The 5x PaaS Pricing Spread: What One API + Worker + Postgres Costs on Railway, Render, Fly.io, Vercel — and a Flat Hetzner Box
A line-by-line recompute of the same API, worker, and Postgres workload across Railway, Render, Fly.io, and Vercel rate cards — plus egress sensitivity to 2 TB, cold-start math, and the flat Hetzner number the whole spread collapses to.
Railway's Per-Second Meter vs Render's Flat Workspace Fee: What a Bursty Side Project Actually Costs in 2026
Railway bills compute by the second under a $5 Hobby floor; Render charges a flat workspace fee plus fixed per-service prices. A worked comparison for a bursty side project and a steady production app — with the crossover math and what a flat Hetzner box removes entirely.
Paying $4,700 for a $1,999 GPU: What the RTX 5090 Street Premium Does to Self-Hosted Inference Math
An RTX 5090 at today's $4,700 street price adds about $75 a month to a self-hosted inference node — while H100 rentals fell roughly 70% from their peak. A worked amortization of both price curves, and where buying still wins.
Upsun Bills You Four Times for One App: What a Typical API + Postgres + Redis Stack Really Costs vs. a €4 Hetzner Box
A line-by-line recompute of a typical API plus Postgres plus Redis stack on Upsun's four-dimension meter versus the same containers on a flat Hetzner CX22, with preview-environment sensitivity math and an honest read on what per-app cloud choice is worth.
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.
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.
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.
