Passbolt vs Slack

Passbolt vs Slack: at a glance
What is Passbolt?
Passbolt collapsed the Community-to-Pro upgrade into a settings toggle, then spent the next release on sharing transparency.
Three releases on a roughly monthly cadence, each named after a song. 5.12 took the Safari extension out of beta so it stands level with Chrome, Firefox and Edge, and added a PIN code resource type. 5.13 built on the 5.12 codebase unification to let administrators switch between Community and Pro editions from organisation settings, with no separate environment or manual migration. 5.14 added explicit confirmation dialogs before creating items in shared folders or editing shared resources, made group members visible in access lists, and fixed an MFA policy enforcement issue.
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.

◆ Current state
Three releases on a roughly monthly cadence, each named after a song. 5.12 took the Safari extension out of beta so it stands level with Chrome, Firefox and Edge, and added a PIN code resource type. 5.13 built on the 5.12 codebase unification to let administrators switch between Community and Pro editions from organisation settings, with no separate environment or manual migration. 5.14 added explicit confirmation dialogs before creating items in shared folders or editing shared resources, made group members visible in access lists, and fixed an MFA policy enforcement issue.
◆ Where it's heading
Two threads are running at once. Commercially, the friction between the open-source edition and the paid one has been engineered away — evaluation is now a toggle rather than a deployment project. Product-wise, the focus has moved from storing secrets to showing users who can actually reach them, which is where self-hosted password managers usually lose enterprise deals. Both threads point at the same buyer: an admin at an organisation already running Community and considering Pro.
◆ Prediction
The sharing-visibility work looks unfinished — expect access review or permission audit surfaces to follow — and the in-app edition switch is a natural place for licence and trial handling to appear next.

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.
