The short version
- Only Insomnia has a free tier, so it costs nothing to try first.
- Each has a real cost: Insomnia git Sync on the free tier covers up to 3 users only; Kameleoon no rate card is published. Reported entry pricing around several hundred euros a month for the limited prompt-based tier comes from third parties rather than Kameleoon, so any budget you build before contacting sales is a guess.
- They diverge on capability: Insomnia covers REST API Client, Kameleoon covers Visual A/B test editor.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Insomnia
- Git Sync on the free tier covers up to 3 users only
- Mock servers are capped at 1,000 requests a month on free, then $10 per 25,000
- Role-based access control requires Pro at $12 per user per month
- SSO, SCIM and vault integrations are Enterprise only at $45 per user per month
- Working without an account is limited to the local-only Scratch Pad
Kameleoon
- No rate card is published. Reported entry pricing around several hundred euros a month for the limited prompt-based tier comes from third parties rather than Kameleoon, so any budget you build before contacting sales is a guess.
- Web experimentation, feature experimentation and personalisation are licensed as separate capabilities, so the unified platform story costs materially more than the entry configuration most buyers are first quoted.
- The partner and agency ecosystem is concentrated in France and continental Europe; a buyer in North America or Asia will find fewer implementation specialists and less community knowledge than for Optimizely or VWO.
- The integration catalogue is smaller than the market leaders, so a stack built on less common analytics or CDP tooling may need custom work that a larger vendor would cover natively.
- Client-side visual testing still carries the structural problems of the approach, including performance cost and single-page-application fragility; the anti-flicker engine reduces the symptom but does not remove the dependency on the DOM staying stable.
