NATS vs Zed
A side-by-side editorial comparison of NATS and Zed — release velocity, themes, recent moves, and the top alternatives to consider.
NATS vs Zed: at a glance
What is NATS?
NATS 2.15.2 closes auth-callout and leafnode ACL gaps on both supported lines.
NATS shipped 2.15.2 and 2.14.9 together on Oct 26, the first patches since 2.15.1 went final. Both carry the same fixes: auth callout now respects allowed connection types, leafnode ACLs no longer implicitly allow $MQTT.> permissions, OCSP responses are bound to the certificate serial, and restored v1 snapshots are bounds-checked. Both also move to Go builds that distrust eMudhra intermediates.
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.
NATS vs Zed: editorial side-by-side
NATS
5.0DEVOPS
NATS 2.15.2 closes auth-callout and leafnode ACL gaps on both supported lines.
◆ Current state
NATS shipped 2.15.2 and 2.14.9 together on Oct 26, the first patches since 2.15.1 went final. Both carry the same fixes: auth callout now respects allowed connection types, leafnode ACLs no longer implicitly allow $MQTT.> permissions, OCSP responses are bound to the certificate serial, and restored v1 snapshots are bounds-checked. Both also move to Go builds that distrust eMudhra intermediates.
◆ Where it's heading
After 2.15's desired-state metalayer, the release stream has turned to hardening: two rounds of metalayer data-safety fixes in 2.15.1, now a batch of authorization and certificate-validation fixes. Every 2.15 patch is mirrored to 2.14, so the project is carrying two lines in parallel while 2.15 adoption grows.
◆ Prediction
Expect paired 2.15.3 / 2.14.10 candidates within a few weeks, continuing the mirrored cadence. The entries don't show when 2.14 support ends.
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.
