osTicket vs Plain: at a glance
What is osTicket?
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.
What is Plain?
Plain built an autonomous support agent, and has now built the controls to trust it.
Plain's changelog is dated entries with no titles, and nearly all of it concerns two AI surfaces: Ari, the customer-facing responder, and Sidekick, the internal agent. Sidekick spent July gaining reach — its own full-page home, reusable workspace skills, and connection to arbitrary MCP servers. The newest release turns to Ari and adds what was missing around it: a way to test it before customers see it, provenance behind each answer, configurable tone, and explicit escalation rules.

◆ Current state
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.
◆ Where it's heading
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.
◆ Prediction
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.
Plain
8.8SUPPORT
Plain built an autonomous support agent, and has now built the controls to trust it.
◆ Current state
Plain's changelog is dated entries with no titles, and nearly all of it concerns two AI surfaces: Ari, the customer-facing responder, and Sidekick, the internal agent. Sidekick spent July gaining reach — its own full-page home, reusable workspace skills, and connection to arbitrary MCP servers. The newest release turns to Ari and adds what was missing around it: a way to test it before customers see it, provenance behind each answer, configurable tone, and explicit escalation rules.
◆ Where it's heading
The sequence reads as capability first, then governance. Plain rebuilt Ari into an agentic first responder, opened Sidekick to any MCP server, and let teams write skills the whole workspace shares — all of which widen what the agents can do and reach. The current release closes the loop the other way, making that autonomy inspectable and bounded before it is switched on. That is the order support-AI vendors have to complete in: teams will not put an agent in front of customers on capability claims alone.
◆ Prediction
With testing and provenance in place, the next step is likely measurement — resolution and escalation rates per skill, or per-answer quality review feeding back into the skills teams write. The entries are short summaries linking off-site, so per-release depth is limited.
