Heroku earned its place: git push heroku main defined how deployment should feel, and fifteen years later every platform on this list is still chasing that bar. People leave for three reasons - the free tier is gone (since November 2022), dyno pricing gets expensive at scale, and addons compound the bill: a production Postgres runs $5-$750/month and Redis $15-$750/month, each a separate line item on top of your dynos.
So instead of ranking abstract features, this comparison judges each alternative by how well it replaces the three things you actually use Heroku for: the git push workflow, dynos, and addons. Disclosure: Miget is our product and we list it first - the numbers for every platform are real (as of April 2026; check current pricing pages).
Quick Comparison
| Platform | git push deploys | Dyno equivalent | Addon equivalent | Free tier |
|---|---|---|---|---|
| Miget | Yes (plus Docker, compose, buildpacks) | Unlimited apps in one fixed-price plan | PostgreSQL, MySQL, Valkey, RabbitMQ, Kafka included ($0) | Yes (256 MiB) |
| Render | Yes | Per-service instances from $7/mo | Paid addons (Postgres $6+, Redis $10+) | Yes (sleeps after 15 min) |
| Railway | Yes | Usage-based (per vCPU/GB-second) | Usage-based databases | One-time $5 credit |
| Fly.io | CLI-based (flyctl) | Per-machine from ~$2.02/mo | Self-managed Postgres only | No |
| DigitalOcean App Platform | Yes | Per-container from $5/mo | Separate DB products ($15+/mo) | Static sites only |
| Northflank | Yes | Usage-based, BYOC option | Usage-based databases | Limited free resources |
| Vercel | Yes (Git-native) | Serverless functions (120s cap) | Add-on marketplace (Neon, Upstash) | Yes (non-commercial) |
1. Miget - the addon bill goes to zero
What replaces what: dynos become services inside a fixed compute plan; addons become included managed databases; git push heroku main becomes a Git-connected deploy with buildpack-style zero-config builds (Migetpacks), a Dockerfile, or a docker-compose file.
The structural difference is where the money goes. On Heroku, a web dyno + worker dyno + Postgres + Redis is four line items. On Miget, you buy one compute plan (from $5/month for 512 MiB / 1 vCPU) and run all of it inside: PostgreSQL, MySQL, Valkey (Redis-compatible), RabbitMQ, and Kafka ship included at $0, with HA clusters available when you outgrow a single instance. Every workload runs in its own MicroVM (CloudHypervisor) rather than a shared container, and preview environments - Heroku's paid Review Apps - are included without limit.
- Strengths: flat predictable bill, databases included, buildpack-familiar deploys, MicroVM isolation, IPv6 (Heroku still has none), free tier exists
- Weaknesses: smaller addon marketplace than Heroku's ecosystem, single region per app today (EU + US regions)
- Best for: teams whose Heroku bill is mostly addons and multiple dynos

2. Render - the closest workflow match
What replaces what: dynos become services ($7/month Starter, 512 MB), addons become Render's own managed Postgres ($6+/mo) and Redis ($10+/mo), and git push deploys work the way you expect.
Render is the most Heroku-like migration: native buildpack-style deploys, per-service pricing you already understand, and a real free tier (which sleeps after 15 minutes of inactivity). The caveat is that it inherits Heroku's cost structure - every service and database is a separate line item, so the bill grows the same way, just from a lower base. Teams cost $19/user/month on the Professional plan.
- Strengths: easiest mental model coming from Heroku, solid free tier, good docs
- Weaknesses: per-service costs stack exactly like Heroku's, cron jobs billed separately
- Best for: teams who want Heroku's model at 2015 Heroku prices

3. Railway - usage-based instead of dyno-based
What replaces what: dynos and addons both become metered usage: $20 per vCPU-month and $10 per GB of RAM-month, billed per second, plus $0.05/GB egress.
Railway swaps Heroku's fixed dyno tiers for a meter. That helps bursty workloads and hurts always-on ones - a 24/7 web app plus Postgres lands around $17/month where Heroku's Eco tier would be cheaper but sleeps. The free option is a one-time $5 trial credit; the Hobby plan is $5/month including $5 of usage.
- Strengths: excellent DX, per-second billing granularity, deploys almost anything
- Weaknesses: bill varies with usage, Pro seats cost $20/user, egress fees
- Best for: side projects and bursty workloads where the meter works in your favor
Deep dive: Miget vs Railway.
4. Fly.io - dynos become machines at the edge
What replaces what: dynos become Firecracker microVM machines (from ~$2.02/month for shared-cpu-1x); addons mostly become things you operate yourself - Fly Postgres is explicitly not a managed service.
Fly.io gives you something Heroku never had: 30+ regions with per-second billing. It also gives you something Heroku deliberately hid: operations. You manage your own Postgres, pay $2/month per dedicated IPv4, and pay for bandwidth ($0.02-$0.12/GB). The flyctl CLI replaces git push.
- Strengths: true multi-region, microVM isolation, fine-grained machine sizing
- Weaknesses: self-managed databases, no git push workflow, costs stack per machine
- Best for: latency-sensitive apps that need to run close to users
Deep dive: Miget vs Fly.io.
5. DigitalOcean App Platform - containers plus a separate database bill
What replaces what: dynos become containers ($5/month shared 512 MiB); addons become DigitalOcean's separate managed database products - Postgres from $15/month, Kafka from $149/month, and no RabbitMQ option.
App Platform makes sense if you already live in the DigitalOcean ecosystem. For a Heroku migrant the surprise is the database line: managed Postgres starts at 3x Render's entry price, the free tier covers static sites only, and there are no preview environments.
- Strengths: predictable per-container pricing, mature ecosystem, IPv6
- Weaknesses: database products significantly raise the real monthly total, no Review Apps equivalent
- Best for: teams already running droplets who want apps next to their infrastructure
Deep dive: Miget vs DigitalOcean App Platform.
6. Northflank - pipelines and bring-your-own-cloud
What replaces what: dynos become usage-billed services or workloads in your own AWS/GCP/Azure account (BYOC); addons become usage-based databases.
Northflank leans platform-engineering: strong CI/CD pipelines, jobs, GPU workloads, and the BYOC option that no one else on this list offers. Pricing is usage-based, with the same predictability trade-offs as Railway.
- Strengths: BYOC for cloud credits or compliance, pipelines, GPU support
- Weaknesses: usage-based billing, more moving parts than app-first platforms
- Best for: teams with existing cloud commitments or platform teams outgrowing PaaS
7. Vercel - only if your Heroku app was really a frontend
What replaces what: dynos become serverless functions (120-second cap, no background workers); addons become marketplace integrations like Neon and Upstash, billed by usage; git push becomes best-in-class Git-native deploys.
Vercel is not a general Heroku replacement - no Docker, no long-running processes, no workers. But if what you ran on Heroku was a Next.js or frontend app with an API route or two, Vercel's hobby tier and DX are hard to beat. Pro is $20/user/month.
- Strengths: unmatched frontend DX, global CDN, generous hobby tier
- Weaknesses: serverless limits rule out workers, queues, and long jobs
- Best for: frontend-heavy apps; pair it with a backend platform from this list
Deep dive: Miget vs Vercel.
How to Choose
- Audit your Heroku bill first. If most of it is addons (Postgres, Redis, scheduler), a platform with included databases (Miget) removes those lines entirely; if most of it is dynos, per-service (Render) or usage-based (Railway) pricing may be enough.
- Count your always-on processes. Web + workers + scheduled jobs running 24/7 favors fixed-capacity pricing; occasional burst workloads favor usage-based.
- Check what you cannot give up. Buildpacks: Miget and Render keep the workflow. Multi-region: Fly.io. Review Apps: Miget includes preview environments; on most others they cost extra or do not exist.
Frequently Asked Questions
What is the cheapest Heroku alternative with a free tier?
Miget (256 MiB standing free tier, no credit card) and Render (free tier that sleeps after 15 minutes) both have real free tiers. Railway offers a one-time $5 trial credit. Heroku itself has had no free tier since November 2022.
Which Heroku alternative keeps the buildpack workflow?
Miget (Migetpacks, zero-config builds without a Dockerfile) and Render both support buildpack-style deploys from a Git push. Fly.io requires its flyctl CLI; DigitalOcean and Northflank are container-first.
How do I migrate a Heroku Postgres database without downtime?
Use trigger-based replication - Heroku Postgres does not expose superuser or logical replication, so tools like Bucardo are the standard route. We documented the full procedure: Migrate from Heroku PostgreSQL with zero downtime.
What replaces Heroku Scheduler?
On Miget, scheduled jobs run inside your plan at no extra cost (cron jobs on a PaaS). On Render, cron jobs are billed per run with a $1/month minimum each; on Railway they consume usage credits like any service.
