Deep Dive: Switching from Sejda Web to Stirling PDF
Trade-offs, installation & data architecture
What you trade away
It closely matches Sejda's browser toolbox, but the user must install a desktop build or operate a local server before the privacy benefit exists.
How to deploy Stirling PDF
Install the native Windows/macOS desktop build, run the Linux JAR, or deploy the documented Docker image/Compose stack; a hosted cloud edition also exists
What it takes to run
The native desktop app is simple, but a full private cross-platform service and automation setup is most reliably deployed with Docker
Where your data lives
Desktop and self-hosted deployments process files on the user's machine/server and can use mounted local storage; the cloud edition uploads files for transient server processing
Why fork Stirling PDF instead of vibe-coding a Sejda Web clone?
The core loop is small enough for a capable coding agent to produce a useful local version in one sitting. For Sejda Web, perform a practical set of PDF edits and conversions in a local browser app. The hard boundary is excellent pdf operations, hosted convenience, desktop app, and edge-case handling, plus document fidelity, identity, and compliance.
