Directus vs Stirling-PDF
A side-by-side editorial comparison of Directus and Stirling-PDF — release velocity, themes, recent moves, and the top alternatives to consider.
Directus vs Stirling-PDF: at a glance
What is Directus?
Directus is staging a 12.0 major built on a reworked versioning model and tighter operational defaults
Directus is running its stable 11.17.x line while cutting release candidates for a 12.0 major. The 11.17 releases are a steady stream of editor UX, asset-caching, and AI-endpoint improvements; the 12.0 RCs carry the breaking changes that define the next major.
What is Stirling-PDF?
Stirling-PDF layers MCP and metered AI tools onto its OSS PDF utility, plus a SaaS tier.
Stirling-PDF is shipping fast on its V2 line. The last month splits between heavy engineering — JDK 25 enforcement, a new JPDFium path cutting merge/split memory use by up to 99%, server-side folder storage, desktop multi-window — and a newer direction: an MCP integration page plus pay-as-you-go AI document tools, with stirling.com's SaaS code now folded into the OSS repo. A reworked file-management UI (files left, tools right) addresses long-standing complaints about V2's 'forced file management.' Releases are frequent and several are explicitly flagged WIP.

Directus is staging a 12.0 major built on a reworked versioning model and tighter operational defaults
◆ Current state
Directus is running its stable 11.17.x line while cutting release candidates for a 12.0 major. The 11.17 releases are a steady stream of editor UX, asset-caching, and AI-endpoint improvements; the 12.0 RCs carry the breaking changes that define the next major.
◆ Where it's heading
Two clear threads: incremental product polish in 11.17 (token-field confirmation, ETag/asset revalidation, structured-object AI endpoint, image-editor and list-view UX) and a 12.0 reset of core models — content versioning renamed from main to published, collection status replaced by an archived boolean, and operational defaults like authenticated, cached, multi-instance-shared health checks.
◆ Prediction
Expect more 12.0 release candidates consolidating the versioning and collection-settings changes with backward-compat shims before a stable 12.0, while AI endpoints (structured-object generation) keep expanding in parallel.
Stirling-PDF
6.3DEVOPS
Stirling-PDF layers MCP and metered AI tools onto its OSS PDF utility, plus a SaaS tier.
◆ Current state
Stirling-PDF is shipping fast on its V2 line. The last month splits between heavy engineering — JDK 25 enforcement, a new JPDFium path cutting merge/split memory use by up to 99%, server-side folder storage, desktop multi-window — and a newer direction: an MCP integration page plus pay-as-you-go AI document tools, with stirling.com's SaaS code now folded into the OSS repo. A reworked file-management UI (files left, tools right) addresses long-standing complaints about V2's 'forced file management.' Releases are frequent and several are explicitly flagged WIP.
◆ Where it's heading
Two arcs are visible in the entries. One is performance and desktop maturity: memory, JDK, multi-window, an auto-updater. The other, newer one is monetizable AI — an MCP page and PAYG-gated AI document and 'AI Create' tools, alongside a SaaS/OSS split the team says it will clarify in coming releases. Stirling-PDF is positioning to be both a self-hosted utility and a hosted, AI-assisted service.
◆ Prediction
Expect the MCP page and AI document tools to move from WIP toward shipped, billed features, and clearer OSS-vs-SaaS release notes as the team separates the two products.
