How to choose the right replacement, compared honestly on price, runtime and fit.
Last updated:
LaunchDarkly is the most capable feature-management platform on the market, and for many teams, the most expensive. If you are reading this, you are probably staring at a renewal quote or a per-service-connection bill that grew with your infrastructure. Here are six credible alternatives, what each is genuinely best at, and where it falls short. We include our own product, ShipSilently, and we will tell you plainly when one of the others is the better choice.
Teams routinely report 10–20% step-ups, and being pushed off favourable legacy plans onto current pricing at renewal. Vendr lists a median LaunchDarkly contract around $72k/year.
Foundation bills ~$12 per service connection, effectively per pod or VM. Autoscaling microservices inflate the bill; one public case went from ~$10k to ~$45k/year.
Client-side billing is ~$10 per 1,000 monthly active contexts, so cost climbs with user growth, the success you are paying to enable.
LaunchDarkly is now flags + experimentation + observability. Many teams want just flags, and dislike that Enterprise and Guardian pricing is quote-only.
| Tool | Entry price | Pricing model | At scale |
|---|---|---|---|
| ShipSilently | $49/mo flat | Flat, unlimited seats, 10M evals | Stays flat; cheap overage |
| ConfigCat | ~$110/mo (Pro) | Flat, tiered by configs/downloads | Steps up by download volume |
| Flagsmith | $45/mo (Start-Up) | Per-request + seat caps | Climbs with requests & seats |
| Unleash | $0 self-host · $75/seat Cloud | Per-seat (hosted) or self-host | Linear per seat, or your ops |
| Statsig | $0 free · $150/mo (Pro) | Flags free; analytics events metered | Scales with event volume |
| GrowthBook | $0 self-host · usage Cloud | Open source + warehouse-native | You run it, or Cloud usage |

It depends on why you are leaving. For flat, predictable pricing, ShipSilently or ConfigCat. For open source / self-host, Flagsmith or Unleash. For experimentation depth, Statsig or GrowthBook. There is no single "best", match the alternative to the pain.
For flags-only usage, Statsig can be $0 (flags are free under its analytics tier) and ShipSilently is a flat $49/mo with no per-connection or per-MAU metering. Self-hosting Flagsmith or Unleash is $0 in licence but costs infrastructure.
Flagsmith (BSD-3) and Unleash (AGPL-3.0) have mature self-host stories; GrowthBook is also open source. LaunchDarkly itself is not truly self-hostable, and ShipSilently is managed-only today (self-host is on its 2027 roadmap).
Statsig has the closest experimentation depth (CUPED, sequential testing), with GrowthBook strong for warehouse-native analysis. Pure flag tools like ShipSilently and ConfigCat do not aim to replace the stats engine.
Flagging concepts map closely across tools (projects→environments, flags→flags, targeting→targeting). Most teams export flags via the LaunchDarkly REST API and recreate them. Experimentation data does not transfer; keep LaunchDarkly running for in-flight tests.
