Testing
Feature flags tied to a metrics pipeline that attributes production impact to each release, now Harness FME

The short version
- Only Convert has a free tier, so it costs nothing to try first.
- Each has a real cost: Convert pricing is driven by monthly tested users, starting at $399 per month for 100,000 monthly tested users on Growth and $599 on Pro; Split split is now a module of the Harness platform and split.io redirects to harness.io, so buying it means entering a Harness commercial relationship rather than a standalone flag vendor contract.
- They diverge on capability: Convert covers A/B testing, Split covers Feature flags with targeting.
- Prices and features above were last checked on 2 September 2026.

What people use each for
The jobs each tool is most often brought in to do.
Convert
- A/B and multivariate testing for conversion optimizationnot Split
- Full-stack experimentation on web and mobilenot Split
- Sequential testing and statistical confidence trackingnot Split
Split
- A product organisation that wants every release measured against conversion and latency by default, not only deliberate experimentsnot Convert
- Running A/B tests with real statistical significance rather than comparing two dashboard linesnot Convert
- Catching a regression at five per cent rollout because a guardrail metric fires before the change reaches everyonenot Convert
- A team already committed to Harness for CI and CD that wants flags in the same platform and contractnot Convert
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Convert
- Pricing is driven by monthly tested users, starting at $399 per month for 100,000 monthly tested users on Growth and $599 on Pro
- Single Sign-On requires the Pro plan at $599 per month
- Multivariate testing, multi-page testing, full stack and feature flags, sequential testing and raw test data export are all withheld from the Growth plan
- Phone support, change history and guided onboarding require Pro
- The advertised $299 and $420 per month rates require paying the full year up front at $3,588 or $5,040
- The Enterprise plan is price on request, is only available as an annual plan, and its data segregation feature carries additional costs
- Listed prices exclude VAT, GST and other taxes, which are added at checkout
- Above 5 million monthly tested users there is no published rate
Split
- Split is now a module of the Harness platform and split.io redirects to harness.io, so buying it means entering a Harness commercial relationship rather than a standalone flag vendor contract.
- Harness no longer publishes per-module prices, so an organisation that wants only feature management cannot get a list price and must negotiate a module out of a platform bundle.
- The measurement engine needs traffic volume to reach significance, so a product with modest usage gets flags with an experimentation layer it will rarely be able to conclude anything from.
- Metric attribution depends on correctly instrumented events flowing into Split, which is an integration project in its own right; without it you have paid for an experimentation platform and are using it as a flag switch.
- As part of a larger DevOps suite the roadmap now competes with CI, CD, security and cloud cost modules for attention, so feature management is no longer the company’s single focus the way it was as an independent product.

Questions people ask
- Is Convert or Split better?

Answered from the vendors’ own pages
Convert: What is the starting price for Convert?
The Growth plan starts at $399/month (or $299/month billed annually for 25% savings) with 100K monthly tested users, 5 projects, and 5 active experiences per project.
SourceSplit: Is Split still called Split?
It is now sold as Harness Feature Management and Experimentation after the Harness acquisition, and split.io redirects to harness.io.
Convert: What is the difference between Growth and Pro plans?
Both cap at 100K tested users/month, but Pro ($599/month or $420/month annual) adds 30 active projects (vs 5), unlimited experiences per project (vs 5), unlimited domains (vs 10), multivariate testing, full-stack testing, sequential testing, and phone support.
SourceSplit: Can I buy just feature flags?
Not from a price list. Harness publishes bundle tiers and directs single-module buyers to sales.
Convert: How much does the Enterprise plan cost?
Enterprise pricing is available 'on request.' It supports 1M+ monthly tested users (12M+ annually), unlimited projects, experiences, and domains, plus dedicated account manager and custom terms.
SourceSplit: What does it do that a plain flag service does not?
It attributes changes in your product metrics to specific flags with statistical significance testing and alerts on guardrail metrics.
Convert: What is the cost to exceed my monthly tested user limit?
Growth overages cost $399 per 100K additional users. Pro/Enterprise overages cost $699 per 250K additional users. Customers can also upgrade mid-cycle at any time.
SourceSplit: Do we need a lot of traffic?
Yes. Statistical tests need volume to conclude, so low-traffic products get limited value from the measurement layer.
