu email, no CC, no request caps, no team-size caps stated. Self-host on-premises or in your own cloud (GCP/AWS/Azure).
How to claim
1) Clone/deploy the open-source Flagsmith stack via Docker or Kubernetes + Helm (charts published by Flagsmith) -> 2) run it on your own infra -> 3) use indefinitely with no flagsmith.com account needed. Enterprise features add via a paid license 'without migrating platforms'.
Expiry
Indefinite; 'Core will always be open' per the page; no sunset date published.
Gotchas
You own all ops (hosting, updates, backups) — no managed free hosting. Governance/security features (audit logs, RBAC, SSO, change requests) are Enterprise-gated, so startups needing SAML/SSO must pay. Self-hosted MCP Server is 'soon' (not yet available there). License nuance: main repo is BSD-3 per WebFetch; 'a small number of repositories are under the MIT license' — check the specific repo you deploy. No official SLA/support on the free build.
Discounted plan for open-source / not-for-profit / charity projects medium confidence
The pricing FAQ answers the question 'We're an Open Source/Not for profit/Charity project. Do you offer discounts?' with '100% Yes! Please get in touch and we can set you up on a discounted plan.' No discount percentage, no eligibility checklist (no .edu requirement, no startup age, no funding cap) is published — it is a discretionary, contact-gated concession, not a formal program. Related: annual-payment discounts are offered on all plans, and bespoke tiers between Start-Up and Enterprise can be arranged via the contact form.
Eligibility
Stated for open-source, not-for-profit, or charity projects (startups doing OSS may qualify). No .edu-email criterion mentioned; education/student-specific licensing does NOT exist — /education, /startup-program and /faq all 404 as of 2026-10-22. No region limits stated.
How to claim
1) Go to flagsmith.com/pricing FAQ -> 2) contact Flagsmith (contact-us / sales) describing your project -> 3) receive a custom discounted paid plan. No self-serve application.
Expiry
No expiry, renewal or sunset terms published; discount is bespoke per negotiation. Terms (percentage, duration, renewal) are not public.
Gotchas
Discount % and plan shape are unpublished — always negotiate in writing. This is NOT an education license: no student/academic tier or .edu requirement exists. The free OSS self-hosted build already gives most of the value for free, so the discount only matters if you want managed cloud + governance features. 'Get in touch' means sales lead time; the free cloud tier and 14-day trial remain the instant paths.
No formal Flagsmith startup program, student/education license, or trial-credit offer exists as of 2026-10-22 — dedicated pages /education, /startup-program, /faq all return 404; the only concessions are the permanent free tier, 14-day paid-plan trials, the free BSD-3 open-source self-hosted build, and the contact-gated open-source/non-profit/charity discount. Current published figures exactly match the known baseline (Free: 50,000 requests/mo, unlimited flags/environments, 1 team member; Start-Up: $45/mo monthly / $40/mo yearly, 1M requests, 3 members), indicating no material pricing change is visible on the official page today. Caveats: (1) the session's WebSearch budget was exhausted, so 2025-2026 change history could not be independently verified via search engines — I verified the live official pages only; (2) the Flagsmith blog page (Sep–Oct 2026 posts) shows no pricing-change announcements on its first page; (3) one possible 2025-2026 change: the core repository now advertises a permissive BSD-3-Clause license ('no restrictions on commercial use') where Flagsmith historically used a Business Source License — I could not verify the license-change date (history was not searchable); if the repo was BSL before, that re-licensing is a material, favorable change for commercial self-hosting.
