Miniflux vs Slack
A side-by-side editorial comparison of Miniflux and Slack — release velocity, themes, recent moves, and the top alternatives to consider.
Miniflux vs Slack: at a glance
What is Miniflux?
A minimal RSS reader that made passkeys the only way in, then went back to polishing the reading experience.
Miniflux ships a release roughly monthly, and the 2.2.19-through-2.3.1 stretch was almost entirely security work: OIDC token signature verification, PKCE state cleanup, SHA1 replaced with HMAC-SHA256 for Google Reader API auth, an OAuth account-binding vulnerability, an open redirect, and a possible SQL injection in dynamically built ORDER BY clauses. The two most recent releases return to product — full-text search on PostgreSQL's websearch_to_tsquery, an expanded API v1, and feed language detection.
What is Slack?
Slack is shipping its developer platform to coding agents, not only to developers.
The developer changelog runs two tracks at once. One is a routine modernization wave across the client libraries: Bolt for JS reached v5, the Node SDK packages took coordinated major versions, and the CLI shipped twice in ten days. The other is newer and smaller in volume but larger in intent, aimed at AI tooling rather than at people writing apps by hand.

A minimal RSS reader that made passkeys the only way in, then went back to polishing the reading experience.
◆ Current state
Miniflux ships a release roughly monthly, and the 2.2.19-through-2.3.1 stretch was almost entirely security work: OIDC token signature verification, PKCE state cleanup, SHA1 replaced with HMAC-SHA256 for Google Reader API auth, an OAuth account-binding vulnerability, an open redirect, and a possible SQL injection in dynamically built ORDER BY clauses. The two most recent releases return to product — full-text search on PostgreSQL's websearch_to_tsquery, an expanded API v1, and feed language detection.
◆ Where it's heading
Two threads run in parallel. The security thread has systematically closed off every authentication path that was not cryptographically strict, culminating in 2.3.0 restricting WebAuthn login to discoverable passkeys only. The product thread is API-shaped: entry ID pagination, bulk starred updates, tag filtering, and a Go client that now exposes the full feed record — all aimed at people driving Miniflux from other software rather than its own UI.
◆ Prediction
The API surface is the area with visible momentum, so the next release most likely extends filtering or bulk operations further. Whether the passkey-only stance loosens to accommodate post-password MFA is the open question these notes raise but do not answer.

6.3COMMSCOLLAB
Slack is shipping its developer platform to coding agents, not only to developers.
◆ Current state
The developer changelog runs two tracks at once. One is a routine modernization wave across the client libraries: Bolt for JS reached v5, the Node SDK packages took coordinated major versions, and the CLI shipped twice in ten days. The other is newer and smaller in volume but larger in intent, aimed at AI tooling rather than at people writing apps by hand.
◆ Where it's heading
The MCP and Skills plugin is the clearest signal of where this is going: Slack is packaging its own platform knowledge for consumption by coding agents, and naming Claude Code and Cursor as the first targets rather than shipping a generic endpoint. Meanwhile the SDK work is clearing debt that would get in the way, dropping axios for native Fetch, removing the deprecated Workflow Steps from Apps feature, and raising the Node floor to 20. Modern runtime, fewer legacy surfaces, then agent access on top.
◆ Prediction
The plugin ships for two named agent clients today, so the obvious next step is broadening that list or folding the skills into the CLI itself. The entries do not indicate whether Slack intends the MCP server to reach runtime app behaviour or stay a build-time developer aid.
