What is Docker?

Docker Desktop is steadily layering AI tooling — Gordon, MCP Toolkit, Model Runner — onto the developer experience.

Docker Desktop is on weekly release cadence with three threads: (1) Gordon, Docker's AI assistant, gained persistent local memory across sessions and contextual command-failure hints; (2) the MCP Toolkit is maturing — community server OAuth, profile template cards, an onboarding tour, and warnings for unverified community servers; (3) the new unified Logs view continues hardening in beta with CLI hints and Compose-stack filtering. Engine, Compose, and Buildx are all moving forward on point releases. RHEL 8 support is ending, with installs requiring RHEL 9 or 10 in the next release.

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.

Docker Desktop is steadily layering AI tooling — Gordon, MCP Toolkit, Model Runner — onto the developer experience.

◆ Current state

Docker Desktop is on weekly release cadence with three threads: (1) Gordon, Docker's AI assistant, gained persistent local memory across sessions and contextual command-failure hints; (2) the MCP Toolkit is maturing — community server OAuth, profile template cards, an onboarding tour, and warnings for unverified community servers; (3) the new unified Logs view continues hardening in beta with CLI hints and Compose-stack filtering. Engine, Compose, and Buildx are all moving forward on point releases. RHEL 8 support is ending, with installs requiring RHEL 9 or 10 in the next release.

◆ Where it's heading

Two clear arcs. First, Docker Desktop is positioning itself as an AI-native dev environment — Gordon as the in-IDE assistant, Model Runner for local model serving, MCP Toolkit as the agent integration plane, dhi CLI for Hardened Images. Second, the platform is doing the unglamorous work that retains paying users: a unified Logs view, OAuth/login bug fixes, ECI hardening, and steady Compose v5.x maturation.

◆ Prediction

Expect Gordon to add cross-session task continuation and tighter MCP Toolkit integration, and the Logs view to leave beta within the next two releases now that filtering and CLI hints are in place. RHEL 9/10-only support will likely be followed by similar pruning on other older distro lines.

S6.3

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.
