Sound Familiar?
Every Heroku frustration, solved.
Heroku problem
"My $7/mo dyno sleeps after 30 min"
Eco dynos spin down constantly. Cold starts kill your API response times and user experience.
Runsite solution
Always-on containers, even on free tier
No sleep. No cold starts. Your app runs 24/7 on dedicated resources in EU data centers.
Heroku problem
"I got a $2,400 bill I didn't expect"
Heroku's autoscaling and add-on pricing is opaque. Surprise invoices are a rite of passage.
Runsite solution
Hard spending limits + alerts
Set a monthly cap. Get Telegram alerts at 80%. We physically cannot charge you more than your limit.
Heroku problem
"Free tier is gone. Hobby is $7/mo per app"
Heroku removed free dynos in 2022. A simple side project now costs $7+/mo minimum.
Runsite solution
Permanent free tier, no credit card
Run side projects, prototypes, and demos forever. Free means free — not "free for 90 days".

// the other side
What about Supabase?
Supabase gives you a great PostgreSQL BaaS. But free projects pause after 7 days, and it's a US company. Runsite gives you always-on EU hosting.
// supabase problems → runsite solutions
Sound Familiar?
Every Supabase frustration, solved.
Supabase problem
"My free project got paused"
Supabase pauses free-tier projects after 7 days of inactivity. Your demo, side project, or staging environment goes offline.
Runsite solution
Always-on free tier
Runsite's free tier doesn't pause. Your app runs 24/7, even if nobody visits for a month.
Supabase problem
"$25/project for Pro is expensive"
Running 3 projects on Supabase Pro costs $75/mo. The jump from free (with pausing) to paid is steep.
Runsite solution
Managed PostgreSQL from €5/mo
Standard PostgreSQL with auto-backups for €5/mo. Add a web service for €5/mo. Total: €10/mo.
Supabase problem
"Edge Functions can't be pinned to EU"
Supabase Edge Functions run on Deno Deploy. You can't control which region processes your requests.
Runsite solution
EU-only compute
Your containers run in our Frankfurt (eu-central) region. Every request is processed in Europe under EU law.

Common Questions
FAQ
Which is better for EU hosting, Heroku or Supabase?
Neither Heroku nor Supabase is EU-native. Both are US-headquartered and route the majority of traffic through US data centers. For genuine EU data residency, an EU-registered platform like Runsite is the safer choice — a Frankfurt (eu-central) region under EU jurisdiction, no transatlantic transfers, no CLOUD Act exposure.
Which has the better free tier, Heroku or Supabase?
Free tiers on both Heroku and Supabase change frequently and often include compute or bandwidth caps that expire after a trial period. If a permanent free tier matters, evaluate the current terms on each provider before committing.
Is Heroku or Supabase GDPR-compliant?
Both can be configured to support GDPR-compliant workloads via Data Processing Agreements (DPAs), but as US entities they remain subject to the CLOUD Act. For workloads where US jurisdiction is a hard blocker, an EU-headquartered provider is required.
What is the cheapest way to deploy a side project — Heroku or Supabase?
Pricing on both Heroku and Supabase can scale unpredictably with traffic or build minutes. Hard spending caps are not available on either platform. Predictable monthly pricing with usage caps is a differentiator to look for elsewhere.
