Heroku Alternatives: 6 Platforms to Host Your App in 2026

The best Heroku alternatives compared: Render, Railway, Fly.io, DigitalOcean App Platform, Vercel and Mythex. Free tiers, pricing and who each one suits.

The best Heroku alternatives are Render for the closest like-for-like switch, Railway for simple usage-based pricing, Fly.io for running apps close to users in many regions, DigitalOcean App Platform for low fixed prices, Vercel if your app is really a frontend with some serverless functions, and Mythex if you want an AI to build and host the app for you. Heroku itself is still a mature platform, now with a newer Kubernetes-based generation and built-in AI model access. The usual reasons to move are price and the lack of a free tier.

What Heroku offers today

Heroku is a platform as a service (PaaS): you push code, and it builds and runs it on "dynos", its name for app containers.

As of September 2026, Heroku's pricing page lists:

• Dynos: Eco $5/month (sleeps after 30 minutes of inactivity), Basic $7/month (always on), Standard-1X $25/month, Standard-2X $50/month, Performance-M $250/month.
• Heroku Postgres: Essential-0 $5/month (1 GB), Essential-1 $9/month (10 GB), Essential-2 $20/month (32 GB), with larger plans above.
• Fir: a newer Kubernetes-based generation that requires a Private Space, with dynos from $25/month.
• Managed Inference and Agents: access to large language models, priced per million tokens.

There's no free tier on the pricing page.

Why people look for Heroku alternatives

1. No free tier. Hobby projects and prototypes now cost money from the first day.
2. Cost as you grow. A web dyno, a worker and a production-grade database add up.
3. Regions and latency. Some apps need to run in many regions close to users.
4. Modern pricing models. Some teams prefer paying per second of use instead of per dyno per month.
5. They don't need a full PaaS. A frontend with a few API routes may fit a frontend host better.

How we compared

We compared the publicly stated features, limits and prices on each vendor's own website, pricing page and documentation as of September 2026. We did not do hands-on testing, deploy benchmarks or uptime measurements, and we left out anything we couldn't confirm on the vendors' pages. Prices are in US dollars. Mythex facts come from our product documentation.

Render: the closest like-for-like switch

Render hosts web services, private services, background workers, cron jobs, and managed Postgres and Redis-compatible databases. If you think in Heroku terms, Render maps across naturally.

• Pricing (as of September 2026): workspace plans are Hobby ($0/month plus compute), Pro ($25/month plus compute), Scale ($499/month plus compute) and custom Enterprise. Web service compute ranges from a free instance to Starter at $7/month (512 MB RAM) and Standard at $25/month (2 GB RAM). Managed Postgres starts free, with paid instances from $6/month.
• Free tier limits: Render spins down a free web service after 15 minutes without traffic, and free Postgres databases expire 30 days after creation.
• Strengths: familiar PaaS model, managed databases, cron jobs, private networking, previews.
• Limits: the free tier is for trying things out, not for production.
• Pick it if you want the least change from Heroku.

Railway: pay for what you use

Railway is an infrastructure platform for applications, databases, functions and background jobs. It auto-deploys from a connected GitHub repo, offers database templates including Postgres, MySQL and Redis, and bills per second for the CPU, memory and disk your services actually use.

• Pricing (as of September 2026): Free trial with $5 of one-time credit for 30 days; Free at $0 with $1 of usage a month; Hobby at $5/month including $5 of usage; Pro at $20/month including $20 of usage; custom Enterprise. Usage works out at roughly $10 per GB of memory and $20 per vCPU per month, with egress at $0.05 per GB.
• Strengths: clear per-second billing; quiet apps cost little; easy to add databases alongside your app.
• Limits: a busy app's bill varies month to month, so keep an eye on usage.
• Pick it if you have several small services and want to pay only for what they use.

Fly.io: run close to your users

Fly.io runs code on hardware-isolated virtual machines close to users, in 18+ regions according to its site. Compute bills by the second and storage on what you provision.

• Pricing (as of September 2026): the smallest machine (shared-cpu-1x, 256 MB) is listed at $1.94 a month in its Ashburn region. Managed Postgres starts at $38/month for the Basic plan. Community support is free; paid support plans start at $29/month.
• Strengths: multi-region deployment; very cheap small machines; lots of control.
• Limits: more hands-on than Heroku, and managed Postgres costs more than the entry databases elsewhere.
• Pick it if your users are spread across continents, or you want low-level control at low cost.

DigitalOcean App Platform: simple fixed prices

DigitalOcean App Platform deploys from GitHub or GitLab with automatic HTTPS, custom domains, a CDN and DDoS protection.

• Pricing (as of September 2026): 3 static sites free, each with a 1 GiB data transfer allowance. The smallest paid container is $5/month (1 shared vCPU, 512 MiB). A development database is $7/month.
• Strengths: predictable monthly prices; part of a wider cloud if you later need droplets, managed databases or storage.
• Limits: the free tier covers static sites only.
• Pick it if you want a fixed, low monthly bill for a small app.

Vercel: if it's really a frontend

Vercel is built for frontends and serverless functions, and maintains Next.js. It's not a general home for long-running workers, but many apps that started on Heroku as "a Node app with an API" fit here.

• Pricing (as of September 2026): Hobby is free for personal, non-commercial use; Pro is $20 per developer seat per month with $20 of included usage credit.
• Pick it if your app is mostly a web frontend. See Vercel vs Netlify for how it compares with its closest rival.

Mythex: when you want the app built and hosted

The platforms above host code you already have. Mythex is an AI app builder: you describe what you want in chat, an AI agent writes the code and runs it in a live preview, and you publish to yourname.mythex.ai or, on Pro, your own domain. It can build frontends, APIs (including Node, Python FastAPI, C# or Java with a Dockerfile) and multi-service apps.

• Hosting included: published apps, a dedicated Postgres database per project when needed, and file storage. Apps and databases sleep when idle and wake on the next request. See hosting limits.
• One balance: the same credits pay for building and for hosting. Pro pays half the Free rate for hosting, databases and storage.
• Pricing: Free is $0 with 10 credits a day (up to 30 a month), and you can publish. Pro is $25/month or $250/year.

Where Heroku and the others are better than Mythex: if you already have a codebase, a team and a deploy pipeline, a PaaS is the natural home; Mythex is built around creating and changing apps through chat. The fine-grained controls on Heroku, Fly.io or Render, such as choosing machine types, regions and worker processes, go well beyond what Mythex exposes. Mythex also doesn't document scheduled cron jobs today, and it builds web apps only, not native App Store apps.

How to choose

• Least change from Heroku: Render.
• Pay only for usage, many small services: Railway.
• Global users, low-level control: Fly.io.
• Fixed low monthly bill: DigitalOcean App Platform.
• Mostly a frontend: Vercel or Netlify.
• No code yet, want it built and hosted: an AI app builder like Mythex. See how to build an app with AI.
