Featureflip vs ConfigCat
Flat pricing, project ceilings, network-traffic metering, and SSO on free — a 2026 comparison.
Last updated:
Featureflip is the cheaper, project-friendlier alternative to ConfigCat for small teams. Both are flat-priced, focused feature-flag tools — no per-seat, no per-MAU fees. The wedge is plan ceilings: Featureflip Pro is $49/month for 10 projects and unlimited flags; ConfigCat Pro is $110/month for 3 projects and 100 flags. Pick Featureflip if you run multiple apps or want the cheaper paid tier. Pick ConfigCat if you need Rust, Elixir, Unity, Unreal, or edge-runtime SDKs, or longer audit-log retention.

ConfigCat pricing
As of May 13, 2026, sourced from configcat.com/pricing. We re-verify quarterly.
- Forever Free — $0/mo. 2 products, 10 flags, 2 environments, unlimited seats, 20 GB/mo network traffic, 7-day audit log. SSO, SAML, and SCIM included.
- Pro — $110/mo. 3 products, 100 flags, 3 environments, unlimited seats, 100 GB/mo network traffic, 35-day audit log.
- Smart — $325/mo. 10 products, unlimited flags, unlimited environments, 1 TB/mo network traffic, 35-day audit log.
- Enterprise — $900/mo. Unlimited products, 4 TB/mo network traffic, 2-year audit log, 99.99% SLA.
- Dedicated — $4,500/mo. Private cloud, 24 TB/mo network traffic, 2-year audit log.
ConfigCat includes SSO, SAML, and SCIM on every tier — a real advantage for procurement-gated buyers.
Worked example: small team running 3 apps
A team running 3 separate apps (web product, internal admin, mobile), 8 engineers, 12 flags per app (36 flags total):
- Featureflip Pro: $49/mo flat = $588/year. 10-project ceiling, 30-day audit. Fits with room to grow to 10 apps.
- ConfigCat Pro: $110/mo = $1,320/year. Pro caps at 3 products and 100 flags — exactly fits this team, but with no headroom. Adding a 4th app forces Smart at $325/mo = $3,900/year.
At this profile Featureflip Pro is roughly 2.2× cheaper than ConfigCat Pro, and ~6.6× cheaper than ConfigCat Smart when the 4th app ships.
Worked example: solo developer or freelancer
- Featureflip Solo: $0/mo. 1 project, 10 flags, 1 seat.
- ConfigCat Forever Free: $0/mo. 2 products, unlimited seats, 20 GB/mo network traffic.
For freelancers maintaining multiple client projects, ConfigCat's free tier is genuinely more generous (2 products, unlimited seats). Featureflip Solo is optimised for the individual developer on a single side project.
Pricing TL;DR
- Multi-project teams that want the cheapest flat paid tier — Featureflip Pro ($49/mo, 10 projects).
- Solo / freelancer wanting more than 1 project on free — ConfigCat Forever Free (2 products, unlimited seats).
- Procurement requires SSO before purchase — ConfigCat (SSO on every tier, including free).

SDK and platform support
ConfigCat's SDK breadth is wider. Both tools ship JavaScript, Node.js, Python, .NET, Java, Go, PHP, Ruby, React, Swift/iOS, Android, and Flutter — the major server and client surface. ConfigCat additionally ships Rust, Elixir, Kotlin Multiplatform, Unity, Unreal Engine, Bun, Deno, Cloudflare Workers, and C++. Featureflip's official list covers 13 SDKs; ConfigCat's covers roughly 22.
If your stack uses Elixir, Rust, Kotlin Multiplatform, Unity, Unreal, Bun, Deno, or Cloudflare Workers, ConfigCat is the better fit today. Game-development teams in particular should default to ConfigCat for the Unity and Unreal SDK coverage. Featureflip's REST and SSE streaming APIs work from any HTTP-capable runtime, but you write the integration yourself.
See the Featureflip SDK overview for the current supported list.
Where each tool wins
Honest is faster than balanced. Use whichever column matches your situation.
Pick ConfigCat when…
- You need SSO, SAML, or SCIM on day one without paying Enterprise. ConfigCat ships SSO/SAML/SCIM on every tier including the free Forever plan. Featureflip's SSO is Enterprise-only. For procurement teams that gate vendor approval on SSO presence, ConfigCat removes that block at $0/mo.
- Your stack uses Elixir, Rust, Kotlin Multiplatform, Unity, Unreal, Bun, Deno, or Cloudflare Workers. ConfigCat's SDK list is roughly 1.7× wider and covers game development and edge runtimes that Featureflip does not.
- You need long-term audit-log retention. ConfigCat Enterprise retains audit logs for 2 years. Featureflip Business is 90 days.
- You're a freelancer or solo dev with multiple client projects. ConfigCat Forever Free (2 products, unlimited seats) is more generous for that profile than Featureflip Solo (1 project, 1 user).
- You need webhooks for change events. ConfigCat ships webhooks on every tier (1 / 3 / unlimited). Featureflip's webhook support is roadmap.
Pick Featureflip when…
- You want the cheaper paid tier at the same feature surface. Featureflip Pro is $49/mo flat for 10 projects and unlimited flags. ConfigCat Pro is $110/mo for 3 projects and 100 flags. Roughly 2× cheaper at the same usage profile.
- You run multiple apps or expect to. Featureflip Pro includes 10 projects out of the gate. ConfigCat Pro forces a jump to Smart ($325/mo) when you exceed 3 products — a 3× price step.
- You don't want network-traffic accounting. Featureflip evaluations are unlimited on every tier. ConfigCat meters network traffic — a non-issue for most apps, but a hidden cost for chatty client-side apps with high MAU.
- You want real-time SSE streaming, not polling. Featureflip pushes flag changes to SDKs via Server-Sent Events. ConfigCat's default model is polling with webhook-triggered cache invalidation. For kill switches and incident response where seconds matter, SSE is the cleaner model.
- You need native JSON flags. Featureflip supports JSON variations as a first-class flag type. ConfigCat supports string, integer, and double — JSON encodes as a string but loses SDK call-site type-safety.
- You want a modern, focused tool surface. No legacy product clutter, no analytics or observability bundled in. The dashboard does one thing.
Migrating from ConfigCat to Featureflip
Most teams choose at adoption time rather than migrating. If you're switching, here's what changes.
Concept mapping
The core data model translates cleanly. Most flag definitions move 1:1.
| ConfigCat | Featureflip | Notes |
|---|---|---|
| Product | Project | Same concept, different name. Recreate each ConfigCat product as a Featureflip project. |
| User Object | User / context | Context passed per evaluation in both — string, number, boolean attributes. |
| Segment | Segment | 1:1 — recreate via the Featureflip dashboard. |
| Targeting rule | Targeting rule (condition groups) | Featureflip groups conditions with AND/OR operators between groups; condition operators move 1:1. |
| Percentage Option | Percentage rollout | Deterministic-hash bucketing on both sides. |
| String / int / double setting | String / number / JSON variation | Int and double both map to Featureflip's number type. ConfigCat JSON-encoded strings move to native JSON variations. |
Things to plan for
- Prerequisite flags.ConfigCat's parent-child flag dependencies now migrate 1:1 — Featureflip ships first-class variation-match prerequisite flags with cycle detection and a dedicated
PrerequisiteFailedevaluation reason. ConfigCat's "does not equal" comparator inverts to an equivalent "equals" prerequisite during migration. - Stale flag detection works differently.ConfigCat's zombie flags report surfaces flags that haven't been changed or toggled within a configured period. Featureflip's stale flag detection instead classifies every flag-environment as Active, Stale (30 days), or Dead (90 days) from real evaluation traffic, with reasons attached — so a flag that's still toggled occasionally but serves one variation to everyone is caught too. What doesn't migrate is ConfigCat's code-references CLI scan: keep a periodic
grepin CI for finding where each flag is referenced in code. - Audit log retention.Drops from ConfigCat Enterprise's 2 years to Featureflip Business's 90 days. Export ConfigCat logs before migration if you need historical compliance records.
- Webhooks need re-pointing.ConfigCat's webhook payload shape differs from Featureflip's. Integrations consuming flag-change events will need adapter logic or downstream re-wiring. (Featureflip webhooks are roadmap — if you rely on them today, raise this with us at sales@featureflip.io.)
- SDK initialisation changes.Replace
ConfigCatClient.get(sdkKey)withFeatureFlip.init({ sdkKey })at the application entry point. Flag-key strings carry over as-is for most cases.
Frequently asked questions
- Is Featureflip cheaper than ConfigCat?
- At the paid tier, yes. Featureflip Pro is $49 per month flat ($39 per month annual) for 10 projects and unlimited flags. ConfigCat Pro is $110 per month for 3 projects and 100 flags. For multi-project teams Featureflip is roughly 2× cheaper at the same usage profile. On the free tier ConfigCat is more generous for freelancers with multiple client projects — 2 products and unlimited seats, against Featureflip Solo at 1 project and 1 user.
- Does ConfigCat have a project limit and does Featureflip?
- Yes to both, and the limits differ significantly at the paid tier. ConfigCat Pro is capped at 3 products. Featureflip Pro includes 10 projects. The 4th product on ConfigCat forces an upgrade to Smart at $325 per month — Featureflip Pro stays at $49 per month through 10 projects.
- Does Featureflip charge per network traffic or evaluation like ConfigCat?
- No. Every Featureflip plan includes unlimited evaluations and has no network-traffic limit. ConfigCat meters network traffic per tier — 20 GB on Free, 100 GB on Pro, 1 TB on Smart, 4 TB on Enterprise. For most applications the limit is not binding, but high-MAU client-side apps with chatty SDK polling can hit it.
- Does Featureflip include SSO and SAML like ConfigCat does on free?
- Not on the free or Pro tiers. ConfigCat ships SSO, SAML, and SCIM on every tier including their free Forever plan. Featureflip requires the Enterprise plan for SSO/SAML/SCIM. If procurement requires SSO before purchase, ConfigCat is the cheaper path until you cross the project or flag ceiling.
- Does Featureflip support multivariate and A/B testing like ConfigCat?
- Yes. Featureflip supports boolean, string, number, and JSON variations with deterministic-hash percentage rollouts. The bucketing is consistent across sessions and devices, which is the property that makes A/B data analysable. Neither Featureflip nor ConfigCat ships a built-in significance and lift dashboard — both expect you to instrument variation assignment into your own analytics (Mixpanel, Amplitude, your warehouse) and compute results there. LaunchDarkly is the major vendor that bundles the analysis.
- What SDKs do Featureflip and ConfigCat support?
- Heavy overlap on the major server and client surface. Both ship JavaScript, Node.js, Python, .NET, Java, Go, PHP, Ruby, React, Swift/iOS, Android, and Flutter. ConfigCat additionally ships Rust, Elixir, Kotlin Multiplatform, Unity, Unreal Engine, Bun, Deno, Cloudflare Workers, and C++. Featureflip additionally ships a dedicated Browser SDK with first-class React bindings. If your stack uses Rust, Elixir, Unity, Unreal, or a modern edge runtime, ConfigCat is the better fit today.
