Stirling-PDF vs WildFly: at a glance
What is Stirling-PDF?
Stirling PDF's 3.x line ships bulk processing, org-wide signing and fortnightly feature releases
Stirling PDF 3.0 in late September added the PDF Processor for running tools across folders, FTP or S3 sources, optional AI classification and extraction, free OAuth SSO and a free allowance of 1,000 automated PDFs a month. Releases since have arrived about every two weeks: 3.1.0 made group signing (Stirling Sign) default for new users and trialled an embedded Office converter, 3.2.0 replaced the multi-tool with a Page Editor and let password-protected PDFs be used without removing the password, and 3.2.1 and 3.2.2 added viewer and annotation features.
What is WildFly?
WildFly 42 brings virtual threads to Jakarta Concurrency.
WildFly is a Jakarta EE application server on a regular train of Beta, Final and patch releases. WildFly 42.0.0.Final (October 22) supports virtual threads in the Jakarta Concurrency 3.1 implementation, promotes idle time-based eviction for distributable sessions, SFSBs and timers to default stability, and adds automatic meter management for resources added at runtime. 41.0.1 in August was a security patch closing three IIOP CVEs.

◆ Current state
Stirling PDF 3.0 in late September added the PDF Processor for running tools across folders, FTP or S3 sources, optional AI classification and extraction, free OAuth SSO and a free allowance of 1,000 automated PDFs a month. Releases since have arrived about every two weeks: 3.1.0 made group signing (Stirling Sign) default for new users and trialled an embedded Office converter, 3.2.0 replaced the multi-tool with a Page Editor and let password-protected PDFs be used without removing the password, and 3.2.1 and 3.2.2 added viewer and annotation features.
◆ Where it's heading
The product is moving from a self-hosted toolbox to an automation and workflow platform with metered hosted services attached. Feature releases come quickly, with visible regressions fixed in the next point release.
◆ Prediction
Expect Stirling Office Convert to move toward default and native desktop, as the 3.1.0 notes say is planned, plus continued Processor work.
WildFly
5.0DEVOPS
WildFly 42 brings virtual threads to Jakarta Concurrency.
◆ Current state
WildFly is a Jakarta EE application server on a regular train of Beta, Final and patch releases. WildFly 42.0.0.Final (October 22) supports virtual threads in the Jakarta Concurrency 3.1 implementation, promotes idle time-based eviction for distributable sessions, SFSBs and timers to default stability, and adds automatic meter management for resources added at runtime. 41.0.1 in August was a security patch closing three IIOP CVEs.
◆ Where it's heading
WildFly moves features through stability levels release by release; 42 promotes the eviction configuration that first arrived in 39. The bug list also shows continuing cleanup of XML parsing issues (CWE-611) and clustering edge cases.
◆ Prediction
Expect 42.0.1.Final next, consolidating fixes and component upgrades as 41.0.1 did.
