What is Knock?
Knock is building an agent-and-environments layer on top of its notifications infrastructure
Knock is shipping fast on two fronts: an agent surface (trigger Knock from Slack, package reusable agent skills, build audiences via agent) and developer-workflow primitives (reusable input schemas, dynamic audiences that version and promote between environments, new partial input types). The throughline is making notification engineering programmable and agent-operable.
What is Coder?
Coder ships security backports across its 2.29 and 2.31 maintenance lines
Coder's recent releases are maintenance-only: CVE fixes in go-git plus crypto and net dependency upgrades (2.29.16), and a Tailscale-fork fix for a TSMP/ICMP callback leak backported across the 2.29 and 2.31 lines. No new product capability is visible in this window; the work is dependency hygiene and networking stability.
Knock vs Coder: editorial side-by-side
Knock
6.3INFRA · APIS
Knock is building an agent-and-environments layer on top of its notifications infrastructure
◆ Current state
Knock is shipping fast on two fronts: an agent surface (trigger Knock from Slack, package reusable agent skills, build audiences via agent) and developer-workflow primitives (reusable input schemas, dynamic audiences that version and promote between environments, new partial input types). The throughline is making notification engineering programmable and agent-operable.
◆ Where it's heading
Knock is moving from a notifications API toward an agent-operable platform with environment-promotion workflows — audiences, layouts, and inputs all becoming versioned, previewable artifacts drivable from dashboard, CLI, or agent. Expect more agent-triggerable surface area.
◆ Prediction
Likely more agent-driven authoring (additional data sources, agent skills) and continued environment/versioning tooling; the Slack agent and CLI/agent build paths point to deeper automation of notification ops.
Coder
5.0INFRA · APIS
Coder ships security backports across its 2.29 and 2.31 maintenance lines
◆ Current state
Coder's recent releases are maintenance-only: CVE fixes in go-git plus crypto and net dependency upgrades (2.29.16), and a Tailscale-fork fix for a TSMP/ICMP callback leak backported across the 2.29 and 2.31 lines. No new product capability is visible in this window; the work is dependency hygiene and networking stability.
◆ Where it's heading
The pattern is disciplined backporting of security and networking fixes across multiple supported release lines, typical of a self-hosted platform serving enterprise installs that pin versions. Feature direction is not observable from these entries.
◆ Prediction
Expect continued patch releases with security upgrades and networking fixes backported across the supported 2.29 and 2.31 lines.
