Sessions Live, Sandboxes Die: How Perplexity Cut Agent Sandbox Creation From 185ms to 60ms
Perplexity's SPACE runtime cut agent sandbox creation from 185ms to 60ms median by making the session — not the sandbox — the durable unit. The mechanism, the honest median-vs-tail math, and what it sets as the bar for self-hosted sandboxes.
No Account, 60 Minutes, Zero Trust: The Abuse Controls Behind Anonymous Deploys
Railway's no-account 60-minute deploys show what instant agent-to-preview loops need — and what stops them from becoming free cryptominers. A hostile-user checklist for quotas, network cages, build scanning, and timed teardown on your own Kubernetes fleet.
Four PaaS on One Server: What the 2026 Self-Hosted Boom Gets Right, and What Breaks at Machine Two
Coolify, Dokploy, Dokku, and CapRover top every 2026 self-hosted PaaS roundup. Here is how they compare on multi-machine support, Compose versus Kubernetes portability, and agent-ready MCP surfaces — and where each one beats bex today.
Vercel Pulls Away From Netlify: What a $9.3B vs Shrinking-Rival Split Means for Where Self-Hosting Actually Competes
Vercel tripled revenue to a $340M run-rate and a $9.3B valuation while Netlify shrank and bundled AI add-ons. A worked three-way bill across quiet, typical, and spike months shows where frontend PaaS competition actually happens now.
Vercel Sandbox's Active-CPU Meter vs a €4.99 Hetzner Box: the Breakeven Is 8 Sessions a Day
Vercel Sandbox bills CPU only while code executes — but memory bills for the whole session. A worked per-session comparison showing the memory floor, the ~40% duty-cycle crossover with E2B, and why steady agent-sandbox volume crosses a flat Hetzner box at roughly eight sessions a day.
Durable Objects Just Escaped Cloudflare Twice: Deno's Celld vs Rivet Actors
Deno's celld runs Workers and Durable Objects on your own machines with per-cell SQLite and S3 compare-and-swap; Rivet Actors offers a broader open-source actor platform on Postgres or FoundationDB. A head-to-head on placement, upgrades, write fencing, and what a Kubernetes PaaS must provide to host either beside stateless services.
E2B Serves 88% of the Fortune 100. What Breaks at That Scale Is Idle Billing and Resume Latency
A 30-minute agent session costed three ways shows session-scoped sandbox billing charges mostly for model think time, while suspend/resume latency stacks across dozens of tool calls. What a self-hosted PaaS should design differently.
MCP Went Stateless: Migrating a Deploy-and-Rollback Tool Server Behind an Ordinary Load Balancer
MCP's July 28, 2026 spec removes the handshake and Mcp-Session-Id, making every request self-describing. An 8-step migration plan for a deploy/logs/rollback tool server to replicas behind a plain load balancer — with per-request auth and an audit trail that survives the death of the session.
Railway's Summer of Agents: Sandboxes, Chat-Ops, and the Three Layers of Lock-In
Between June 5 and July 31, 2026, Railway shipped sandboxes, Docker-in-sandbox, preinstalled coding agents, a Slack/Discord platform agent, and ChatGPT/Grok plugins. A close read of what agents-as-tenants plus chat-as-console adds up to, the three layers where the all-in-one-vendor version locks you in, and the self-hosted equivalent on machines you own.
