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 Stytch?
Now inside Twilio, Stytch's independent cadence has slowed to a trickle.
Stytch, the developer identity and auth platform, completed its acquisition by Twilio in late 2025 and has visibly slowed its independent shipping since. The feed is a real changelog but is riddled with duplicate entries; recent activity is limited to an Email Risk fraud-detection beta and housekeeping — the changelog itself is relocating into Stytch's redesigned Docs.
Knock vs Stytch: 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.
Stytch
2.5INFRA · APIS
Now inside Twilio, Stytch's independent cadence has slowed to a trickle.
◆ Current state
Stytch, the developer identity and auth platform, completed its acquisition by Twilio in late 2025 and has visibly slowed its independent shipping since. The feed is a real changelog but is riddled with duplicate entries; recent activity is limited to an Email Risk fraud-detection beta and housekeeping — the changelog itself is relocating into Stytch's redesigned Docs.
◆ Where it's heading
The direction is integration, not expansion: Stytch is folding into Twilio's identity stack and consolidating its own surfaces. Fraud and risk signals (Email Risk, Event Log Streaming) are the main product thread still moving.
◆ Prediction
Expect Stytch's roadmap to increasingly align with Twilio's identity and communications platform; standalone releases will likely stay sparse, weighted toward fraud and migration tooling.
