Fourwaves vs FreeSWITCH
A side-by-side editorial comparison of Fourwaves and FreeSWITCH — release velocity, themes, recent moves, and the top alternatives to consider.
Fourwaves vs FreeSWITCH: at a glance
What is Fourwaves?
A daily drip of conference-platform polish, with finance filtering and attendee self-service leading.
Fourwaves ships small, single-line changes to its academic conference platform on an almost daily rhythm, publishing each under a bare date. The recent window splits three ways: organization-admin finance tooling, where transactions can now be filtered by organization and by payment gateway; attendee self-service, including a sidebar listing entries already submitted and the ability to add presentations to a personal agenda from the session list; and a run of navigation and consistency fixes. No single change reshapes the product.
What is FreeSWITCH?
With the legacy purge done, FreeSWITCH spent 1.11.2 bounds-checking everything that parses bytes
FreeSWITCH shipped 1.11.2 in August 2026, three months after the 1.11.0 branch cut that removed roughly thirty modules and migrated the regex engine to PCRE2. Where 1.11.0 was about deleting surface area, 1.11.2 is about auditing what remains: nearly every bug line is a bounds or length check in a parser — STUN attributes, base64 decode, XML entity decoding, RTMP H.264 NAL units, XML-RPC WebSocket frames, MSRP body lengths. Alongside the fixes it adds an interface allowlist and turns on DTLS client-certificate verification against the SDP fingerprint plus opt-in STUN MESSAGE-INTEGRITY checks on inbound ICE. The build system continues moving off self-hosted infrastructure onto GitHub-published artifacts and upstream packages.

Fourwaves
5.0MEETINGS
A daily drip of conference-platform polish, with finance filtering and attendee self-service leading.
◆ Current state
Fourwaves ships small, single-line changes to its academic conference platform on an almost daily rhythm, publishing each under a bare date. The recent window splits three ways: organization-admin finance tooling, where transactions can now be filtered by organization and by payment gateway; attendee self-service, including a sidebar listing entries already submitted and the ability to add presentations to a personal agenda from the session list; and a run of navigation and consistency fixes. No single change reshapes the product.
◆ Where it's heading
The work concentrates where operators running many events feel friction — untangling payments that arrive through shared gateways, and cutting how much attendees must re-enter across registration and submission forms. A parallel thread smooths the event-day surface, with a live-and-upcoming session panel and consistent back links, icons, and headings across detail pages. Fixes and features are interleaved continuously rather than gathered into releases, so the cadence reads as steady maintenance with incremental reach.
◆ Prediction
Expect more of the same two increments — transaction visibility for organizations running events across shared gateways, and reducing what attendees must re-enter — rather than a headline capability.
FreeSWITCH
2.5MEETINGS
With the legacy purge done, FreeSWITCH spent 1.11.2 bounds-checking everything that parses bytes
◆ Current state
FreeSWITCH shipped 1.11.2 in August 2026, three months after the 1.11.0 branch cut that removed roughly thirty modules and migrated the regex engine to PCRE2. Where 1.11.0 was about deleting surface area, 1.11.2 is about auditing what remains: nearly every bug line is a bounds or length check in a parser — STUN attributes, base64 decode, XML entity decoding, RTMP H.264 NAL units, XML-RPC WebSocket frames, MSRP body lengths. Alongside the fixes it adds an interface allowlist and turns on DTLS client-certificate verification against the SDP fingerprint plus opt-in STUN MESSAGE-INTEGRITY checks on inbound ICE. The build system continues moving off self-hosted infrastructure onto GitHub-published artifacts and upstream packages.
◆ Where it's heading
The 1.11.x line reads as a deliberate two-step: cut the maintenance surface, then harden what is left. Having removed thirty modules, the project can now afford to audit the media and signaling paths line by line, and the pattern of fixes — untrusted length fields reaching memory writes — suggests a systematic pass rather than incremental reports. The parallel thread is dependency modernization: mod_v8 moved from a custom v8-6.1 fork to upstream libnode, SpanDSP and libvpx were bumped, and Windows builds now pull pre-compiled FFmpeg and libcodec2 rather than building them. Both threads point the same direction — less bespoke code to own.
◆ Prediction
Expect the hardening pass to continue into the remaining parsers, with the opt-in STUN MESSAGE-INTEGRITY check becoming default once operators have shipped through a release. The build-system migration off files.freeswitch.org appears partway done, so the next release likely finishes moving the remaining assets to GitHub-hosted artifacts.
