Wire vs Slack
Side-by-side trajectory, velocity, and editorial themes.
Wire keeps its secure web client steady: call quality, MLS reliability, accessibility
Wire is an end-to-end-encrypted messaging and calling app; this feed tracks its web client's production releases. When notes are published they show consistent work on call quality (enhanced audio processing now on by default), real-time reliability (WebSocket recovery and MLS epoch-mismatch handling enabled by default), in-conversation search, accessibility, and Collabora document editing. A large share of the release tags, however, carry no notes at all.
The direction is incremental hardening of a security-focused collaboration client — better calls, more reliable sync and MLS group state, document collaboration via Collabora, and E2EI certificate management. There is no directional pivot here; the arc is reliability, accessibility, and polish for secure-comms and enterprise users.
Expect continued call-quality and MLS reliability work plus deeper Collabora document integration; no single large feature is signaled in the current releases.
Slack is quietly rebuilding itself as a runtime for third-party agents.
Slack's developer platform has shifted its center of gravity from bots-that-reply to agents-that-act. The last month is dominated by agent primitives: apps can now receive the context a user is looking at, Slackbot can call external tools over MCP, and a dedicated agent messaging surface ships alongside steady CLI and Block Kit work.
Each release fills in a piece of an agent platform — context in, tools out, and a native place for agents to converse. Block Kit is gaining richer primitives (containers, data visualization) that read as the display layer for agent output. Three CLI releases in a month show the tooling keeping pace with the expanding surface.
Expect the next moves to connect these pieces: agent context feeding MCP tool calls, and Block Kit's new blocks becoming the standard way agents render results in-channel.
