ConfigCat
ConfigCat is a bootstrapped Budapest feature flag service with open-source SDKs, unlimited seats on every plan, and published prices from a free tier to a $4,500-a-month dedicated cloud, used by teams such as Speechify.
Small and mid-size software teams that want feature flags, percentage rollouts, and user targeting across many languages, with a flat monthly price that does not grow with headcount or traffic from end users.
Product teams that want built-in A/B test statistics and warehouse-native experiment analysis, and buyers who need a large vendor with a long list of enterprise reference accounts.
Verdict
ConfigCat does the core job of a feature flag service well: targeting by user attribute, percentage rollouts, and SDKs for most major languages, at prices anyone can read before a sales call. Unlimited seats on every plan is a real advantage over tools that bill by user. It is thin on experimentation analysis, so teams that want to measure test results will need a second tool. For straightforward flag management, it is an easy recommendation.
Score Breakdown
These scores cover how well ConfigCat handles flag targeting and rollouts, how wide its SDK and platform coverage is, how much experimentation and analysis it offers, and how clear its pricing is, and then how it does as a company on innovation, communication, pricing, and contract terms.
Who Uses ConfigCat, Where It Fits on Price, and Its Competitors
ConfigCat's customers include Speechify, Modsy, FieldAware, and ControlPoint. Most use it to separate feature releases from code deployments, turn features on for chosen user groups, and roll changes out by percentage. The product offers open-source SDKs for .NET, Java, Android, iOS, Python, and other platforms, a hosted or on-premise option, and integrations with common developer tools. ConfigCat was started in 2018 by three former colleagues in Budapest, got its first paying customer in 2019, and has not raised outside funding.
On price, ConfigCat has a Forever Free plan and paid plans at $110, $325, and $900 a month, with a Dedicated private cloud at $4,500 a month. Annual billing saves up to 10%. Its closest competitors are Unleash, Flagsmith, GrowthBook, and Statsig.

How Well ConfigCat Fits Each Feature Flag Use Case
We rated ConfigCat against the situations teams bring to a feature flag vendor, drawing on its pricing, product, and team pages and on its own account of how the company started.
| Use case | Fit | Notes |
|---|---|---|
| Gradual and percentage rollouts | Strong | Targeting covers region, email, subscription, and any custom user attribute. |
| Large teams on a budget | Strong | Every plan, including the free one, allows unlimited seats. |
| Polyglot codebases | Strong | Open-source SDKs cover the major back-end, web, and mobile platforms. |
| A/B testing with statistics | Weak | ConfigCat serves variants, but buyers need a separate analytics tool to read results. |
| Self-hosting or private cloud | Mixed | On-premise and Dedicated options exist, but they start at $4,500 a month. |
| Very high-traffic mobile apps | Mixed | Pricing follows config downloads, so heavy client traffic can push a team up a tier. |
Review Excerpts
These excerpts come from customer quotes ConfigCat publishes on its site, which the company chose, and from the buyer concern we found in its pricing and product pages. Paid reviews and pay-for-play sites were excluded.
“We went from no feature flags to using them very heavily in our backend, and have started to integrate them with some of our front-end internal tools to facilitate quick and safe deployments.”
“Aside from the amazing customer support we've received over the years, ConfigCat has made it super easy for new engineers to easily configure and launch our tests.”
“Flags were easy, but when we wanted to know which variant won, we still had to wire the results into our analytics tool ourselves.”
