What is Knock?
Knock plants its flag across every major AI platform: Claude, ChatGPT, Codex, and Cursor all get native connectors
Knock is a developer notification infrastructure platform that has rapidly deployed native connectors to Claude, ChatGPT, Codex, and Cursor in under two weeks. Alongside the AI integrations, it shipped Amplitude as a data source for triggering workflows, custom roles and permissions for enterprise access control, and an analytics interface within its own Knock Agent. Slack integration has deepened with threaded replies and internal channel support.
What is Skipper?
Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.
Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

Knock plants its flag across every major AI platform: Claude, ChatGPT, Codex, and Cursor all get native connectors
◆ Current state
Knock is a developer notification infrastructure platform that has rapidly deployed native connectors to Claude, ChatGPT, Codex, and Cursor in under two weeks. Alongside the AI integrations, it shipped Amplitude as a data source for triggering workflows, custom roles and permissions for enterprise access control, and an analytics interface within its own Knock Agent. Slack integration has deepened with threaded replies and internal channel support.
◆ Where it's heading
Knock is positioning itself as the notification layer for AI-native products — the thing you reach for when your agent or app needs to send a message. The rapid multi-platform connector release is a deliberate strategy, not a coincidence: each plugin makes Knock a first-class citizen in an AI developer's toolbelt. Expect more data source integrations (after Amplitude) and deeper agentic workflow capabilities.
◆ Prediction
The next move is likely Knock Agents running autonomously: an agent that monitors Amplitude cohorts, triggers workflows, and reports performance back to the team channel — closing the feedback loop without human orchestration.

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.
◆ Current state
Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.
◆ Where it's heading
The Redis L2 integration suggests the Skipper team is addressing the multi-replica cache coherence problem that large deployments encounter. If this pattern continues, distributed-state options—persistent rate limiting, distributed circuit breakers using the same Redis client abstraction—are the natural follow-ons. The high patch cadence signals active production deployment rather than feature-driven development.
◆ Prediction
The Redis client abstraction introduced in v0.27.92 will be extended to other stateful filters, particularly rate limiting, given that distributed rate limiting is the most common request for API gateways running at multi-replica scale.
