WildFly vs Zed
A side-by-side editorial comparison of WildFly and Zed — release velocity, themes, recent moves, and the top alternatives to consider.
WildFly vs Zed: at a glance
What is WildFly?
WildFly's first 41.x patch is a security release, with three IIOP CVEs closed at once
WildFly runs a steady train: a Beta, a .0.Final, then a patch release that consolidates fixes and component upgrades. WildFly 41 arrived in July with OIDC scope and request-object support promoted out of preview. The first patch on that line is dominated by security — three CVEs in the IIOP stack covering unauthenticated class loading, a missing-authentication path on the NameService, and a pre-auth denial of service on the listener — plus a long run of dependency upgrades that resolve further advisories.
What is Zed?
Zed 1.26 adds Pyrefly for Python and debugs WebAssembly from the JavaScript debugger.
Zed 1.26.2 adds Pyrefly as an optional built-in Python language server, an expandable variable tree in debugger hovers and DWARF support so the JavaScript debugger can step through WebAssembly sources. Agent work continues in smaller pieces: ACP configuration defaults now apply only to new conversations, model pickers get better fuzzy search, and thinking controls explain when thinking can't be turned off. The previous week's 1.25 line shrank binaries and gave external ACP agents context compaction.

◆ Current state
WildFly runs a steady train: a Beta, a .0.Final, then a patch release that consolidates fixes and component upgrades. WildFly 41 arrived in July with OIDC scope and request-object support promoted out of preview. The first patch on that line is dominated by security — three CVEs in the IIOP stack covering unauthenticated class loading, a missing-authentication path on the NameService, and a pre-auth denial of service on the listener — plus a long run of dependency upgrades that resolve further advisories.
◆ Where it's heading
The releases show the split personality of a mature application server: feature work concentrates in the Beta and .0.Final, while the .1 patch exists to move CVE fixes and component versions to users quickly. The recurring theme across 40.x and 41.x is that the ageing edges of the platform — IIOP, the OIDC client, container base images — are where the risk keeps surfacing, and each patch prunes a little more. WildFly 40.0.1 used the same slot to move container images to JDK 25 and drop JDK 17.
◆ Prediction
Expect a 42 Beta to open the next feature cycle while 41.x continues absorbing component upgrades and advisory fixes on the same patch cadence.
Zed
5.0DEVOPS
Zed 1.26 adds Pyrefly for Python and debugs WebAssembly from the JavaScript debugger.
◆ Current state
Zed 1.26.2 adds Pyrefly as an optional built-in Python language server, an expandable variable tree in debugger hovers and DWARF support so the JavaScript debugger can step through WebAssembly sources. Agent work continues in smaller pieces: ACP configuration defaults now apply only to new conversations, model pickers get better fuzzy search, and thinking controls explain when thinking can't be turned off. The previous week's 1.25 line shrank binaries and gave external ACP agents context compaction.
◆ Where it's heading
Zed is splitting attention between its agent panel, where ACP agents keep gaining the same session handling as Zed's own, and core editor depth in languages and debugging. Weekly stable releases with community-contributed features and quick model additions remain the pattern.
◆ Prediction
Expect 1.27 next week with more ACP session and model-picker work, plus further debugger and language-server additions.
