Plans and current product information
Franz lists a free Starter plan for 3 services and one workspace. Its checked pricing page lists Pro at €60 per year, alongside Max and a Lifetime option. These have different feature bundles; the old single $14.99 monthly comparison is not a reliable description of the current offer.
Centrio Free supports up to 3 services. Pro costs €4 monthly or €40 annually. Compare the full payment period, taxes and any separate provider charges rather than approximate exchange rates.
Separate AI requirements from the messaging workspace
Decide whether you only need access to messages or also model-assisted text work. Your own provider key, a local model and an included cloud allowance imply different costs and data flows. Two plans labelled AI do not necessarily provide the same models or quotas.
Test one real workflow: open two accounts, receive a message on the inactive account, draft a reply and return to the original conversation. If AI is not part of your work, judge sign-in, notifications and the cost of the service count you need.
Run the same test in both apps
- Use the same accounts and web pages; verify a new message while the target account is not active. Check sound, badge and the operating-system notification separately.
- Send and receive a small attachment. Open a link outside the app and confirm that it goes to the intended browser or account.
- Restart the app and test after the computer wakes from sleep. A saved session may still expire or be revoked by its service.
- For memory and startup comparisons, record OS, app versions, service count and elapsed time after launch. Measure all related processes with the same workload; idle numbers alone are not a benchmark.
Decide from your actual constraints
Keep Franz if it already completes your essential tasks at an acceptable cost. Test Centrio if its arrangement of services and plan features better fits your work. Neither product can guarantee every feature of a native messenger inside its web version.
