Notion is rolling out a secure Workers sandbox to run custom code and synchronize data from external systems like Salesforce or Zendesk, enabling agent tools and webhook-triggered actions, with a free preview lasting through August 11, 2026 before pricing at $10 per 1,000 monthly credits and a public beta for database sync.

At a May product event, Notion unveiled a Developer Platform that positions Notion as an orchestration layer where AI agents operate as native participants inside workspaces alongside human teammates.

The External Agents API lets teams connect named partner and internally built agents, broadening access to data and tools beyond engineers, currently in private beta with a waitlist for access.

Notion warns of potential prompt-injection risks with AI agent workflows and notes that defenses and admin controls have already been enhanced, a priority as external data access and code execution expand.

The May 13 release builds on the February 2026 Custom Agents launch, which saw over a million Custom Agents created in two months, by enabling external data access, external code execution, and cross-Notion agent interactions.

Notion frames its platform as infrastructure that lets users pick the best agent for each task and centralizes activity in one workspace, distinguishing itself from rivals that push their own stacks.

Core platform components include Workers (hosted runtime for custom code), a live data sync layer from external systems, and the External Agents API enabling agents like Claude Code, Cursor, Codex, and Decagon to participate in Notion workspaces.

Notion is financially strong ahead of any IPO, with about $11 billion valuation from a January 2026 secondary tender, over $600 million ARR, and more than half of revenue coming from AI-enabled customers, framing the Developer Platform as a strategic founder-led move.

FAQ confirms compatible agents (Claude Code, Cursor, Codex, Decagon, and internally built agents), private beta status, the Workers free preview through mid-August 2026, and post-preview pricing details for credits.
