What is Knock?
Knock pushes an AI agent over its notification stack, from CLI to Slack.
Knock is a developer-first notifications platform, and its recent releases split between hardening the core (MFA, test-runner sandbox mode) and pushing an agent-driven control layer over notification workflows. Teams can now build, trigger, and manage engagement resources from an AI agent — in the dashboard, CLI, or Slack — rather than only through code.
What is Coder?
Coder hardens its core and quietly builds aibridge into a governed AI-agent gateway.
Coder's recent releases split between security maturation and AI infrastructure. A coordinated multi-advisory hardening pass—disclosed via Anthropic's Project Glasswing—tightened OIDC auth, workspace isolation, and agent command handling, with breaking changes, while parallel patches land across four supported release branches (2.29 through 2.34). Underneath, 'aibridge' is emerging as a governed AI gateway.
Knock vs Coder: editorial side-by-side
Knock
6.3INFRA · APIS
Knock pushes an AI agent over its notification stack, from CLI to Slack.
◆ Current state
Knock is a developer-first notifications platform, and its recent releases split between hardening the core (MFA, test-runner sandbox mode) and pushing an agent-driven control layer over notification workflows. Teams can now build, trigger, and manage engagement resources from an AI agent — in the dashboard, CLI, or Slack — rather than only through code.
◆ Where it's heading
The throughline is making notification operations conversational and self-serve: agent skills, dynamic audiences buildable by an agent, a hosted preference center non-engineers can configure, and now the agent inside Slack. Knock is widening who can operate the system beyond developers while keeping its API-first core.
◆ Prediction
Expect the agent surface to keep expanding — more data sources beyond Shopify and deeper agent actions — pulling notification configuration out of code and into conversation and the dashboard.
Coder
7.5INFRA · APIS
Coder hardens its core and quietly builds aibridge into a governed AI-agent gateway.
◆ Current state
Coder's recent releases split between security maturation and AI infrastructure. A coordinated multi-advisory hardening pass—disclosed via Anthropic's Project Glasswing—tightened OIDC auth, workspace isolation, and agent command handling, with breaking changes, while parallel patches land across four supported release branches (2.29 through 2.34). Underneath, 'aibridge' is emerging as a governed AI gateway.
◆ Where it's heading
The throughline is Coder positioning its self-hosted workspaces to host AI coding agents safely: aibridge now tracks new models (Bedrock Opus 4.8, Gemini), enforces auth and request-size limits, and ships under an AI Governance license tier. Security hardening and AI-gateway buildout are advancing in tandem.
◆ Prediction
Expect aibridge to keep absorbing model support and governance controls; the breaking OIDC changes suggest more auth-surface tightening ahead as enterprise deployments consolidate onto the 2.33/2.34 lines.
