Heroku vs Supabase
Heroku vs Supabase compared for European indie developers and small startups. Pricing, EU jurisdiction, GDPR posture, and why Runsite (an EU-registered PaaS in Frankfurt) is worth a look.
Heroku vs Supabase: quick answer
Heroku and Supabase both offer Git-push deploy workflows, but they differ where it counts. Heroku starts around $5/mo. Heroku and Supabase are both US-headquartered, so neither escapes US jurisdiction or the CLOUD Act, and neither runs EU-native infrastructure or offers hard spending caps. For European teams that need GDPR-compliant hosting in Frankfurt with predictable EUR billing and a permanent free tier, Runsite is the EU-native alternative to both.

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".

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.

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.

// pricing, side by side
Heroku vs Supabase: what each actually costs
No free tier at all: Heroku discontinued free dynos, Postgres and Redis in November 2022.
Heroku still has the cleanest developer experience, but its pricing punishes hobbyists and small teams: no free tier, expensive production databases, and add-ons that quietly multiply the bill.
Pricing verified June 2026. Check the official pricing page of each provider for current rates.

How Heroku and Supabase each compare to Runsite
Heroku vs Runsite
Heroku is still the best-known name in deployment and one of the worst values for an indie developer. Both things are true at once. It pioneered the PaaS category and defined what developer-friendly deployment looks like: the git-push workflow, the add-on marketplace, and the buildpack system influenced every platform that followed, and the name survived even Salesforce's acquisition.
The problem is the trajectory. Free dynos were eliminated in 2022, Eco dynos sleep after 30 minutes of inactivity, and pricing has steadily increased, so a basic app with a database now costs $16+/mo minimum. Heroku is also a US company with EU data residency available only on enterprise plans. Runsite keeps always-on containers even on its free tier, runs EU-only infrastructure in Frankfurt (eu-central), and enforces hard spending limits with Telegram alerts.
If you learned to deploy on Heroku and want the same git-push simplicity with lower costs, EU data residency, and a free tier that actually persists, Runsite preserves that workflow while fixing the pain points Heroku introduced over the past few years.
Supabase vs Runsite
The dealbreaker for a lot of European developers is one line in the free-tier terms: Supabase pauses free-tier projects after 7 days of inactivity, so your staging environment or demo app goes offline without warning. That weighs more than any feature list.
For context, the rest is strong. Supabase has built an impressive open-source platform around PostgreSQL, with auto-generated REST and GraphQL APIs, built-in auth via GoTrue, real-time subscriptions, and edge functions, plus a community Firebase cannot match. But there is a second catch: it is a San Francisco-based US company, so CLOUD Act jurisdiction applies to your data regardless of region selection. Paid plans start at $25/project/mo, making multi-project setups expensive.
Runsite's free tier never pauses, managed PostgreSQL starts at €5/mo, and the platform operates as an EU entity with all data in European data centers. Developers who want PostgreSQL hosting with EU data sovereignty, always-on availability even on the free tier, and lower per-project costs will find Runsite addresses the limitations European Supabase users hit most.

Common Questions
FAQ
Which is better for EU hosting, Heroku or Supabase?
Neither Heroku nor Supabase is EU-native. Both are US-based (Heroku: US-headquartered (Salesforce); Supabase: US-headquartered (open source)) and route most traffic through US regions, with EU availability that is usually limited or gated behind higher tiers. Even when you can select a European region, the parent company stays subject to the US CLOUD Act, which can compel disclosure of EU customer data. For genuine EU data residency, an EU-registered platform is the safer choice: Runsite runs exclusively in Frankfurt (eu-central) under EU jurisdiction, with no transatlantic transfers and no CLOUD Act exposure — the kind of guarantee neither US provider can make.
Which has the better free tier, Heroku or Supabase?
Free tiers on both Heroku and Supabase change frequently and tend to share the same catch: compute that sleeps after inactivity, bandwidth or build-minute caps, or trial credits that expire after a fixed window. They are fine for quick experiments but rarely sustainable for an always-on hobby project. If a permanent free tier matters, read the current terms carefully. Limits are often buried in the pricing footnotes. Runsite takes the opposite approach: a free tier with no credit card and no expiry, designed to keep small projects online indefinitely rather than nudging you onto a paid plan.
Is Heroku or Supabase GDPR-compliant?
Both Heroku and Supabase can be configured to support GDPR-compliant workloads through a signed Data Processing Agreement (DPA) and EU region selection where available. However, as US-incorporated entities they remain subject to the US CLOUD Act regardless of where the data physically sits, which is a documented sticking point for European compliance and DPO review. For workloads where US jurisdiction is a hard blocker (public-sector, healthcare, or privacy-sensitive consumer apps), an EU-headquartered provider removes the ambiguity entirely. Runsite is EU-registered with data kept inside the EU, so GDPR posture is the default rather than a configuration exercise.
What is the cheapest way to deploy a side project, Heroku or Supabase?
For a single small service, both Heroku and Supabase can look inexpensive on paper. The headline price rarely matches the real bill. Per-service billing, metered bandwidth, build minutes, and add-ons for databases or key-value stores stack up quickly, and neither platform offers a hard spending cap to stop a surprise invoice. The cheapest predictable option is one with fixed monthly pricing and an enforced ceiling. Runsite bills in EUR from €5/month with hard spending caps and Telegram alerts, plus a permanent free tier, so a side project stays cheap by design, not by careful monitoring.
