Alternatives to Stirling PDF
Self-hosted web PDF toolbox
Stirling PDF ranks #10 of 13 in PDF tools, with an Alt Score of 68. It is licensed under MIT, open source with paid hosting from $0.01/PDF processed and available on the web. 8 of 10 checklist rows are verified against a public source.
Individuals, IT teams, and organizations (including regulated industries like healthcare, legal, and government) who need to handle PDFs without relying on cloud services or paid proprietary tools.
A single web app bundling 50+ PDF tools: merge, split, convert, compress, rotate, watermark, add/remove password protection, redact, OCR, and edit metadata. It runs entirely on infrastructure you control, so files never leave your server. Available as an open-source, self-hosted deployment or a hosted/commercial option.
Deploy the application via Docker (or another self-hosted setup) on your own server, then use the browser-based interface to upload a PDF, pick an operation from the toolset, and download the processed file.
