Railway's $5 vs Fly.io's $2: What the Cheapest Always-On Service Really Costs
Railway advertises $5 with $5 credit, Fly.io a $2 shared-CPU box. Add a 10GB volume and 50GB egress and the cheapest always-on bill tells a different story — with a line-by-line recompute against a €3.79 Hetzner box.
Railway's $5 Hobby vs. a €10 Hetzner Box: What a Solo Dev Actually Pays for an API and a Worker
Railway's $5 Hobby plan covers one tiny service — add a background worker and the same always-on workload costs $40.50 in metered RAM, vCPU, and egress against €10 flat on a Hetzner box, but per-minute billing still wins when average utilization drops below 30%.
Railway vs Render vs Fly.io on July 19, 2026: Same Stack, Three Bills, and Where the Meter Moves First
Techsy re-audited Railway, Render, and Fly.io on July 19, 2026 after all three shuffled plan names — here is a line-by-line recompute of an identical Node.js+Postgres workload, where per-service multiplication and egress tilt the cheapest-to-most-expensive gap, and what the bill collapses to on a flat Hetzner CX22.
AWS European Sovereign Cloud: Why a Separate German Region Still Can't Close the CLOUD Act Gap
AWS went GA in Brandenburg on January 15, 2026 with a separate German entity, 90 services, and €7.8B behind it. Why physically separate still isn't legally sovereign — scored through the EU's SEAL 0–4 framework and the CLOUD Act's corporate-jurisdiction test.
Backblaze B2 Overdrive Promises Unlimited Free Egress: What It Actually Costs vs MinIO and Garage on Your Own Disks
Backblaze B2 Overdrive offers unlimited free egress at $15/TB/month. A worked comparison at 1 TB, 10 TB, and 100 TB shows where it beats standard B2 and R2, and where MinIO or Garage on Hetzner NVMe still wins on control and flat cost.
Your Build Queue Is Idle 80% of the Day: Sizing a Git-Push Pool Without Paying for Peak
A git-push PaaS build queue is bursty by nature — peaks 4–6x the average. A fixed Hetzner pool sized for peak sits idle 78% of the day; sized for average, it queues 10+ minutes at morning burst. A worked comparison of three sizing strategies and the hybrid math that beats both.
Coolify Said No to VCs and Still Won: What a $5 Self-Hosted PaaS Teaches About the Repricing Treadmill
Coolify turned down VC funding and charges a flat $5 per month while Vercel repriced four times since 2024 and Render and Netlify abandoned per-seat billing — proof that a bootstrapped, Apache-2.0 PaaS prices to survive, not to return capital.
Coolify v4.0.0 Goes Stable: What a Two-Year Beta Promoted to Stable Actually Guarantees — and What It Doesn't
Coolify shipped v4.0.0 stable on April 27, 2026 after 468 beta tags, 57,000 stars, and production use by thousands — plus 11 disclosed CVEs. What the stable tag actually guarantees for upgrade and security, what single-host Docker architecture it leaves unchanged, and how to decide whether to pin it today.
Dokploy Switched to Plain Apache 2.0 on January 21, 2026 — Why a Late Cleanup Is Harder to Trust Than Starting Clean
Dokploy replaced its custom Apache 2.0 plus commercial appendix with clean Apache 2.0 core on January 21, 2026. A before-and-after of what changed, what still sits under DSAL, and why a retroactive fix is weaker trust than starting clean.
