HostingGuru
The HostingGuru blog.
Practical writing on deploying apps, comparing PaaS options, and hosting things that actually stay online. Written by the team building HostingGuru — a senior backend engineer running a managed PaaS for developers, freelancers, and non-technical founders.
Your crontab is silently failing. The 5 silent killers of VPS-based cron jobs (and the modern setup that fixes them in an afternoon).
Cron itself isn't broken — it's been working since 1975. The operational layer around it on a $5 droplet is. Five specific failure modes: wrong crontab, empty environment, output to /dev/null, single-point-of-failure host, overlapping runs. Plus the three-piece modern setup (platform-managed scheduler, per-run logs, exit-code alerts) that retires them all.
Your Stripe webhook is going to silently drop a paid customer. Here are the 4 patterns that catch it before they chargeback.
Webhooks fail. Network blips, deploy gaps, duplicate deliveries, 3-day retry windows that quietly expire. Four production patterns — verify-and-ack-fast, idempotency on the event ID, a worker with dead-letter and backoff, and the daily reconciliation cron — with Node.js and Postgres code you can drop in tonight.
Your indie SaaS has zero working Postgres backups. Here's the 20-minute fix (and the drill you need to run before you sleep tonight).
A no-AWS, no-S3-quagmire backup strategy for solo founders running Postgres. The 4-line cron with pg_dump and rclone, the off-vendor bucket on Backblaze B2 or Cloudflare R2, a 30-day lifecycle rule, the restore drill, and the 3 mistakes I see every week on review calls.
The Claude Code → production checklist: 15 things that aren't obvious until they bite you.
You shipped your MVP with Claude Code. Now here's the production-readiness checklist nobody warned you about — committed .env files, missing rate limits, test keys in prod, source maps, CORS, and 10 other quiet killers. Each item with a 10-minute fix.
I migrated 12 client projects off Heroku. Here's the playbook (and the 7 things that bit me every time).
After 12 migrations to Render, Railway, Fly.io, HostingGuru, and back-to-VPS, the order of operations matters more than the destination. The 8-step playbook plus the 7 specific things that broke in production every time — heroku_ext schema, sslmode, DYNO env var, scheduler timezone, and more.
How I built a Discord 'ship-tracker' bot in a weekend (and the 3-process architecture that keeps it alive 24/7).
A real build log: free hosting tiers killed v1 in 15 minutes because Discord bots maintain a WebSocket gateway, not HTTP traffic. Here's the web service + worker + scheduled-script architecture that fixed it — with discord.js code you can copy.
Telegram alerts for any production app — a 5-minute setup (no SaaS, no signup, just curl).
Email gets buried, Slack gets muted. Telegram pings you on the lock screen. Wire production alerts to a Telegram bot in 5 minutes, on any stack, for $0. Includes Node.js, Python, and bash examples plus the rate-limiting trick that prevents alert spam.
Your AI app is silently burning $2,000/month and you don't know it. Here are the 5 patterns that bite founders.
Five real production patterns that quietly drain AI budgets while everything looks fine in your dashboard — retry loops, self-triggering agents, fingerprint aggregation blind spots, context bloat, abandoned crons. Plus what to do tonight.
I built my MVP with Claude Code. Now I need to deploy it. Here's what nobody tells you.
If you built your first SaaS with Claude Code, Cursor, or Lovable, deploying it to production is the part nobody warned you about. Here's the honest map of what you actually need — and why most platforms aren't built for you.
Heroku just went into "sustaining engineering mode." Here are 5 alternatives whose free tier actually doesn't sleep.
Heroku stopped shipping new features in February 2026. If you're shopping for alternatives, the one thing most comparison posts miss is whether the free tier actually stays online — or if it sleeps after 15 minutes of inactivity. Five PaaS options evaluated on exactly that.
What you will find on the HostingGuru blog
The HostingGuru blog is a long-form engineering publication written by the team operating HostingGuru, a managed Platform-as-a-Service used by developers, freelancers, and small SaaS teams to deploy applications directly from GitHub. Every post is grounded in real production work — client migrations, post-mortems, support tickets, or things we built into the platform itself.
We publish roughly one in-depth article every 1–2 weeks. Most posts run between 1,500 and 3,500 words and are aimed at engineers who already ship to production but want a sharper opinion on a specific problem: Heroku migration ordering, Stripe webhook idempotency, Discord bot architecture, AI cost observability, Postgres backup hygiene.
Topics we cover in depth
Heroku migration and PaaS comparison
Heroku entered sustaining-engineering mode in February 2026, which means no new features and no roadmap. Our migration coverage is built on 12 real client migrations off Heroku to HostingGuru, Render, Railway, and Fly.io. We document the actual order of operations, the seven things that bite every migration (heroku_ext schema, hard-coded DYNO env vars, sslmode=require, pg_stat_statements), and the realistic time budget for small Node, Python, and Rails apps.

Stripe webhooks, Postgres, and production reliability
Most indie SaaS outages we see during reviews follow the same handful of failure modes: a Stripe webhook silently dropping a paid customer, a Postgres database with backups that have never been restored, an alert pipeline that emails a buried inbox at 3am. Our reliability coverage gives drop-in patterns, not vague principles.

- A 20-minute Postgres backup strategy for solo founders
- 5-minute Telegram alerts for any production app
- 5 silent killers of VPS-based cron jobs (and the modern fix)
AI-built MVPs (Claude Code, Cursor, Lovable)
AI coding agents produce working code, but they do not produce production-ready services. Rate limits, env-var hygiene, error monitoring, instant rollback, billing-event idempotency — these are out of scope for the agent and become the founder's problem at deploy time. We track this gap and publish concrete checklists.

- 5 patterns that quietly drain AI budgets

Discord, Telegram, and chat-bot architecture
Chat bots have a unique runtime shape: a long-lived gateway WebSocket, scheduled work, and occasional admin HTTP traffic. Free-tier PaaS often kill these in 15 minutes because the platform's idle detector watches HTTP, not gateway events. Our coverage documents architectures that survive real traffic.
- Discord bot 3-process architecture that stays up
- Deploy a background worker (the right shape for bots)
- On-demand scripts for scheduled digests
How to read the HostingGuru blog
Who is the HostingGuru blog written for?
Senior backend engineers, indie SaaS founders, freelancers building client work, and small agency teams. We assume you can read code in at least one of Node.js, Python, or Ruby, and that you have shipped to production at least once before. We avoid intro material that is well covered elsewhere.
How often is new content published?
New deep-dive articles are published every 1–2 weeks. Each post is timestamped at the top and silently updated when the underlying platforms (Stripe, Heroku, Discord, Claude Code, Postgres major versions) change behaviour that affects the recommendations.
Can I republish or quote HostingGuru blog posts?
Short quotes with attribution and a link back are welcome. For full republication on Hashnode, Dev.to, or Medium, write to [email protected] first — we maintain canonical-URL discipline so cross-posted articles don't compete with the original in search.
Who writes for the HostingGuru blog?
Posts are written by HostingGuru engineers, led by founder Chalom Ellezam (senior backend engineer, 10+ years), with occasional contributions from senior engineers in the community. Every post is reviewed for accuracy before publishing — no AI-generated filler, no thin listicles.
Where to start
If you are migrating off Heroku, start with the 8-step playbook. If you shipped an MVP with Claude Code, start with the production checklist. If you have a Stripe-billed product without idempotent webhooks, fix that tonight with the 4-pattern guide. If you want to subscribe to new posts, follow us on Discord.
