Elasticsearch vs Stirling-PDF
A side-by-side editorial comparison of Elasticsearch and Stirling-PDF — release velocity, themes, recent moves, and the top alternatives to consider.
Elasticsearch vs Stirling-PDF: at a glance
What is Elasticsearch?
One Node.js Brotli bug and a compromised CA bundle force ten patches across the Elastic Stack.
Elastic shipped 8.19.24, 9.4.9 and 9.5.6 on November 3 with a batch of advisories from ESA-2026-229 to ESA-2026-238. Most trace to two inherited components: a Brotli decoder flaw in the bundled Node.js runtime (CVE-2026-111497) that reaches Kibana, Maps Server, Heartbeat and Elastic Agent Synthetics, and a root store that still trusts eight eMudhra intermediates with leaked keys. Two Elastic-owned denial-of-service bugs, in APM Server's OTLP/HTTP intake and two phonetic encoders, round out the release.
What is Stirling-PDF?
Stirling PDF plans to drop LibreOffice for its own converter within two weeks
Stirling PDF 3.0 in late September added the PDF Processor for bulk jobs, optional AI and free OAuth SSO. Releases since have come about every two weeks: group signing by default in 3.1.0, a Page Editor in 3.2.0, viewer and annotation work in 3.2.x. 3.3.0 lets users pick the beta Stirling Office Convert in many more tools and adds Windows ARM64, lighter mobile scanning and caching.

◆ Current state
Elastic shipped 8.19.24, 9.4.9 and 9.5.6 on November 3 with a batch of advisories from ESA-2026-229 to ESA-2026-238. Most trace to two inherited components: a Brotli decoder flaw in the bundled Node.js runtime (CVE-2026-111497) that reaches Kibana, Maps Server, Heartbeat and Elastic Agent Synthetics, and a root store that still trusts eight eMudhra intermediates with leaked keys. Two Elastic-owned denial-of-service bugs, in APM Server's OTLP/HTTP intake and two phonetic encoders, round out the release.
◆ Where it's heading
Elastic's recent feed is dominated by patch trains: each security batch fans one inherited flaw out across Kibana, Agent, Heartbeat and the Docker images. The newest item is a third-party community tool announced in the feed, not an Elastic release, so product direction beyond the 8.19 / 9.4 / 9.5 maintenance lines is not visible here.
◆ Prediction
Expect further advisories as Node.js and base-image fixes keep flowing into the Synthetics and Kibana images; the entries do not show whether Elastic will stop bundling its own Node.js root store.
Stirling-PDF
5.0DEVOPS
Stirling PDF plans to drop LibreOffice for its own converter within two weeks
◆ Current state
Stirling PDF 3.0 in late September added the PDF Processor for bulk jobs, optional AI and free OAuth SSO. Releases since have come about every two weeks: group signing by default in 3.1.0, a Page Editor in 3.2.0, viewer and annotation work in 3.2.x. 3.3.0 lets users pick the beta Stirling Office Convert in many more tools and adds Windows ARM64, lighter mobile scanning and caching.
◆ Where it's heading
The project is replacing third-party dependencies with its own components. 3.3.0 says Office Convert should become the default next week and LibreOffice should be removed the week after, which would shrink the install and change conversion results for every user.
◆ Prediction
Expect Office Convert to become the default converter in the next release, then LibreOffice removed, as 3.3.0's notes lay out. Conversion bug reports will decide whether that schedule holds.
