Plain built an autonomous support agent, and has now built the controls to trust it.
A side-by-side editorial comparison of INKY and osTicket — release velocity, themes, recent moves, and the top alternatives to consider.
INKY is wiring an LLM into email security while binding itself tighter to Kaseya.
INKY ships a dashboard release every one to two weeks, moving from 1.8.5 to 1.9.5 since May. The functional center is the Triage workspace, which pulled detection review, message actions and account-takeover enforcement into one place and made ATO configurable without a SIEM. July added Smart Insights, an LLM second opinion on inbound mail, plus automatic Autotask ticketing. Running alongside the security work, email-signature management has grown from a single page in June into a tabbed editor with per-field styling.
osTicket runs in steady maintenance mode — security patches and PHP compatibility, little net-new
osTicket's release feed is pure maintenance. The recent stable line (v1.18.x) ships security updates, bug fixes, and ongoing PHP 8.3/8.4 compatibility, with refreshed language packs and plugins each time. Release cadence is slow and irregular — the latest, v1.18.4, followed v1.18.3 by roughly five months. This is a mature open-source helpdesk being kept current, not actively reinvented.

Two threads are pulling in the same direction. Detection is becoming AI-assisted and explainable, with Smart Insights returning a verdict, a trickiness rating and a written rationale rather than a score. And the managed-service channel is being deepened at every layer — Autotask billing, Autotask ticketing, Kaseya-provisioned entitlements, a third-party training platform slotted in as an option. INKY is optimizing for the provider reselling it across many tenants, not the employee reading the mail.
Smart Insights is gated to Pro with a per-team opt-out, which points to it being extended and monetized further rather than made universal. Mesh was added as a recognized upstream provider under an auto-detect setting, so additional relay providers are the obvious continuation of that work.

The throughline is keeping a long-lived codebase safe and runnable on current PHP, plus the multi-year push to get installs onto OAuth2/Modern Authentication as Microsoft and Google retire Basic Auth for email. Expect continued patch-and-compatibility releases rather than feature expansion; the project's value is stability and self-hostability, and the changelog reflects that posture.
The next release will most likely be another v1.18.x maintenance drop with security fixes and PHP/library compatibility, timed to a disclosed vulnerability or a new PHP version. A feature-led release isn't indicated by this history.
