OpenWrt vs Technitium DNS Server: at a glance
What is OpenWrt?
Two stable branches, and the release cadence is now set by CVE disclosure.
OpenWrt is maintaining 24.10 in security-only mode with end of life projected for September 2026, while 25.12 — released in March 2026 after more than a year and over 4,700 commits — carries active development. Nearly every release in the last five months is driven by vulnerability response: a Trail of Bits audit of OpenWrt's own components in February produced four CVEs in umdns, jsonpath and procd, and the odhcpd DHCPv6 server has since yielded a critical stack overflow plus use-after-free and memory disclosure bugs. The 25.12 release itself replaced opkg with apk and was named for Dave Täht.
What is Technitium DNS Server?
A self-hosted DNS server that grew an enterprise identity layer.
Technitium shipped its v15 line in April 2026 and has been iterating on it steadily since, with four point releases in under three months. The defining change was Single Sign-On via OpenID Connect, and nearly every release after it has gone back to sand down that same surface — SSO scopes, SSO implementation fixes, new Settings options. Release notes are thin pointers to a CHANGELOG file, so the granular detail lives outside the feed.
OpenWrt vs Technitium DNS Server: editorial side-by-side
OpenWrt
2.5DEVOPS
Two stable branches, and the release cadence is now set by CVE disclosure.
◆ Current state
OpenWrt is maintaining 24.10 in security-only mode with end of life projected for September 2026, while 25.12 — released in March 2026 after more than a year and over 4,700 commits — carries active development. Nearly every release in the last five months is driven by vulnerability response: a Trail of Bits audit of OpenWrt's own components in February produced four CVEs in umdns, jsonpath and procd, and the odhcpd DHCPv6 server has since yielded a critical stack overflow plus use-after-free and memory disclosure bugs. The 25.12 release itself replaced opkg with apk and was named for Dave Täht.
◆ Where it's heading
The project is being audited seriously for the first time in a while, and it shows — the security sections of these notes have shifted from upstream dependency updates to defects in OpenWrt's own daemons. That is uncomfortable in the short term and healthy in the long term, and the pattern of same-day paired releases across both branches shows the maintainers treat the installed base as production infrastructure rather than hobbyist firmware. Device support continues accreting steadily underneath, mostly mediatek filogic and ramips targets.
◆ Prediction
Expect the 24.10 branch to receive security-only patches until the September 2026 EoL and then stop, with migration pressure toward 25.12 increasing in the notes. Further odhcpd findings are plausible given how much of the recent CVE volume traces to that one daemon.
Technitium DNS Server
2.5DEVOPS
A self-hosted DNS server that grew an enterprise identity layer.
◆ Current state
Technitium shipped its v15 line in April 2026 and has been iterating on it steadily since, with four point releases in under three months. The defining change was Single Sign-On via OpenID Connect, and nearly every release after it has gone back to sand down that same surface — SSO scopes, SSO implementation fixes, new Settings options. Release notes are thin pointers to a CHANGELOG file, so the granular detail lives outside the feed.
◆ Where it's heading
The work is consolidating around administration and access control rather than DNS resolution itself. A self-hosted DNS server adding OIDC and scope configuration is positioning for multi-admin and organizational deployments, not the single-operator homelab it started in. The steady cadence of small Settings additions suggests configuration surface is being expanded on user request rather than to a fixed roadmap.
◆ Prediction
Expect continued hardening of the SSO path and more granular Settings options in the v15.x line. The entries don't indicate what a v16 would contain.
