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.
Same Cluster API, Different Bill: What Vultr's CAPI Support Proves About the Standard (and the Metal)
Vultr has spoken Cluster API since October 2024 — so why doesn't the standard settle where your fleet lives? Same CAPI shapes, different bills: a sourced cost comparison, what portability really covers, and why owned metal still wins.
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.
Fly.io Started Billing What Used to Be Free: The Two 2026 Line Items, Priced
Fly.io began metering volume snapshots in January 2026 and cross-region private traffic in February 2026. A line-by-line recompute shows the two new charges adding roughly $9 to a $33 three-region bill, against $15 flat on owned Hetzner hardware.
Kratix Promises Are Platform-as-Product: What Workflow Retries and Compound Promises Mean for a Fleet That Hand-Rolls Operators
A July 2026 hands-on replaced an entire ops ticket queue with three Kratix promises serving in 30 seconds. How the promise model works, what SKE v0.45.0's workflow retries changed, what compound promises buy a Cluster API fleet's preview environments and quotas, and the threshold where promises beat shell scripts.
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.
50 Pull Requests, 50 Live Environments: What Preview-at-Scale Really Costs on Railway vs Owned Hardware
Fifty concurrent pull-request previews cost about $585 a month on Railway's per-minute meter versus $30-95 on a Hetzner-backed Cluster-API fleet. A worked comparison of per-namespace accounting, image-cache sharing, Gateway API route churn, and the probe design that decides whether idle previews actually sleep.
