Stirling-PDF vs Technitium DNS Server: 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 Technitium DNS Server?
Technitium adds LDAP sign-in to the DNS server that already gained SSO in v15.
Technitium DNS Server has shipped eleven v15 releases since April, from v15.0 with OpenID Connect single sign-on to v15.6.2 on October 17. v15.5 in September added LDAP authentication and a zone file editor in the web console, and nearly every release since has carried fixes for reported security issues. Announcements are short and point to the CHANGELOG for detail.

◆ 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.
Technitium DNS Server
5.0DEVOPS
Technitium adds LDAP sign-in to the DNS server that already gained SSO in v15.
◆ Current state
Technitium DNS Server has shipped eleven v15 releases since April, from v15.0 with OpenID Connect single sign-on to v15.6.2 on October 17. v15.5 in September added LDAP authentication and a zone file editor in the web console, and nearly every release since has carried fixes for reported security issues. Announcements are short and point to the CHANGELOG for detail.
◆ Where it's heading
The v15 line keeps extending admin identity, from OIDC to SSO scopes to LDAP, while patch releases arrive every one to two weeks with security fixes. That frequency of reported security issues is the thread to watch.
◆ Prediction
More v15.6.x service updates are likely; whether a v16 line follows is unclear from the feed.
