A side-by-side editorial comparison of Easy!Appointments and Proposify — release velocity, themes, recent moves, and the top alternatives to consider.
Easy!Appointments 1.6 lands video conferencing, GDPR tools, and a serious security overhaul across its CalDAV and booking stack.
Easy!Appointments, an open-source self-hosted scheduler, is shipping its 1.6 major version through a long pre-release cycle that has introduced Jitsi and Google Meet integration, CAPTCHA and ALTCHA anti-abuse protection, GDPR features, and a rebuilt CalDAV synchronization stack. The 1.6.1 security hardening pre-release then landed a concentrated batch of serious vulnerability fixes: LDAP injection in directory search, SSRF in CalDAV URL handling, cross-account appointment takeover, provider credential exposure to secretary accounts, and CAPTCHA bypass — a set that suggests the expanded surface area of 1.6.0 brought corresponding security debt.
Proposify 3 launches after 2.5 years of development—the platform's first complete architectural reset.
Proposify shipped its v3 platform in May 2025, a ground-up rebuild that reframes the product as a proposal experience layer rather than a document editor. The Q1 2026 update indicates steady post-launch iteration, with the team shipping new integrations and incremental improvements now that the architectural work is done.

The 1.6 release line is expanding Easy!Appointments from a simple booking page into a more complete scheduling platform: video conferencing links, richer calendar sync, GDPR compliance tooling, and hardened multi-provider access controls all move it closer to commercial alternatives. The security work in 1.6.1-beta.1 is as important as the features — self-hosted deployments that serve real customer data need these fixes before anyone should run 1.6 in production.
A stable 1.6.1 release is the next step, clearing the pre-release label once the security fixes are confirmed across the beta testing community. After that, the CalDAV and video conferencing integrations will likely expand — CalDAV push notifications or two-way Google Calendar sync are the natural follow-ons.

The 2.5-year development cycle means v3 is a fundamental platform rewrite. With the foundation in place, Proposify is expanding through vertical-specific integrations (Aspire for field services), broadening the seat model (Collaborator seats for non-sales stakeholders), and building the automation layer that underpins future AI capabilities. The 2024 public API positions Proposify to be embedded in custom sales stacks.
The next phase is AI-assisted proposal drafting—the 2024 automation engine is a natural foundation for AI-generated content components. Competitors PandaDoc and GetAccept shipped AI features during the 2.5-year v3 development window; Proposify needs to close that gap in 2026.
