The short version

  • Only ConfigCat has a free tier, so it costs nothing to try first.
  • Each has a real cost: ConfigCat there is no experimentation or statistical analysis engine, so teams wanting real A/B tests with significance testing must buy and integrate a separate analytics or experimentation product.; Very Good Security vGS sits in the live path of every request carrying sensitive data, so its latency and availability become yours, and an outage in the proxy is a payment outage no matter how healthy your own systems are.
  • They diverge on capability: ConfigCat covers Feature flags and configuration, Very Good Security covers Aliasing proxy.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

  • A team that wants every engineer, product manager and support agent to have a login without paying per seatnot Very Good Security
  • Decoupling deployment from release with percentage rollouts and a kill switch, without buying an experimentation platformnot Very Good Security

Very Good Security

  • A marketplace facing its first PCI DSS Level 1 assessment that wants to keep card data off its own estate rather than harden a dozen servicesnot ConfigCat
  • A merchant negotiating with a second acquirer that needs card credentials portable so the negotiation is real rather than theoreticalnot ConfigCat
  • A fintech collecting bank account and identity documents that wants sensitive fields absent from logs, backups and analytics warehouses by constructionnot ConfigCat
  • A card issuer that must display a full PAN in its own mobile app without the app or its backend touching cardholder datanot ConfigCat

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ConfigCat

  • There is no experimentation or statistical analysis engine, so teams wanting real A/B tests with significance testing must buy and integrate a separate analytics or experimentation product.
  • Pricing by flag count punishes exactly the hygiene you want: the Pro tier caps at 100 flags, so teams that do not aggressively retire stale flags are pushed to the 325 dollar Smart tier for housekeeping reasons rather than growth.
  • The free tier allows only 2 environments, which does not cover the common development, staging and production split, so almost any real deployment starts on a paid plan.
  • It is a smaller vendor than the category incumbents, so enterprise procurement teams will find less depth in compliance attestations, contractual terms and reference architecture than LaunchDarkly offers.
  • Flag evaluation relies on SDK-side caching of a CDN-delivered config, which is fast but means propagation of a change is eventually consistent rather than instant, something to understand before relying on it as an emergency kill switch.

Very Good Security

  • VGS sits in the live path of every request carrying sensitive data, so its latency and availability become yours, and an outage in the proxy is a payment outage no matter how healthy your own systems are.
  • Token portability is the whole selling point yet leaving VGS means migrating tokens back out, a project the vendor has no incentive to streamline, so the lock-in you removed from your acquirer partly moves to VGS.
  • Entry pricing at around one thousand US dollars a month is real money for a pre-revenue fintech, and it buys volume-limited throughput, so cost scales with exactly the growth that made you buy it.
  • Scope reduction is not scope elimination: your QSA still assesses how you integrate, and teams regularly discover that a support tool or an internal admin screen pulled plaintext back in and dragged systems into scope again.
  • Proxy-based interception constrains how you design request flows, and non-standard payloads, streaming uploads or binary formats often need custom routing rules that make debugging production issues noticeably harder.

Answered from the vendors’ own pages

ConfigCat: How is ConfigCat priced?

By feature flag, environment and product count. Seats, monthly active users and flag reads are unlimited on every plan.

Very Good Security: Does VGS make me PCI compliant?

No. It removes cardholder data from your systems so your assessment covers a far smaller boundary, but you still complete an assessment and your integration is part of it.

ConfigCat: Is the free tier usable?

For small projects yes, but at 10 flags and 2 environments it will not cover a dev, staging and production setup.

Very Good Security: Can I move to another processor without re-collecting cards?

Yes, that is a core reason people buy it. The vault reveals stored credentials to whichever processor you route to.

ConfigCat: Can it run A/B tests?

It can split traffic, but there is no statistics engine. You need a separate analytics tool to decide a winner.

Very Good Security: What does it cost?

Published entry pricing is about one thousand US dollars per month; growth and enterprise tiers are quoted.

ConfigCat: How fast does a flag change take effect?

SDKs poll and cache, so changes propagate on the polling interval rather than instantly.

Very Good Security: Is it only for card data?

No. The proxy handles any sensitive field, including bank details, national identifiers and documents, though payments is where the product is now focused.
