Converse.js vs FluentBooking: at a glance
What is Converse.js?
Converse.js 14 lands OMEMO:2 — the browser XMPP client catches up on modern encryption.
Converse.js reached 14.0.0 in June 2026 after a tight beta train, and the release is defined by one thing: support for OMEMO:2, the current revision of XMPP's end-to-end encryption. The surrounding work is all encryption ergonomics — per-chat encryption state remembered across chat-close and re-login, an explicit error surfaced for undecryptable messages instead of silently dropping them, the toggle hidden on untrusted devices, and original filenames preserved on encrypted image download. New PubSub API methods for create, subscribe and unsubscribe round out the release.
What is FluentBooking?
FluentBooking opens bookings to AI agents via MCP, then ships workflow ergonomics
FluentBooking shipped MCP support in 2.4.0, enabling AI assistants to query, book, and reschedule through existing team permissions. Version 2.5.0 follows immediately with operational ergonomics: private notes, in-place rescheduling, form prefilling. The product has been on a fast cadence — major version every 2–4 weeks — with a full admin redesign (2.3.0) and an external security review (2.2.5) showing simultaneous investment in UX and platform reliability.

Converse.js 14 lands OMEMO:2 — the browser XMPP client catches up on modern encryption.
◆ Current state
Converse.js reached 14.0.0 in June 2026 after a tight beta train, and the release is defined by one thing: support for OMEMO:2, the current revision of XMPP's end-to-end encryption. The surrounding work is all encryption ergonomics — per-chat encryption state remembered across chat-close and re-login, an explicit error surfaced for undecryptable messages instead of silently dropping them, the toggle hidden on untrusted devices, and original filenames preserved on encrypted image download. New PubSub API methods for create, subscribe and unsubscribe round out the release.
◆ Where it's heading
The project is closing the gap between having encryption and having usable encryption. Almost every OMEMO change in this cycle is about failure modes users previously had to guess at: a silently dropped message, an encryption toggle offered where it cannot work, an abandoned bundle that never self-healed. That is the work a client does when its encryption is no longer a demo but something people depend on daily. Dropping client-compress for native browser APIs points the same way — fewer bundled dependencies in a security-sensitive path.
◆ Prediction
Expect the 14.x line to settle into interoperability fixes as OMEMO:2 meets other XMPP clients in the wild, with the new PubSub API the most likely base for the next feature layer.

FluentBooking opens bookings to AI agents via MCP, then ships workflow ergonomics
◆ Current state
FluentBooking shipped MCP support in 2.4.0, enabling AI assistants to query, book, and reschedule through existing team permissions. Version 2.5.0 follows immediately with operational ergonomics: private notes, in-place rescheduling, form prefilling. The product has been on a fast cadence — major version every 2–4 weeks — with a full admin redesign (2.3.0) and an external security review (2.2.5) showing simultaneous investment in UX and platform reliability.
◆ Where it's heading
The MCP integration positions FluentBooking as a booking layer that AI orchestrators can call into, not just a standalone scheduler. Combined with the FluentCRM connection in 2.2.0 and the broader Fluent* plugin ecosystem, this is building toward a composable SMB stack where AI can automate scheduling workflows end-to-end. The admin redesign and security hardening signal the product is moving from feature-shipping into operational quality maturation.
◆ Prediction
The MCP foundation is likely to carry more AI-driven automation next: proactive rescheduling, conversational booking flows, or AI-generated availability summaries. FluentCRM integration will probably deepen as the next growth lever given its appearance two versions before the MCP release.
