The short version

  • 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.; Osano the published visitor ceilings are low, with the paid self-serve tier stopping around 30,000 monthly visitors, so any consumer facing site with real traffic leaves published pricing immediately and negotiates a quote with no public anchor.
  • They diverge on capability: ConfigCat covers Feature flags and configuration, Osano covers Consent banner.
  • 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.

ConfigCat

  • A consumer or mobile app with millions of users where per-MAU flag pricing would cost more than the flags are worthnot Osano
  • A team that wants every engineer, product manager and support agent to have a login without paying per seatnot Osano
  • Decoupling deployment from release with percentage rollouts and a kill switch, without buying an experimentation platformnot Osano
  • A small team that needs ten flags permanently and can run indefinitely on the free tiernot Osano

Osano

  • A mid market company selling into the EU and California that needs one banner honouring different consent rules by visitor regionnot ConfigCat
  • A privacy counsel who wants a vendor that will contractually stand behind its consent product rather than disclaim all liabilitynot ConfigCat
  • A marketing team that needs Google Consent Mode signals wired correctly so analytics and ads degrade rather than break when consent is refusednot ConfigCat
  • A company with a handful of brand domains wanting one consent record and one scanning schedule across all of themnot 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.

Osano

  • The published visitor ceilings are low, with the paid self-serve tier stopping around 30,000 monthly visitors, so any consumer facing site with real traffic leaves published pricing immediately and negotiates a quote with no public anchor.
  • The no fines guarantee is bounded and conditional on configuring the product as instructed, so it is a marketing differentiator with an indemnity cap rather than the insurance policy the name suggests, and the limits should be read before it influences a decision.
  • Everything beyond consent, including subject rights automation, data mapping and vendor monitoring, is enterprise quoted, so the transparent pricing that attracts buyers covers only the cheapest part of the platform.
  • Tag blocking depends on tags being loaded through the mechanisms Osano can intercept, and marketing teams that inject scripts directly into templates or through server side tagging routinely leak trackers past the banner without anyone noticing.
  • It is a privacy platform rather than a security compliance one, so organisations that also need SOC 2 or ISO 27001 evidence collection run it alongside a separate tool and duplicate parts of the vendor and asset inventory.

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.

Osano: Does the free tier include the no fines guarantee?

No. The guarantee attaches to paid use of the consent product, and the free tier is capped at one domain and 5,000 monthly visitors.

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.

Osano: How is Osano priced?

By monthly website visitors, number of domains and tier. The self-serve path stops at a low visitor ceiling and everything above is quoted.

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.

Osano: Can it handle US state privacy laws as well as GDPR?

Yes, with region aware rule sets covering GDPR, ePrivacy and the US state regimes, so an EU visitor sees an opt-in banner and a US visitor sees the applicable opt-out.

ConfigCat: How fast does a flag change take effect?

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

Osano: Does Osano do subject access requests?

Yes, but in the enterprise tier rather than the published plans, and it is quoted separately from consent.
