Split vs ConfigCat
Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Free tierWhat drives the bill
The metric that actually scales your invoice.
Paid tiers are quote-based, priced by monthly tracked keys.
Plans run Free, Pro $110, Smart $325, Enterprise $900 and Dedicated $4,500 a month. Unlimited seats and unlimited flag reads on every plan, including free — unusual and genuinely valuable for wide access; paid tiers mainly raise flag, environment and product limits.

Strengths
- Automatic metric impact on every flag catches regressions nobody thought to measure.
- Guardrail alerts stop a bad rollout before it reaches everyone.
- Strong data-platform integrations.
- Unlimited team members at every tier, so product and support can toggle flags too.
- Very simple to adopt — an afternoon, not a project.
- Broad SDK coverage including Dart and Elixir.
Limitations
- Post-acquisition roadmap now sits inside Harness's broader platform strategy.
- Requires meaningful event instrumentation before the impact analysis is useful.
- Opaque enterprise pricing.
- No experimentation or analytics to speak of.
- Limited targeting sophistication compared to LaunchDarkly.
- Small vendor.
Best for
Teams that want every release measured, not just deliberate experiments.
