Very cool to see Pi build a durable agent harness too. I've been building in this space for quite some time myself [0][1] and it is a super interesting place of innovation. Less hype-y that on-your-machine coding agents, but all major players are building products in this space: LangChain Deep Agents, Vercel Eve, OpenAI Agents API, Anthropic Managed Agents, etc.
The main reasons are:
1) they are "durable", i.e. easier to make long-running in an unattended way, and easier to implement recovery, monitoring, etc
2) separating the harness from the compute brings safety and scaling benefits
Pi is anyway a better option than all the others, because of it's focus on agnosticism. Vercel's SDK will work slightly better with it's AI gateway, OpenAi's Agent will work better with codex models, and so on.
Pi-durable makes pi a good acquisition target for Cloudflare - nothing like durable objects (with containers no less) really exists in other clouds. Wonder what the_mitsuhiko thinks about this.
From what I know (someone correct me if I'm wrong) Pi/Earendil is VC-backed so it's just a matter of time really. I don't see any other end game for them as a company other than being acqui-hired. In this regard I have more faith in something like Zed (the code editor, VC-backed too) to retain their "independence".
Pi is alright but it's only virtue so far is being the Neovim of harnesses, minimal yet (incredibly) extensible. That being said it's still early days and unclear how the whole landscape regarding agentic stuff will play out at various different levels. For example I prefer stuff like Claude Code and Pi but I've seen a friend use Kiro at work with some crazy workflows all basically structured around Markdown files, spec writing, ingesting tickets from Jira and then validating/testing the code written automagically.

> acquisition target for Cloudflare
Once it gets acquired, it won't be any better than all the others.
