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 Retool?

Retool is retiring standalone Assist while folding the same capability into the app builder.

Releases arrive several times a week and split into two lines. One extends the app-building agent — plan mode, managed agent context, multiple threads per branch — and the other builds out governance: access policies on PostgreSQL resources down to row level, BYOK AI token management, an admin onboarding hub. Against that, Assist is being removed outright on September 30, 2026.

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.

Retool is retiring standalone Assist while folding the same capability into the app builder.

◆ Current state

Releases arrive several times a week and split into two lines. One extends the app-building agent — plan mode, managed agent context, multiple threads per branch — and the other builds out governance: access policies on PostgreSQL resources down to row level, BYOK AI token management, an admin onboarding hub. Against that, Assist is being removed outright on September 30, 2026.

◆ Where it's heading

The agent is being consolidated into the app builder rather than offered as a separate assistant, and Assist's removal is the clearest statement of that. Alongside it, the controls an administrator needs before letting an agent touch production data are arriving in the same cadence — resource-level policies, token management, permission migrations. Retool is treating agent capability and agent governance as one shipping problem.

◆ Prediction

Access policies should extend past PostgreSQL to other resource types as they exit beta, and the app-building agent will likely gain review or approval steps of its own.
