When the topic of Platform as a Service i.e. PaaS is discussed, Heroku is surely to be mentioned. Heroku gained the popularity as a PaaS in the beginning of late 2010s, mainly due to it’s free tier offerings. The student developers, small startups, freelancer developers contributed in its growth, more specifically after the introduction of ‘Free Dynos’ in 2013. It’s effective pricing policy and the lenient limitations of the free plan made it the first choice for developing and deploying the apps with the developers worrying about database management, server management, Git control, and other such tasks which takes a toll on the developers while they should be focusing on the actual development of the applications.

Heroku does present exceptional offerings and services as a PaaS.

  • Horizontal and vertical scalability of dynos to support both increasing web requests as well as the performance load.

  • Support for almost all the leading development languages and frameworks such as Node.js, Ruby, Python, Java, PHP, Go, Scala, and so on.

  • Web, worker, and one-off dynos to serve web requests, run background tasks and asynchronous process, execute short-lived tasks such as database migration respectively.

  • Fully managed PostgreSQL database service in the form of Heroku Postgres.

  • Heroku add-ons that attach to the applications to extend functionality.

  • Heroku pipelines to effectively manage various stages of the application development with a possibility to setup multiple environments.

  • Automatic adjustments or scaling of the dynos with the Auto-scaling feature.

Heroku offers aforementioned services but, doesn’t limit to these. Explore the offerings of Heroku by connecting with a web development company which users Heroku on for all the projects.

Until 2022, things were going fine between the Heroku and the developers when the whole crypto-wave swept the globe and there were instances of Heroku’s free dynos were used for illegal mining and spamming by the bad actors. As a response, Heroku decided to phase out from the free tier while keeping the charges to a moderate level.

It is at this point, the developer community across the globe started to look for a reliable alternative to Heroku. We being into web development services, too started looking for alternatives but, it was difficult to find information about all the alternatives at one place and a direct comparison with Heroku which assist in knowledged decision making. Hence, we would like to present our curated list of 7 best alternative to Heroku.

Fly.io

Fly.io is designed for running full-stack applications with a focus on global distribution. Deploy your app across multiple regions and closer to your users, to reduce latency and improve performance. Fly.io uses lightweight VMs (Firecracker) for running applications and supports low-latency, geo-distributed deployments. Fly.io is optimized for running apps at the edge, meaning your app can be served close to where the request originates. Unlike Heroku’s dynos, Fly.io uses Firecracker microVMs, which are lightweight and highly performant for fast booting and running apps at scale.

Both Fly.io and Heroku offer the pay-as-you-go model. Where Heroku starts with $0.005/hour, Fly.io starts from $0.027/hr which is almost half the price of Heroku making it to appear first on the list.

Render

Render also uses a containerized deployment model but simplifies it further by automating tasks like SSL certificates, domain management, and zero-downtime deployments. Render offers custom domains for free, even in the free tier, while Heroku requires paid plans for custom domain support. Render offers an even more automated approach by removing the need for third-party add-ons in many cases. Render includes many of the features that would be add-ons in Heroku such as SSL, custom domains, managed databases, background workers, and DDoS protection as built-in services.

While on one hand Heroku doesn’t have a completely free plan, Render offers a free plan for Static sites at least.

Linode

Though Linode is an Infrastructure as a Service rather than a PaaS similar to Heroku, it offers raw virtual machines (VMs) or virtual private servers (VPS) where developers or system administrators can deploy any kind of software or service. It is for those who need more control and flexibility in configuring their own servers and environments. As opposed to Heroku, it requires more technical know-how because it provides a raw server environment. Linode provides full virtual machines, giving you direct access to CPU, RAM, and storage. You have more flexibility in how you configure and use resources.

Linode is generally cheaper than Heroku when it comes to raw compute power, but you need to manage everything yourself.

Vercel

Vercel Vercel primarily focuses on Frontend and Jamstack applications and is optimized for hosting static websites and serverless functions. While build for Next.js appications initially, it supports other software frameworks like React, Vue.js, Svelte, etc. Vercel provides zero-configuration deployments for frontend apps and comes with built-in performance optimizations. As opposed to Heroku where the requirement of scaling is to be monitored, Vercel automatically scales serverless functions on demand, handling spikes in traffic without needing to manually configure scaling.

Compared to Heroku, Vercel offers a free plan to kickstart the web project and includes almost all the features required to efficiently run a small scale website.

Netlify

Netlify** is for frontend-heavy or static apps, specializing in static site hosting and serverless functions. If focuses on static hosting and deploying serverless functions. It’s best for Jamstack architecture where the frontend is decoupled from the backend. Unlike Heroku which requires configuration or add-ons, Netlify has automatic SSL certificates and global CDN included by default. It’s optimized for deploying static sites, SPAs (Single Page Applications), and serverless functions.

Similar to Vercel and Render and unlike Heroku, Netlify offers free plans to get your work started with decent set of features in the free plan.

DigitalOcean

Similar to Linode, DigitalOcean is an IaaS (Infrastructure as a Service) offering virtual private servers (called Droplets), databases, object storage, and other infrastructure-related services. Like Heroku has dynos, DigitalOcean offers tools like Droplets, Managed Databases, and Kubernetes clusters, but these require some level of expertise to configure properly. DigitalOcean is suitable for deploying virtual servers, databases, Docker containers, and even Kubernetes clusters. Similar to horizontal and vertical scaling in Heroku, you can scale by upgrading Droplets (virtual machines) or adding more resources manually.

DigitalOcean’s Droplets are significantly cheaper than Heroku’s dynos, but you’re responsible for the setup and scaling.

Railway.app

Railway.app is a cloud development platform that focuses on infrastructure-as-code, aiming to make infrastructure management invisible to the developer. Railway is highly developer centric and emphasizes on auto-scaling, auto-deployments, and flexibility. It provides an environment with auto-scaling, logs, and metrics out-of-the-box without needing manual setup. Unlike Heroku, Railway handles auto-scaling by default. It automatically adjusts resources based on traffic and workload without manual intervention.

Pricing starts at $5 per month based on resource usage. Railway charges based on the actual resources used.

Conclusion

Heroku has long been a popular choice for developers looking for an easy-to-use PaaS solution, especially with its free tier in the past, the recent shift in its pricing model has encouraged many to explore alternatives. The seven platforms discussed - Fly.io, Render, Linode, Vercel, Netlify, DigitalOcean, and Railway.app - each offer unique features that cater to different development needs, whether you're seeking better pricing, more control, enhanced performance, or automated scaling.
