A $10 Hetzner VPS Hosts a Dozen Small Projects Where Managed PaaS Costs $50-100: Auditing the Math

Twelve projects for ten dollars a month, or the same twelve for fifty to a hundred on a managed platform. That is the starkest cost claim in SoloDevStack's September 2026 "Coolify vs Caprover for Solo Developers" comparison: "A $10/mo Hetzner VPS can host a dozen small projects with Coolify, where the same workloads on a managed PaaS would cost $50 to $100/mo." A 5-10x gap is the kind of number that ends debates — which is exactly why it deserves an audit before you act on it.

This post prices both sides receipt by receipt, names the three assumptions quietly doing the heavy lifting, and finds the point where the gap dies. Short version first: the cash gap is real, roughly $11-14 out of pocket versus $50-104 managed for the basket defined below. But it survives only if your ops time is worth near zero and you accept single-box risk. The moment either assumption breaks, the 5-10x collapses to 2x or vanishes.

The $10 claim, quoted precisely​

Before auditing a number, fix what it prices. SoloDevStack's comparison (September 13, 2026) pits Coolify v4.1.1 — around 56,100 GitHub stars, free self-hosted under Apache 2.0, with an optional $5/month Cloud tier covering two servers — against CapRover v1.14.2, the older stability pick running since October 2017 with around 15,000 stars, free and self-hosted only. The $10 figure is the Hetzner side of that comparison: one VPS, Coolify installed with the one-line script, a dozen small projects deployed through its dashboard.

For this audit, "a dozen small projects" means a concrete basket: twelve always-on web services (side projects, client prototypes, bots, internal tools), two or three backed by Postgres, one sharing a Redis, TLS via free Let's Encrypt certificates. That is the workload both sides below are priced against — no sleep-to-zero tricks, no shared-everything monolith, just the ordinary sprawl of a busy solo developer.

The verdict up front (receipts below)​

Priced honestly, the two sides land here for that basket:

Three conclusions follow, and the rest of this post proves each one. First, the $50-100 range is fair-to-conservative against per-service pricing like Render's, but high against usage-based platforms like Railway for idle-light workloads. Second, the undisputed cash savings — about $40-90 a month — buy roughly one to two hours of a professional's ops time before the gap inverts. Third, the gap assumes one machine forever; the second box is where the math starts dying. If you only remember one sentence: the $10 box wins on cash and loses on everything cash doesn't measure.

Pricing the managed side: $50-100, receipt by receipt​

Start with Render, the platform SoloDevStack's range fits best. Render's always-on Starter tier is $7 per month per service with 512 MB of RAM — the free tier sleeps after 15 minutes idle, so it doesn't count for anything users touch. Twelve always-on services is $84 before data. Add Postgres: the free database expires after 30 days, so the paid entry is roughly $7 for 256 MB or about $20 once you want 1 GB. Even sharing one Postgres across all twelve projects, the managed total lands at $91-104 a month.

Against Render, SoloDevStack's "$50 to $100" isn't hype; the top of the range is the honest number and $50 assumes fewer services or some sleeping.

Railway tells a less flattering story for the claim. The Hobby plan is $5 a month including $5 of usage credit, and every service — app, Postgres, Redis, worker — meters CPU and RAM independently, 24/7. A typical Next.js-plus-Postgres-plus-Redis stack runs about $10-15 a month on Railway; scale that pattern down to twelve small, mostly-idle services sharing databases and you land around $30-60. That sits inside SoloDevStack's range but toward the bottom — and for truly tiny workloads it can dip under $50. Fly.io's pay-per-VM-second model behaves similarly at roughly $3-8 per small service.

So the $50-100 claim is representative, not cherry-picked — but only for per-service platforms. A reader comparing against Railway or Fly for lightweight side projects should pencil in $30-60, which cuts the fabled gap roughly in half before the audit even reaches the hidden costs.

Pricing the self-hosted side: $10 plus the fine print​

Now the other column. A ~$10/month Hetzner box after the April 2026 price increase buys roughly 4 vCPU and 8 GB of RAM class with 160 GB of disk and 20 TB of included traffic — genuinely enough for twelve small containers plus databases, with headroom. (The smaller CX22 at around €4.50 is the famous $5 box; $10 doubles it.) Coolify and CapRover are both $0 self-hosted, so software adds nothing to the bill.

The fine print is backups, and it is small but not zero. Coolify treats databases as first-class resources with scheduled S3-compatible backups; CapRover treats them as catalog apps and leaves backups to your own cron jobs. Either way you pay for where the bytes land: Hetzner snapshots run about 20 percent of the server price (~$2), or a few dollars of S3-compatible object storage for database dumps. Call it $1-4 depending on retention. Total out of pocket: ~$11-14 a month. Domains and DNS cost the same on both sides, so they cancel out of the comparison.

This is also where the Coolify-versus-CapRover choice has cost consequences the headline hides. Coolify's built-in backup schedules and database lifecycle management are labor you don't perform; CapRover's DIY backup story converts every one of those features into your evening. Both are free software. Only one of them is free operations.

The three assumptions doing the heavy lifting​

Assumption one: your ops hours are worth zero. The cash gap is $40-90 a month. Price your time and watch what happens:

One failed Coolify upgrade, one Let's Encrypt renewal mystery, one 2 a.m. "why is the box at 100% disk" — a single incident quarter can consume a year of savings at professional rates. Hobbyists rationally value the time at zero because tinkering is the hobby. Anyone billing hours should do the breakeven honestly: if the box costs you ninety minutes a month, Render was cheaper.

Assumption two: single-box blast radius is acceptable. Twelve projects on one VPS means one kernel, one disk, one correlated failure domain. When — not if — the box dies, the restore drill is yours to run: Coolify's instance recovery needs the database backup plus the APP_KEY plus the generated SSH keys, with app configs living under /data/coolify; CapRover's is whatever you scripted. Nobody pages you at 3 a.m. on Render because there is no box to die — that sentence is the entire $80 difference. The $10 math also assumes you have tested the restore, which almost nobody has until the day they need it.

Assumption three: stateful services are self-managed. Postgres on your VPS is Postgres you upgrade, vacuum, back up, and restore. Managed Postgres at $7-20 a month bundles minor-version upgrades, point-in-time recovery, and failover you never think about. For two or three small databases this is maybe thirty minutes a month of calm maintenance — until a major-version upgrade or a corruption scare turns it into a weekend. The audit-fair way to say it: self-managed state is cheap exactly until the month it isn't, and that month isn't in the $10 figure.

Where the 5-10x gap dies: the second machine​

Every assumption above holds on machine one. Machine two is the breakpoint, and it arrives through predictable triggers: one project's traffic starts starving the other eleven (noisy-neighbor separation), a client asks what happens if the host dies (HA), or you want staging to stop sharing a kernel with production. Each trigger adds roughly another $10 box — and the gap math degrades fast:

Note what the second machine doesn't fix: your database still lives on one disk unless you build replication yourself, and CapRover offers no managed control plane at any price — its Swarm clustering is free but entirely yours to operate. The managed-platform bill, meanwhile, barely moves when you add resilience, because redundancy is already in the $7-per-service price. The honest decision rule: the $10 box wins while one machine suffices; budget the second machine the month a project matters, and re-run the breakeven then.

Who the $10 box is actually for​

The audit lands the claim intact but bounded. SoloDevStack's 5-10x gap is real cash for a defined basket against per-service managed pricing — not marketing fiction. It just prices the hardware while assuming away the labor, the risk, and the growth.

The decision maps cleanly onto three profiles. Hobbyists and learners should take the $10 box and never look back: the ops time is recreation, the blast radius hits side projects, and twelve projects for the price of two coffees is genuinely unbeatable. Solo founders with revenue should take the box too — but on day one, price ninety minutes a month of ops, automate backups to off-box storage, and actually run a restore drill; the gap pays for that discipline with room to spare. Small teams and anyone with a client SLA should treat the $10 figure as the cost of staging, not production: shared on-call for one VPS, no redundancy, and restore procedures living in one person's head is how outages become incidents.

However you choose, choose it with both columns summed. The most expensive infrastructure decision isn't picking the $10 box or the $100 platform — it's picking either one while believing the other's costs don't exist.
