Stirling-PDF vs Auth0
Side-by-side trajectory, velocity, and editorial themes.
Stirling-PDF deepens real signing and lays MCP groundwork on a fast V2 cadence
Stirling-PDF is in a heavy release cadence on its V2 line, alternating substantive minors with rapid hotfixes. The last month shipped desktop hardware-token signing (PKCS#11/smart-card and OS cert stores), a work-in-progress MCP page, JDK 25 enforcement, and large merge-memory improvements, punctuated by Postgres and desktop-signing hotfixes.
Two threads stand out: deepening real document signing (hardware tokens, shared signing, cert-store integration) and laying agent-facing groundwork via an MCP page and automation-oriented backend work. The team is also steadily reworking the V2 file-management UI that users found clunky. This is a self-hosted PDF tool maturing toward serious signing and automation use.
Expect the MCP page to move from WIP toward a usable agent interface, and the signing feature set to broaden beyond desktop-only.
Auth0's cadence is all enterprise plumbing: federation, SCIM provisioning, session governance.
Auth0 is shipping steadily against enterprise B2B identity rather than consumer login. The recent run clusters around federated session control (IPSIE session_expiry), bidirectional SCIM provisioning, refresh-token lifecycle management, and directory sync across Okta, OIDC, and Google Workspace connections. Login-UX touches like Google One Tap are the exception, not the theme.
The direction is standards alignment and closing federation gaps, not net-new product categories. Inbound and outbound SCIM, IPSIE claim support, and granular refresh-token endpoints all point at Auth0 becoming the control plane for enterprise provisioning and session lifetime, the surface where Okta and WorkOS set the bar.
Expect more IPSIE profile coverage and continued SCIM/Event Streams expansion, with the outbound provisioning template a likely candidate to graduate from Early Access to GA.
