osTicket vs Sleekplan
Side-by-side trajectory, velocity, and editorial themes.
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.
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.
Sleekplan bets its relaunch on feedback that triages itself
After a quiet stretch through most of 2025, Sleekplan re-accelerated with a June rebuild — Sleekplan 2.0 in beta — pairing a ground-up admin app with an AI layer meant to manage feedback automatically. Alongside it, a rebuilt, fully configurable Impact Score replaces the old black-box prioritization.
The direction is autonomous feedback handling: less manual triage, more AI-driven scoring, routing, and loop-closing, with integrations like Linear pushing items straight into engineering workflows. Making the Impact Score transparent and configurable signals Sleekplan knows teams won't trust automation they can't audit.
Expect Sleekplan 2.0 to move from beta to general availability with the AI layer expanded, plus more two-way integrations that push scored feedback directly into delivery tools.
