LobeHub vs Stalwart
A side-by-side editorial comparison of LobeHub and Stalwart — release velocity, themes, recent moves, and the top alternatives to consider.
LobeHub vs Stalwart: at a glance
What is LobeHub?
LobeHub turned its chat client into an agent operator that delegates to Claude Code and Codex.
Five weeks of weekly releases moving in one direction. CAO, the Chief Agent Operator, turns short exchanges into agents that check their own work, decide the next step and continue without prompting, pausing only when a decision genuinely needs a person. Agent Gateway moved agent execution to the server with WebSocket streaming and session resume across disconnects. Server-side human approval landed for agent actions, alongside a personalised Daily Brief and Notion-style document history. Most recently, coding agents themselves became delegable: Claude Code and Codex are created and controlled from inside LobeHub on desktop, with agent-grouped topics and a Review tab aggregating bulk git diffs. Model and provider additions ride along each release.
What is Stalwart?
Stalwart is shipping email's next-generation auth stack while the specs are still in draft.
Stalwart is an all-in-one mail and collaboration server — SMTP, IMAP, JMAP, CalDAV, CardDAV and WebDAV in one binary — releasing every one to two weeks on the 0.16.x line. The last two months read as a standards campaign: DKIM2 and the full DMARCbis set in 0.16.12, VAPID push in 0.16.14, FreeBSD support in 0.16.13, and a run of IMAP extensions (UIDONLY, UIDBATCHES, MESSAGELIMIT/SAVELIMIT) in 0.16.17. Between the additions, most of each release is JMAP conformance repair driven by the jmap-test-suite.

◆ Current state
Five weeks of weekly releases moving in one direction. CAO, the Chief Agent Operator, turns short exchanges into agents that check their own work, decide the next step and continue without prompting, pausing only when a decision genuinely needs a person. Agent Gateway moved agent execution to the server with WebSocket streaming and session resume across disconnects. Server-side human approval landed for agent actions, alongside a personalised Daily Brief and Notion-style document history. Most recently, coding agents themselves became delegable: Claude Code and Codex are created and controlled from inside LobeHub on desktop, with agent-grouped topics and a Review tab aggregating bulk git diffs. Model and provider additions ride along each release.
◆ Where it's heading
The client is becoming a control plane rather than a chat window. Server-side execution, session resume, human approval gates and self-directed agents are the components of something that runs work while nobody is watching — and delegating to Claude Code and Codex means LobeHub is not trying to be the best coding agent, it is trying to be where you supervise the ones that exist. The Review tab reads that way too: diff review is a supervision surface, not an authoring one.
◆ Prediction
Expect more third-party agents to become delegable alongside Claude Code and Codex, and the approval flow to extend into the coding-agent path where reviewing a diff is the natural gate.
Stalwart
5.0COMMS
Stalwart is shipping email's next-generation auth stack while the specs are still in draft.
◆ Current state
Stalwart is an all-in-one mail and collaboration server — SMTP, IMAP, JMAP, CalDAV, CardDAV and WebDAV in one binary — releasing every one to two weeks on the 0.16.x line. The last two months read as a standards campaign: DKIM2 and the full DMARCbis set in 0.16.12, VAPID push in 0.16.14, FreeBSD support in 0.16.13, and a run of IMAP extensions (UIDONLY, UIDBATCHES, MESSAGELIMIT/SAVELIMIT) in 0.16.17. Between the additions, most of each release is JMAP conformance repair driven by the jmap-test-suite.
◆ Where it's heading
The project is building toward being the reference implementation of the modern mail stack — JMAP first, with the classic protocols held at parity rather than left behind. The fix lists have shifted in character over these eight releases: less "feature does not work", more "spec detail is wrong", which is what a codebase looks like as it converges on conformance. Security and multi-tenancy fixes keep appearing alongside the protocol work, indicating real deployments are exercising the newer subsystems.
◆ Prediction
The next releases most likely track revisions to the drafts already implemented — DKIM2, JMAP push and the calendar drafts are all still moving — rather than adding another protocol surface. Expect continued JMAP conformance fixes until the test suite stops producing them.
