The Free Tier Is Dead (Except Twice): A September 2026 Audit of Where a Side Project Still Lives for $0

The Free Tier Is Dead (Except Twice): A September 2026 Audit of Where a Side Project Still Lives for $0

Only Render and PythonAnywhere still offer free-forever hosting in September 2026 — Railway and Fly.io are trial-credit-only and Heroku has been paid-only since 2022. A verdict table for all six providers plus worked per-project math showing why one €3.99 Hetzner box split across side projects beats every meter.

H100 Rentals Crashed 70%. Should You Still Buy the GPU?

H100 Rentals Crashed 70%. Should You Still Buy the GPU?

H100 rentals fell from $8-10/hour in late 2024 to about $2.50 on specialized clouds. A worked own-vs-rent comparison shows the breakeven moved from 27% to 87% utilization — ownership is now a bet you justify with measurements, not the default.

Heroku Killed 12 TLS Ciphers: The Legacy-Client Audit Your Self-Hosted PaaS Needs Too

Heroku Killed 12 TLS Ciphers: The Legacy-Client Audit Your Self-Hosted PaaS Needs Too

Heroku removed 12 legacy TLS cipher suites and enabled TLS 1.3 with HTTP/2 on August 24, 2026. Here is which clients break, a reproducible openssl/sslyze/testssl.sh audit for your own domains, and the cert-manager plus Gateway API baseline to match it.

Kubernetes 1.37 Kills the Last Idle Pod: Native HPA Scale-to-Zero vs KEDA for Sleeping Apps

Kubernetes 1.37 Kills the Last Idle Pod: Native HPA Scale-to-Zero vs KEDA for Sleeping Apps

Kubernetes 1.37 graduates HPA scale-to-zero to beta and enables it by default: queue workers can shed every replica with minReplicas 0 and no KEDA. HTTP apps still need a buffering layer, and beta isn't ready for a tenant SLA — the head-to-head, the idle-bill math, and the checklist.

One GPU Per Sandbox: What Modal's Whole-Card Bet Costs Against E2B and Daytona's CPU-First Lanes

One GPU Per Sandbox: What Modal's Whole-Card Bet Costs Against E2B and Daytona's CPU-First Lanes

Modal puts whole GPUs inside sandboxes while E2B stays CPU-only and Daytona's GPUs are ephemeral-only. The reason is physical — Firecracker and gVisor cannot pass a GPU through — and the billing consequence is an 8x cost swing on GPU busy fraction alone.

Render Cut Docker Builds From 87s to 32s: Where the Seconds Went and How to Match It on Hardware You Own

Render Cut Docker Builds From 87s to 32s: Where the Seconds Went and How to Match It on Hardware You Own

Render cut median Docker builds from 87 seconds to 32 with upload tuning, faster scheduling, and registry-backed caching. A lever-by-lever teardown of where those seconds lived, and the owned-hardware recipe — warm BuildKit builders, registry cache, cache mounts — that matches it.

Render Taught an AI Agent to Migrate Your Heroku App: What It Gets Right, What Still Needs You, and the Bill at the End

Render Taught an AI Agent to Migrate Your Heroku App: What It Gets Right, What Still Needs You, and the Bill at the End

Render's open-source migration skill lets an AI agent move a Heroku app — dynos, config, Postgres — over MCP in minutes. A line-by-line test of the before/after bill, what the agent nails, where a human is still required, and the five capabilities your own fleet needs before migration becomes a prompt.

Render's 75% Faster Builds, Decoded: What Native Environments Really Measure and the Bar for Self-Hosted Pipelines

Render's 75% Faster Builds, Decoded: What Native Environments Really Measure and the Bar for Self-Hosted Pipelines

Render's native environments claim 75% faster builds than Dockerfiles through intelligent layer caching. Decoding the warm-rebuild arithmetic behind the number, the three Dockerfile mistakes that hand it over, and the benchmark checklist a self-hosted BuildKit pipeline must clear to match it.

France's Railway Runs Kubernetes on Cluster API: What a National Railway's Declarative Rebuild Teaches a Two-Person Fleet Team

France's Railway Runs Kubernetes on Cluster API: What a National Railway's Declarative Rebuild Teaches a Two-Person Fleet Team

SNCF cut cluster provisioning from a month to 30 minutes and now updates every cluster monthly with Cluster API on its own hardware. Three lessons transfer directly to a two-person team on Hetzner — and four pieces of enterprise ceremony to skip.
