What is Inngest?
Durable execution platform pushes into low-latency runtime and AI-agent developer workflows.
Inngest is a durable workflow execution platform built around a TypeScript SDK. The last six months ran two strategic bets in parallel: chasing AI-workflow latency (Checkpointing cut workflow duration by 50%, then Durable Endpoints extended durability into plain API handlers) and making the platform a first-class target for AI coding agents (Dev Server MCP, Agent Skills, markdown docs URLs). TypeScript SDK v4 GA in March consolidated this as the default experience.
What is CircleCI?
CircleCI ships an MCP server and auto-rollback deployments, moving well past pure CI.
CircleCI has shipped three directional moves in two weeks: a hosted MCP server that gives AI assistants 24 tools to read and act on pipelines, Smart Deployments with automatic monitoring-triggered rollback, and the Machine Runner Orchestrator reaching GA with multi-resource-class autoscaling. The product is no longer just a CI runner — it now spans self-hosted infrastructure management and post-deploy validation. Cursor Origin integration in beta extends that reach into AI-native development environments.

Inngest
0.0INFRA · APIS
Durable execution platform pushes into low-latency runtime and AI-agent developer workflows.
◆ Current state
Inngest is a durable workflow execution platform built around a TypeScript SDK. The last six months ran two strategic bets in parallel: chasing AI-workflow latency (Checkpointing cut workflow duration by 50%, then Durable Endpoints extended durability into plain API handlers) and making the platform a first-class target for AI coding agents (Dev Server MCP, Agent Skills, markdown docs URLs). TypeScript SDK v4 GA in March consolidated this as the default experience.
◆ Where it's heading
Inngest is broadening from 'workflow engine' to 'durability primitive any TypeScript handler can wrap with step.run().' Realtime moving into the core SDK and Durable Endpoints both shrink the surface gap between 'calling Inngest' and 'writing a normal handler.' The AI-agent investments suggest they expect new project onboarding to happen via a coding agent installing skills, not a developer reading docs.
◆ Prediction
Expect Durable Endpoints to graduate from public beta (currently Next.js and Bun only), realtime APIs to expand to more frontend integrations, and the Agent Skills set to grow into the longer tail of testing, deployment, and debugging workflows.
CircleCI
8.8INFRA · APIS
CircleCI ships an MCP server and auto-rollback deployments, moving well past pure CI.
◆ Current state
CircleCI has shipped three directional moves in two weeks: a hosted MCP server that gives AI assistants 24 tools to read and act on pipelines, Smart Deployments with automatic monitoring-triggered rollback, and the Machine Runner Orchestrator reaching GA with multi-resource-class autoscaling. The product is no longer just a CI runner — it now spans self-hosted infrastructure management and post-deploy validation. Cursor Origin integration in beta extends that reach into AI-native development environments.
◆ Where it's heading
CircleCI is positioning itself as a control plane for the full software delivery lifecycle, not just CI. The MCP server is the clearest signal: the bet is that AI agents will manage CI pipelines, not just execute them. Smart Deployments targets the CD-to-production gap historically owned by separate tooling like Argo and Spinnaker. If both bets compound, CircleCI competes in a substantially broader market than it has historically occupied.
◆ Prediction
The next likely move is expanding MCP tool coverage — particularly config generation and test intelligence — and graduating Cursor Origin from beta to GA. Smart Deployments will likely add more monitoring integrations beyond Datadog and Prometheus, with Honeycomb and Grafana Cloud as obvious candidates.
