Sanity vs Stirling-PDF: at a glance
What is Sanity?
Highest-cadence shipper in view, with agent tooling now a parallel track to the editor
Sanity is releasing across many surfaces at once — Studio, the React App SDK, the MCP server, ecosystem packages, and the Media Library. The standout pattern is a fast-iterating MCP server (multiple versions in this window) that makes the content platform operable by AI agents alongside the usual editor polish.
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.
Sanity vs Stirling-PDF: editorial side-by-side
Sanity
5.0DEVOPS
Highest-cadence shipper in view, with agent tooling now a parallel track to the editor
◆ Current state
Sanity is releasing across many surfaces at once — Studio, the React App SDK, the MCP server, ecosystem packages, and the Media Library. The standout pattern is a fast-iterating MCP server (multiple versions in this window) that makes the content platform operable by AI agents alongside the usual editor polish.
◆ Where it's heading
Two tracks run in parallel: incremental hardening of the human editing experience (Studio search, content releases, media versioning) and rapid buildout of agent-facing tooling (MCP tools for patching, schema deploy, document creation, feedback). Sanity is positioning the same content backend to be driven by both people and agents.
◆ Prediction
Expect the MCP server to keep its rapid release cadence, widening the set of platform operations agents can perform, while Studio and SDK work continues as steady polish.
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.
