Status update: Heroku moved to a sustaining engineering model on February 6, 2026 and no longer offers Enterprise contracts to new customers; self-serve use continues at unchanged prices.

Render, Railway and Fly.io are the three platforms developers most often shortlist when they want Heroku’s “push code, get a running app” workflow without running their own servers. All three deploy from source or a Dockerfile, offer managed Postgres, and bill by usage rather than by server. They differ sharply in pricing model, free options, regions and how much infrastructure they expose.

This comparison is for developers and small teams moving an app off Heroku, or choosing a first platform-as-a-service for a side project or an early-stage product. It is part of our wider guide to hosting for developers, which also covers VPSs, managed WordPress hosts and frontend platforms. One point first: Heroku has not shut down. In February 2026 it moved to what it calls a sustaining engineering model, which is a reason many teams are re-evaluating, but self-serve customers can keep using it at unchanged prices.

This is an editorial research article based on each vendor’s official pricing pages, documentation, changelogs and blog posts, checked on October 17, 2026. We did not deploy test apps or run our own benchmarks, so there are no speed, cold-start or uptime figures here.

Quick verdict

In our assessment, Render is the closest like-for-like Heroku replacement: fixed-price instances, managed Postgres and Key Value, cron jobs, background workers, full-stack preview environments and a free tier for experiments. Railway suits developers who want a fast, project-canvas workflow and pay-for-what-you-consume billing with a low monthly minimum. Fly.io is the most infrastructure-like of the three, built around Machines (lightweight VMs) you can place in 17 regions, with no free tier for new organizations and a Managed Postgres that starts well above the others’ entry databases.

Render — best for teams that want Heroku-style building blocks with predictable per-instance prices.
Railway — best for small projects and prototypes where usage-based billing keeps idle costs low.
Fly.io — best for apps that need to run close to users in several regions, or that want VM-level control.

Heroku’s status in 2026, and why it matters

On February 6, 2026, Heroku’s chief product officer wrote that “Heroku is transitioning to a sustaining engineering model focused on stability, security, reliability, and support”, and that “Enterprise Account contracts will no longer be offered to new customers.” The same post says customers who pay by credit card “can continue to use Heroku with no changes to pricing, billing, service, or day-to-day usage”, and existing Enterprise contracts will be honored and may renew.

Heroku is still shipping: its October 2026 update made Heroku Postgres Advanced available to all teams and set Postgres 18 as the default. We found no announced end-of-life date. Current self-serve prices include Eco dynos at $5 a month for a shared pool of 1,000 dyno hours, Basic at $7, Standard-1X at $25 and Standard-2X at $50, with Heroku Postgres Essential-0 at $5. In our assessment, a move is a planning decision rather than an emergency: the main risks are a slower pace of new features and, for larger companies, the end of new Enterprise contracts.

Pricing models: fixed instances vs metered usage

Render

Render charges a workspace plan plus compute. In April 2026 it replaced per-member pricing with flat workspace plans: Hobby is $0, Pro is $25 a month with unlimited seats, and Scale is $499 a month; remaining legacy workspaces were moved automatically on August 1. Instances have fixed monthly prices, prorated by the second: Starter (0.5 CPU, 512 MB) is $7, Standard (1 CPU, 2 GB) is $25, and Pro (2 CPU, 4 GB) is $85. Bandwidth is 5 GB included on Hobby and 25 GB on Pro, then $0.15 per GB, so a media-heavy app should account for egress.

Railway

Railway’s Hobby plan has a $5 monthly minimum that includes $5 of resource usage; Pro has a $20 minimum with $20 of usage and unlimited workspace seats. Beyond the included amount, Railway charges for resources consumed: $10 per GB of RAM per month and $20 per vCPU per month (both metered per second), $0.15 per GB-month for volumes and $0.05 per GB of egress. Builds are free. Since moving onto its own hardware (“Railway Metal”), Railway lists all four regions as Metal regions. In our assessment, this model is attractive for spiky or mostly idle apps, but it makes the bill less predictable than Render’s fixed instances; Railway’s docs include guidance on usage limits to cap spend.

Fly.io

Fly.io bills Machines per second while they run, with no platform fee. In its lowest-priced US regions, a shared-cpu-1x Machine with 256 MB costs about $2.19 per 30 days, 512 MB about $3.69 and 1 GB about $6.70; prices vary by region. Stopped Machines cost $0.15 per GB-month of root filesystem. A dedicated IPv4 address is $2 a month, and egress is $0.02 per GB in North America and Europe, rising to $0.04 in Asia-Pacific, Oceania and South America and $0.12 in Africa and India. Fly.io’s own docs state that “New organizations don’t have a free tier or a monthly free usage allowance”; organizations on its pre-October-2024 plans keep their old allowances.

Databases and stateful services

For most Heroku migrations, Postgres is the critical piece.

Render Postgres starts free (256 MB RAM, 1 GB storage, expires 30 days after creation, no backups), with paid plans from $6 a month; paid databases get point-in-time recovery (a 3-day window on Hobby workspaces, 7 days on Pro and higher). Render Key Value (Redis-compatible) has a free 25 MB instance and paid plans from $10 a month.
Railway deploys Postgres, MySQL, Redis and MongoDB as services in your project, billed through the same resource meters. Its changelog shows a run of database work in August to October 2026, including high availability for Redis, MySQL and MongoDB and point-in-time recovery for MySQL.
Fly.io Managed Postgres includes high availability, automated backups and connection pooling on every plan, starting at $38 a month (Basic, 1 GB) and $72 (Starter, 2 GB), plus $0.28 per GB-month of storage. Fly’s docs say its older self-run Fly Postgres (unmanaged) “is no longer maintained” and is not supported. Redis is available through Upstash, billed on the Fly invoice.

In our assessment, this is the biggest cost difference for small apps: an always-on small web service plus the lowest-priced paid database comes to roughly $13 a month on Render ($7 + $6) and about $42 on Fly.io ($3.69 + $38), before storage and bandwidth. Railway’s equivalent depends on actual consumption.

Developer workflow: deploys, previews and access

Render is the most Heroku-like: connect a repository, and each push deploys. Background workers, private services, cron jobs and static sites are first-class service types, private networking is automatic, and paid instances support SSH. Full-stack preview environments for pull requests need the Pro workspace plan or higher.

Railway organizes services on a project canvas. It deploys from GitHub repositories, Docker images or the CLI, supports staging and PR environments (“Railway can spin up a temporary environment whenever you open a Pull Request”), and offers a template marketplace. Services can optionally sleep when idle; the docs warn the first request during a cold boot can fail.

Fly.io centres on the flyctl CLI and a fly.toml config file. It has no built-in git-push deploy; Fly’s docs show continuous deployment through a GitHub Actions workflow that runs flyctl deploy. Machines can auto-stop and auto-start on traffic, including scaling to zero, and multi-region placement is a core feature rather than an add-on.

If you only need to host a static or Next.js frontend, a frontend platform may be a better fit; see our Vercel, Netlify and Cloudflare comparison. If you want an all-in-one browser IDE that also deploys, our Replit review covers that route.

Free tiers and their limits

Free options are useful for evaluation but are not equivalent:

Render free web services spin down after 15 minutes without inbound traffic, lose local filesystem changes when they do, share 750 free instance hours per workspace per month, and cannot use disks, SSH or scaling. Free Postgres databases expire after 30 days.
Railway offers a 30-day trial with a one-time $5 credit, then a Free plan with $1 of usage per month, limited to small services (0.5 GB RAM per service, one project, no custom domain).
Fly.io offers only a trial: 2 hours of Machine runtime or 7 days, whichever comes first, with no card required to start.

Prices are in USD and exclude tax. Fly.io prices vary by region, and Railway’s bill depends on what your services actually consume. Check the current figures on each pricing page before you migrate: Render pricing, Railway pricing, Fly.io pricing, Heroku pricing.

Which should you choose?

Choose Render if you are migrating a conventional Heroku app (web + worker + Postgres + Redis + cron) and want fixed, readable prices and PR previews. Watch bandwidth overage at $0.15 per GB.
Choose Railway if you are building prototypes or several small services and prefer paying only for consumed resources, with a low monthly minimum and PR environments. Set usage limits so a runaway service cannot surprise you.
Choose Fly.io if you need multi-region deployment, VM-level control or scale-to-zero Machines, and are comfortable with a CLI-and-config workflow. Budget for Managed Postgres, which starts at $38 a month.
Stay on Heroku if your app is stable, you pay by card, and the sustaining engineering model is acceptable for now. Revisit if you need features Heroku is unlikely to add.

If you would rather run everything yourself on a plain VPS to cut costs, our comparison of unmanaged VPS providers covers the trade-offs.

FAQ

Is Heroku shutting down?

Not according to Heroku. Its February 2026 post describes a transition to sustaining engineering and the end of new Enterprise contracts, while stating that credit-card customers see no change to pricing or service. We found no published end-of-life date as of October 17, 2026.

Which of the three has a real free tier?

Render has an ongoing free tier with spin-down and expiring free databases. Railway has a trial followed by a Free plan with $1 of monthly usage. Fly.io has only a short trial for new organizations.

Can I keep using a Procfile and buildpacks?

All three can build from a Dockerfile, which is the most portable route off Heroku. Render and Railway can also build common languages directly from source. If your app relies on Heroku-specific buildpacks or add-ons, plan time to replace them with each platform’s native services.
