5 Open Source Alternatives To Heroku

Coolify is an open-source and self-hostable alternative to platforms like Heroku, Netlify, and Vercel. It allows you to deploy and manage your applications seamlessly across various environments, giving you the freedom and control to host on your own terms. Compatible with a wide range of programming languages and frameworks, Coolify makes it easy to launch static websites, APIs, backends, databases, services, and more. You can deploy resources to any server with an SSH connection, including your own servers, VPS, Raspberry Pi, EC2, DigitalOcean, Linode, Hetzner, and more. Coolify also supports deployment to multiple servers or Docker Swarm clusters, with Kubernetes support on the way. Git integration is built-in, supporting both hosted and self-hosted platforms like GitHub, GitLab, Bitbucket, and Gitea. Coolify automates the setup and renewal of Let's Encrypt SSL certificates for your custom domains. All settings are saved on your own servers, ensuring you have complete control over your data. Your data is automatically backed up to any S3-compatible solution, allowing for easy restoration if needed. You can integrate Coolify into your CI/CD pipelines using tools like GitHub Actions, GitLab CI, and Bitbucket Pipelines. The robust API enables automation of deployments, management of resources, and integration with existing tools. Team collaboration is made easy with project sharing, permission control, and role management. Coolify automates numerous tasks once your server is connected, letting you focus on your code. It monitors deployments, servers, disk usage, and more, notifying you of any issues through your chosen channels like Discord, Telegram, or email.

OpenFaaS makes it simple to deploy both functions and existing code to Kubernetes. It allows you to run your code anywhere with a unified experience, whether on-premises or in the cloud, using portable OCI images.

• Anywhere: Deploy your functions on-premises or in the cloud, with portable OCI images.
• Any code: Write functions in any language, and bring your existing microservices along too.
• Any scale: Pro features scale your functions to meet demand, and down to zero when idle.
• Efficient scaling: Your functions can be fine-tuned to scale to match the type of traffic they receive, including to zero to save on costs.
• Event-driven workloads: Invoke functions through events from Apache Kafka, AWS SQS, Postgresql, Cron, and MQTT.
• Multi-tenancy: Supported through Kubernetes network policies, resource limits, runtime classes, read-only filesystems, and dedicated namespaces per tenant.
• Batch jobs and ML models: Deploy and scale batch jobs and machine learning models as functions, even for long-running tasks.
• Language support: Functions can be written in any language and are built into portable Open Container Initiative (OCI) images with tooling like Docker & Buildkit.

OpenFaaS enriches Kubernetes with scaling, queueing, monitoring, and event triggers, so your team can focus on shipping features. It is trusted in production by companies like Waylay, Patchworks, LivePerson, and Cognite for various use cases including custom functions for industrial IoT, customer extensions for e-commerce, and custom ML/data-science functions.
