Rivet Actors Give an AI Agent State That Survives Between Tool Calls — What a Container-Only PaaS Is Missing
Rivet Actors is an open-source, self-hostable take on Cloudflare Durable Objects, built for AI agent memory and realtime state. Here's what its cold-start and cost numbers actually are, what self-hosting it takes, and whether a container-only PaaS like bex needs to build its own actor primitive.
Sealos and the Rise of Prompt-to-Deploy AI-Native Clouds: What 'Deploy Anything With a Prompt' Gets Right That a Git-Push PaaS Still Doesn't

Vercel's Fluid Compute Pricing Confuses Function Cold Starts With Idle Time: A 2026 Bill Breakdown
Vercel bills cold-start boot time as Active CPU but mid-request I/O wait as Provisioned Memory — two opposite billing treatments for what looks like the same 'waiting.' A worked Next.js bill shows how that split can double a monthly charge with zero traffic change.
Vercel's Turbo Build Machines Are the Default Now — Here's the Real Monthly Bill
Vercel made Turbo build machines the default for Pro projects in February 2026, then cut the per-minute rate 16% in April. Here's the recomputed monthly bill for a real monorepo team, and the build volume where a self-hosted build layer with no per-minute meter actually pays for itself.
