Pricing entry tiers: ConfigCat Feature Flags at Free, Free Blocks at Free. Check each app's tier structure for the capacity limits you actually need before deciding — the headline number is the same shape, but the gating shape per tier (seats, usage volume, integrations) varies.
Recommended evaluation path: install both apps' free tiers (where available) and run them in parallel on a small cohort for 7-14 days before committing. The data tables below show the per-feature breakdown — for most teams the deciding factor will be a single integration or workflow detail that's hard to compare from listing pages alone.
This verdict is generated from the live marketplace data on this page — rating, review count, pricing tier, and category position all refresh from the canonical Slack Marketplace listing every 24 hours. AppRanks does not accept payment to influence comparison outcomes; the methodology is documented on the About page and applies identically to every pair on the site.

Both ConfigCat Feature Flags and Free Blocks offer paid plans only. ConfigCat Feature Flags starts at Free; Free Blocks starts at Free. Compare the per-tier features in the Pricing section above before committing.
AppRanks cannot recommend one over the other from published marketplace data: the Slack Marketplace does not expose a rating or review base that separates them. Read both apps' detail pages for the feature breakdown, and compare against your own requirements rather than a headline number.
Both apps are one-click installs from the Slack Marketplace. AppRanks doesn't measure setup time directly, and the Slack Marketplace publishes no review base that would let us infer it for these two — read the recent reviews on each app's detail page for user-reported install experience.
ConfigCat Feature Flags typically suits early-stage and growth-mode teams based on its published review base (0 reviews). Free Blocks typically suits early-stage and growth-mode teams based on its published review base (0 reviews). A larger review base generally means the app has been exercised at scale — relevant if you are processing high volume or handling enterprise compliance requirements.
Migration support varies by app and category. ConfigCat Feature Flags and Free Blocks both publish their export options on their marketplace listing pages (or in their support docs); some apps offer one-click import from competitors, others require CSV. The fastest check: search "import from Free Blocks" in each app's help center. AppRanks does not track migration tooling directly — this is a category-specific capability worth verifying before commitment.
