Direct answer: at published prices (annual for LaunchDarkly/Flagsmith, monthly for Unleash/Statsig), using one set of scenarios — 3/10/20 team members, 10/50/200 service connections, 2K/50K/500K client MAU and 2M/20M/100M requests or events — feature-flag platforms in 2026 cost about: 3-person LaunchDarkly 58.33, Flagsmith 90, Statsig 150, Unleash 225; 10-person Unleash 750, LaunchDarkly 858.17, Statsig 900, Flagsmith 1,250; 20-person Unleash 1,735, Statsig 4,900, Flagsmith 5,750, LaunchDarkly 6,106.67 per month. The ranking flips with scale: LaunchDarkly is lowest for a small team on connection/MAU billing; Unleash wins for mid/large teams on seats plus 53M requests; event-billed Statsig beats Flagsmith and LaunchDarkly at 100M. Align the five units — seats, connections, MAU, requests and events — before comparing unit prices.
This guide is for engineering, platform and procurement teams running releases, progressive rollouts, A/B tests and kill switches. Data cut-off: 6 November 2026; prices come from the US pricing pages of LaunchDarkly, Unleash, Flagsmith and Statsig, in USD, excluding tax; all TCOs are editorial calculations, not vendor quotes. The four vendors meter different things, so official facts, editorial assumptions and non-comparable items are kept separate.
LaunchDarkly has no seat fee and bills service connections + client MAU; Unleash is 75/seat/month with 53M API requests included; Flagsmith Start-Up is 40/month for 3 members/1M requests, Scale-Up 250/month for 5 members/5M requests with 50/member overage; Statsig Pro is 150/month for 5M events with unlimited seats and flag checks. The same “feature flag” need is metered completely differently, so “price per seat” is not a valid comparison.
Five meters: seats, connections, MAU, requests, events
LaunchDarkly: Foundation is usage-based; service connections are 5 free, then 10 each/month annual (12 monthly); client MAU is 1K free, then 8.33/1K annual (10/1K monthly); seats are unlimited and not charged. A service connection is one server-side SDK connected to one environment; replicas, workers and dev/staging environments count. Unleash: Pay-As-You-Go is 75/seat/month, includes 53M API requests/month, then 5/million; client MAU and connections are unlimited; self-hosted has a 5-seat minimum. Flagsmith: Start-Up 40/month annual (45 monthly), 3 members and 1M requests; Scale-Up 250/month annual (300 monthly), 5 members and 5M requests, up to 20 members with 50/member/month overage; requests beyond the allowance are 50/million. Statsig: Developer is free with 2M events; Pro is 150/month with 5M events, unlimited seats and unlimited flag/config checks; events beyond 5M are 50/million.
| Platform | Metered unit | Published price/allowance | Not separately charged |
|---|---|---|---|
| LaunchDarkly Foundation | Service connections + client MAU | 5 connections free, then 10 each/month annual; 1K MAU free, then 8.33/1K annual | Unlimited seats, unlimited flags |
| Unleash PAYG | Seats + API requests | 75/seat/month; 53M requests included, then 5/million | MAU, connections, flags unlimited |
| Flagsmith Start-Up | Team members + requests | 40/month annual; 3 members, 1M requests; overage 50/million | Flags/environments unlimited (fair use) |
| Flagsmith Scale-Up | Team members + requests | 250/month annual; 5 members, 5M requests; 50/member overage, up to 20 | SSO, governance, audit |

Three tiers: LaunchDarkly wins small, Unleash wins mid/large
Under the same assumptions: 3 people, 10 connections, 2K MAU and 2M requests/events — LaunchDarkly 58.33, Flagsmith 90, Statsig 150, Unleash 225; 10 people, 50 connections, 50K MAU and 20M — Unleash 750, LaunchDarkly 858.17, Statsig 900, Flagsmith 1,250; 20 people, 200 connections, 500K MAU and 100M — Unleash 1,735, Statsig 4,900, Flagsmith 5,750, LaunchDarkly 6,106.67. Annual prices in LaunchDarkly / Unleash / Flagsmith / Statsig order: small 700 / 2,700 / 1,080 / 1,800; mid 10,298 / 9,000 / 15,000 / 10,800; large 73,280 / 20,820 / 69,000 / 58,800.
| Scenario | LaunchDarkly | Unleash | Flagsmith | Statsig |
|---|---|---|---|---|
| 3 people / 10 connections / 2K MAU / 2M requests·events | 58.33 | 225.00 | 90.00 | 150.00 |
| 10 people / 50 connections / 50K MAU / 20M | 858.17 | 750.00 | 1,250.00 | 900.00 |
| 20 people / 200 connections / 500K MAU / 100M | 6,106.67 | 1,735.00 | 5,750.00 | 4,900.00 |
Editorial calculation, not a quote. LaunchDarkly = max(0, connections − 5) × 10 + max(0, MAU − 1,000)/1,000 × 8.33; Unleash = seats × 75 + max(0, requests − 53M)/1M × 5; Flagsmith = plan fee + max(0, seats − included) × 50 + max(0, requests − included)/1M × 50; Statsig = 150 + max(0, events − 5M)/1M × 50. Excludes tax, enterprise, SSO/SCIM, audit, support, implementation, migration and observability/experimentation overage. The 2M/20M/100M figure is API requests for Flagsmith/Unleash, metered events for Statsig, and has no equivalent request meter at LaunchDarkly; this is not a like-for-like workload comparison.
Annual view: 1.7× spread at 10 people, 3.5× at 20
Multiplying monthly by 12: at 3 people LaunchDarkly 700, Flagsmith 1,080, Statsig 1,800, Unleash 2,700; at 10 people Unleash 9,000, LaunchDarkly 10,298, Statsig 10,800, Flagsmith 15,000; at 20 people Unleash 20,820, Statsig 58,800, Flagsmith 69,000, LaunchDarkly 73,280. The 20-person spread reaches 3.5×: Unleash’s 53M request allowance covers most mid-volume usage and the seat fee dominates; LaunchDarkly does not charge seats, but 200 connections + 500K MAU push the bill up as services and users grow.
| Annual (USD) | LaunchDarkly | Unleash | Flagsmith | Statsig |
|---|---|---|---|---|
| 3-person tier | 700 | 2,700 | 1,080 | 1,800 |
| 10-person tier | 10,298 | 9,000 | 15,000 | 10,800 |
| 20-person tier | 73,280 | 20,820 | 69,000 | 58,800 |
Editorial calculation, not a quote. Monthly × 12; excludes tax, enterprise, add-ons, implementation, migration and support. LaunchDarkly uses annual rates; monthly billing for 10 connections + 2K MAU is 70/month (840/year), above the annual 58.33/month (700/year). Flagsmith annual prices already save more than 10%; Unleash/Statsig are published monthly prices.
Why the ranking flips: four cost curves
LaunchDarkly is driven by “service connections + client MAU”: 58.33 for a 3-person team with 10 connections/2K MAU, but 6,106.67 at 200 connections/500K MAU; team size does not change the price, while replicas and dev/staging environments do. Unleash is driven by seats: 225 for 3, 750 for 10, 1,500 for 20, plus 235 at 100M requests; cheapest at large teams/high requests, expensive for small teams. Flagsmith is driven by plan + member overage + requests: 90 for 3 on Start-Up; adding a 4th member forces Scale-Up at 250, 10 members 500, 20 members 1,000, plus 4,750 at 100M requests. Statsig is driven by events: unlimited seats, 150 at 2M events, 900 at 20M, 4,900 at 100M; more expensive than Unleash at low events, cheaper than Flagsmith/LaunchDarkly at high events.
| Platform | Main cost driver | Small team | Large team/high usage | Most-missed item |
|---|---|---|---|---|
| LaunchDarkly | Connections + client MAU | 58.33 (10 connections/2K MAU) | 6,106.67 (200/500K) | Replicas, workers, dev/staging count as connections |
| Unleash | Seats + API requests | 225 (3 seats) | 1,735 (20 seats/100M) | 5-seat self-hosted minimum; 5/million after 53M |
| Flagsmith | Plan + member overage + requests | 90 (3 members/2M) | 5,750 (20 members/100M) | 4th member forces Scale-Up; 50/member overage |
| Statsig | Metered events | 150 (2M events) | 4,900 (100M events) | Flag checks are unlimited, but event definitions matter |
Editorial calculation, not a quote. Excludes tax, enterprise, SSO/SCIM, audit, support, implementation and migration; “small/large” refer to the 3/20-person tiers above and are not performance- or feature-equivalent.
Hidden costs: enterprise, SSO, environments, overage, annual billing
None of the four self-serve prices includes full enterprise governance: LaunchDarkly’s SCIM, custom roles, required approvals and unlimited audit are Enterprise (custom quote), and observability/experimentation beyond free allowances are extra; Unleash’s 99.99% SLA, Customer Success and Premium support are Custom Enterprise annual contracts, and self-hosted starts at 5 seats; Flagsmith’s SAML/SSO and governance/audit start at Scale-Up, while Enterprise adds private cloud/self-hosting and 20+ members; Statsig’s SSO, RBAC, warehouse-native and HIPAA are Enterprise, while Pro includes basic approvals and API controls. Also watch monthly premiums (LaunchDarkly monthly is about 20% above annual), environments/replicas, migration and training.
| Item | LaunchDarkly | Unleash | Flagsmith | Statsig |
|---|---|---|---|---|
| SSO/SCIM | Enterprise quote | PAYG includes SSO/SCIM/RBAC/audit (2 years) | Scale-Up includes SAML/SSO | Enterprise |
| Audit/approvals | Foundation has approval requests; required approvals Enterprise | PAYG includes audit/change approvals | Scale-Up includes change/audit | Pro has change approvals; RBAC Enterprise |
| SLA/support | Enterprise quote | 99.9% PAYG; 99.99% annual | Email/chat; Enterprise quote | Pro standard; Enterprise priority |
| Overage | Connections 10 each; MAU 8.33/1K | Requests 5/million | Requests 50/million; members 50 each | Events 50/million |
| Monthly premium | About 20% | None (monthly card) | 12.5%–20% | None (monthly) |

Which option fits which scenario?
3–5 person teams with few connections and low client MAU: LaunchDarkly Foundation, with no seat fee, about 58/month at 10 connections/2K MAU. Stable 10–20 person teams with predictable request volume: Unleash PAYG, 75/seat/month with 53M requests, about 1,735/month at 20 seats/100M. 3–20 people needing SSO/audit without an enterprise contract: Flagsmith Scale-Up, 250/month for 5, 500/month for 10, watching request overage. Teams that want product analytics/experimentation plus flags and many seats: Statsig Pro, 150/month for 5M events with unlimited seats. Enterprise governance/private deployment/99.99% SLA: all four need custom quotes; list required controls before comparing.
| Scenario | First choice | Why | Check first |
|---|---|---|---|
| 3–5 people/few services/low MAU | LaunchDarkly Foundation | No seat fee; from 58/month | Replica/environment connections, MAU |
| 10–20 people/predictable requests | Unleash PAYG | 75/seat, 53M requests included | 5-seat minimum, request peaks |
| 3–20 people/SSO/audit | Flagsmith Scale-Up | From 250/month, 5 members/5M | 50/member overage, request overage |
| Product analytics/experiments | Statsig Pro | 150/month, unlimited seats/flag checks | Event definition, 5M allowance |
| Enterprise governance/private deploy | All four Enterprise | SSO/SCIM/audit/SLA/private cloud | Contract, BAA, residency |
| Many services/replicas | Unleash / Statsig | Connections/seats do not scale with replicas | Request/event volume |

What should procurement and acceptance specify?
At least ten things: team seats, service connections/replicas/environments, client MAU, API requests or events, flag count, SSO/SCIM/audit, approval/change workflow, SLA/support, data residency/compliance, migration/rollback. Run a 30-day POC on real traffic and record SDK requests, connections, MAU, events, flag changes and the bill; do not compare only “price per seat” or “price per million requests”.
- Seats: developers, product, operations; whether billing is per platform user rather than end user.
- Connections: server-side SDKs, replicas, workers, dev/staging; whether averaged over time.
- MAU: unique client users/devices; how anonymous/authenticated users are counted.
- Requests/events: SDK polling, flag checks, experiment exposures, analytics events; definitions and allowances.
- Governance: SSO/SCIM, RBAC, approvals, audit, change history, environment permissions.
- SLA: uptime commitment, support response, incident communication, status page.
- Compliance: data residency, BAA/HIPAA, SOC2/ISO, subprocessors.
- Migration: flag/segment/experiment import/export, SDK replacement, downtime, rollback.
- Contract: annual discount, renewal uplift, overage settlement, seat changes, early termination.
- POC: 30 days of real traffic; record requests/events, connections, MAU, changes and bill variance.
FAQ
What is cheapest for a 10-person team?
At 50 connections/50K MAU/20M requests·events: Unleash 750, LaunchDarkly 858.17, Statsig 900, Flagsmith 1,250 per month. Unleash’s 53M request allowance covers 20M and the seat fee is 750; LaunchDarkly has no seat fee but connections/MAU reach 858; Flagsmith needs 500 in seat fees plus 750 in request overage at 10 members.
What is cheapest for a 3-person team?
At 10 connections/2K MAU/2M requests·events: LaunchDarkly 58.33, Flagsmith 90, Statsig 150, Unleash 225. LaunchDarkly’s 5 free connections + 1K free MAU cover a small team; Unleash at 3 seats is still 225, and self-hosted has a 5-seat minimum.
Why does LaunchDarkly have no seat fee?
Foundation bills service connections and client MAU, not seats; a connection is one server-side SDK connected to one environment, and replicas, workers and dev/staging environments count. It is cheap for large teams with few services and low MAU, and expensive when services/replicas multiply.
Why does Flagsmith jump from 90 to 250?
Start-Up is 40/month for 3 members and 1M requests; the 4th member forces Scale-Up at 250/month for 5 members and 5M requests. At 10 members it is 250 + 5×50 = 500 in seat fees, plus 15M requests × 50/million = 750, for 1,250. The 3-to-5 member step is a plan jump, not linear pricing.
Is a Statsig event the same as a request?
No. Statsig Pro’s 5M allowance is metered events (analytics/experiment exposures, etc.), while flag/config checks are unlimited; Flagsmith/Unleash requests are SDK/API requests. Applying 2M/20M/100M to both is an editorial assumption; recalculate from each vendor’s actual counters during procurement.
What is cheapest at 100M requests/events?
At 20 people/200 connections/500K MAU/100M: Unleash 1,735, Statsig 4,900, Flagsmith 5,750, LaunchDarkly 6,106.67 per month. Unleash’s 53M allowance + 5/million overage is lowest at high volume; Statsig’s 50/million events is above Unleash but below LaunchDarkly’s connection/MAU combination.
What hidden costs should we expect?
Enterprise SSO/SCIM, audit/required approvals, 99.99% SLA, dedicated support, private cloud/self-hosting, BAA/HIPAA, data residency, migration/training, monthly premiums, environments/replicas, and request/event overage. Self-serve prices rarely include these; put each on the quote before signing.
Can we compare only “price per seat”?
No. The four vendors bill connections+MAU, seats+requests, plan+seats+requests and events respectively; the same “10-person team” can differ by 1.7× and the same “100M requests/events” by 3.5×. Use your own 30-day connections, MAU, requests/events and seats in a POC rather than a unit-price table.
Research method and limitations
This article separates “official facts” from “editorial modelling”: LaunchDarkly connection/MAU rates, Unleash seat/request rates, Flagsmith plan/member/request rates and Statsig event rates come from the four US pricing pages (accessed 6 November 2026); the 3/10/20-person, 10/50/200-connection, 2K/50K/500K-MAU and 2M/20M/100M request/event totals are arithmetic on published unit prices, not vendor quotes. It does not compare actual latency, SDK coverage, flag evaluation consistency, failover, migration effort or support quality.
Eight limitations: (1) only US public list prices are used, excluding tax, discounts, private pricing, commitments and regional differences; (2) LaunchDarkly/Flagsmith use annual prices while Unleash/Statsig use published monthly prices, with monthly premiums shown only where published; (3) the meters differ — connections, MAU, API requests and metered events are not interchangeable; (4) 2M/20M/100M means requests for Flagsmith/Unleash, events for Statsig, and has no equivalent at LaunchDarkly; (5) tiers are not feature-equivalent; Flagsmith Start-Up/Scale-Up, Statsig Pro, Unleash PAYG and LaunchDarkly Foundation have different boundaries; (6) enterprise SSO/SCIM/audit/99.99% SLA/private deployment/BAA, implementation, migration, training, observability and experimentation overage are excluded; (7) actual flag evaluation latency, SDK coverage, failover, data residency and support response were not tested; (8) prices and terms can change by contract, region and exchange rate. Treat this as a unit-conversion template and replace assumptions with a 30-day real-traffic POC.
