What is Session?

Session shipped a protocol rewrite and a paid tier, then went publicly broke — the founder is asking users to bail it out.

Session is simultaneously in its most ambitious technical phase and an open funding crisis. Protocol V2 — re-implementing forward secrecy and layering post-quantum cryptography on top of Session's onion-routed transport — has been announced, and the Session Pro paid tier exited beta planning into a December development update. Then in March, cofounder Chris McCabe published a personal appeal saying the project cannot continue developing without user support, and the public feed has been quiet since.

What is Notion?

Notion pivots from app to platform with Workers, External Agents API, and a CLI built for coding agents.

Notion just launched its Developer Platform — Workers (hosted runtime for custom code), an External Agents API to bring Claude, Codex, and Decagon into the canvas, an Agent SDK to embed Notion agents elsewhere, and a CLI aimed at coding agents. In parallel, the Custom Agents product is getting governance scaffolding (admin controls, credit limits, agent directory, Plan Mode for safer multi-step work) and small surface improvements like mobile home and merged cells in tables.

Session vs Notion: editorial side-by-side

Session shipped a protocol rewrite and a paid tier, then went publicly broke — the founder is asking users to bail it out.

◆ Current state

Session is simultaneously in its most ambitious technical phase and an open funding crisis. Protocol V2 — re-implementing forward secrecy and layering post-quantum cryptography on top of Session's onion-routed transport — has been announced, and the Session Pro paid tier exited beta planning into a December development update. Then in March, cofounder Chris McCabe published a personal appeal saying the project cannot continue developing without user support, and the public feed has been quiet since.

◆ Where it's heading

The product roadmap that was meant to fund itself via Session Pro is colliding with the underlying problem the appeal makes plain: the Loki/Oxen-era token economics and donations aren't covering ongoing development. Protocol V2 and Pro are the bets that have to land for Session to remain viable; if Pro doesn't convert a meaningful share of the user base, the next twelve months are about scope reduction, not feature growth. The Feb 1 APT key rotation in January suggests the core infrastructure is still being maintained — for now.

◆ Prediction

Watch for either a hard Session Pro launch and conversion announcement, or a more explicit wind-down / handoff post. A long stretch of silence after a funding appeal usually resolves one way or the other within a quarter; the absence of any new posts since mid-March is itself a signal.

6.3

Notion pivots from app to platform with Workers, External Agents API, and a CLI built for coding agents.

◆ Current state

Notion just launched its Developer Platform — Workers (hosted runtime for custom code), an External Agents API to bring Claude, Codex, and Decagon into the canvas, an Agent SDK to embed Notion agents elsewhere, and a CLI aimed at coding agents. In parallel, the Custom Agents product is getting governance scaffolding (admin controls, credit limits, agent directory, Plan Mode for safer multi-step work) and small surface improvements like mobile home and merged cells in tables.

◆ Where it's heading

The strategic shift is from 'AI inside Notion' to 'Notion as the orchestration layer for any agent.' Workers turn the product into a hosted backend; the External Agents API makes Notion the substrate where third-party agents meet team data. The admin tooling around Custom Agents is the necessary follow-on — once agents proliferate and spend real money, the platform needs spend caps, agent directories, and per-creator throttles, which is exactly what's being shipped.

◆ Prediction

Expect rapid expansion of Worker integrations (more first-party syncs and templates), the External Agents API to graduate from alpha alongside more launch partners, and pricing detail to harden around the August 11 2026 credit-billing flip for Workers.
