Comparison
Quonfig vs ConfigCat
ConfigCat is a solid, no-surprises feature flag service: simple flat pricing, unlimited team members on most plans, and one of the broadest SDK lineups around (30+). Quonfig is the git-native choice — every flag is a JSON file in a repo you can clone, changes stream over SSE in about a second, and self-hosting is open from day one. Bottom line: pick ConfigCat for flat-rate simplicity; pick Quonfig when you want to own your config and ship in real time.
Feature matrix
Quonfig vs ConfigCat, feature by feature
An honest side-by-side. A green check is a clear strength, a gray dash is a workable-but-different approach, and a red X is a real gap.
Quonfig SDKs and the seven OpenFeature providers are at 1.0; the qfg CLI is pre-1.0. ConfigCat plan prices reflect their public pricing page and may change — check both vendors for current figures.
Which one
Best for…
Both are good tools. The right pick depends on what you optimize for.
Best for teams who want to own their config and ship changes in real time. Git-native storage, SSE delivery in about a second, nine native SDKs plus OpenFeature, and open self-hosting from the start — ideal when an AI-heavy codebase is creating flags faster than humans retire them.
Best for teams who want dead-simple flat pricing and the widest possible SDK coverage. With 30+ SDKs, unlimited team members on most plans, and predictable per-plan billing, ConfigCat is a reliable, low-overhead choice if config-as-code isn't a requirement.
Git-native storage vs a hosted config store
The core difference is where your config lives. Quonfig stores every workspace as a real git repo — one JSON file per flag — so your change history is git history: a real author, an exact diff, and a timestamp on every change. You clone it with qfg pull or plain git, with no export fees and no lock-in.
ConfigCat keeps your flags in its own hosted store. It exposes a dashboard audit log and a Public Management REST API, which is plenty for most teams — but there's no repo to clone and no config-as-code workflow. When AI agents are generating flag changes, a git-backed trail means every change is already a reviewable commit you can diff, bisect, and revert with tools you know.
Real-time SSE delivery vs interval polling
Quonfig pushes config changes to backend SDKs over SSE in about a second, with ETag caching and a 60-second safety-net poll behind it. Flip a kill switch and your fleet sees it almost immediately — without every process hammering the service on a tight interval.
ConfigCat's SDKs poll on a configurable interval (auto-, lazy-, or manual-polling). That model is simple and reliable, and it caches config for fast local evaluation — but propagation speed is bounded by your poll interval, so a change can take as long as that interval to reach every client. If sub-second propagation of a flag flip matters to you, streaming delivery is the meaningful difference.
Self-hosting and pricing
Quonfig is open-source and self-hostable from the start: run it against a local directory of JSON with no account, or host the full platform yourself. Cloud pricing is usage-based with a public live calculator and free seats — and at scale it runs roughly 10x cheaper than the major platforms.
ConfigCat's strength here is predictability: flat per-plan pricing ($110 / $325 / $900) with unlimited team members on most plans makes the bill easy to reason about. The trade-off is that self-hosting is gated behind its Dedicated tier at roughly $4,500/mo, so on-prem or air-gapped deployments carry a much higher floor than Quonfig's open self-host path.
Side by side
The short version
Where each platform genuinely shines.
- Simple, predictable flat pricing per plan.
- 30+ SDKs — one of the broadest lineups available.
- Unlimited team members on most plans.
- Closed config store — no git repo to clone.
- SDKs poll on an interval, not real-time push.
- Self-hosting only on the ~$4,500/mo Dedicated tier.
- Flags as JSON in a git repo you own and can clone.
- SSE delivery propagates changes in about a second.
- 9 native SDKs + 7 OpenFeature providers.
- Open-source / self-hostable from the start.
- Usage-based pricing, ~10x cheaper at scale.
- Audit trail is git history: author, diff, timestamp.
