Pros & Cons
Inboxen
Pros
Fully open source and self-hostable under AGPL-3.0
Strong privacy-first design philosophy, including data deletion on shutdown
AGPL license guarantees the code stays open even in hosted derivatives
No cost beyond your own server to run an instance
Development continues actively on Codeberg despite the original hosted service closing
Cons
The original public hosted instance at inboxen.org has shut down, so there is no ready-to-use hosted option
Requires real self-hosting skills in Python, Django, PostgreSQL and server administration
No official mobile apps
Smaller community and support base than commercial alias services like SimpleLogin
Documentation is developer-oriented rather than consumer-friendly
Freepbx
Pros
Core software is completely free and open source with no license fees
Backed by Sangoma, a publicly traded company, giving it long-term development stability rare among open-source projects
Powers over a million installations, meaning extensive community documentation, forums, and third-party expertise are available
Can run on modest, inexpensive hardware for small deployments
Optional commercial modules and PBXact give a clear upgrade path to professional support without forcing it on free users
Cons
Requires Linux system administration knowledge to install, secure, and maintain
Officially supported only on Debian Linux, limiting deployment flexibility for other distributions
Some genuinely useful features, like advanced endpoint management, are gated behind paid commercial modules
Telephony and VoIP configuration (SIP trunks, NAT traversal, codecs) has a steep learning curve for non-specialists
No official cloud-hosted SaaS version directly from the FreePBX project itself, requiring self-hosting or a third-party host
Use Cases
Inboxen

Freepbx
Small business phone systems — IT administrators deploy self-hosted FreePBX servers to run a full-featured business phone system without per-user SaaS licensing fees.
Managed service provider deployments — MSPs and telecom integrators deploy and support FreePBX or PBXact systems for multiple client businesses using Sangoma hardware and commercial modules.
Home-lab and hobbyist telephony — Telecom hobbyists run FreePBX on inexpensive hardware to learn VoIP administration or manage a personal or small-office phone system.
