    free-for.dev

    free-for.dev

    A list of SaaS, PaaS and IaaS offerings that have free tiers

    free-for-dev is a long-running, community-curated catalog of services that offer free tiers useful to developers, students, makers, and small teams. The list spans hosting, databases, CI/CD, monitoring, source control, APIs, design tools, and more, organized into clear categories so readers can scan and compare options quickly. It emphasizes practical limits such as usage caps, seat counts, rate limits, and time-boxed trials, helping users spot real-world constraints before adopting a tool. The repository is maintained via pull requests and issue discussion, so new services and policy changes can be incorporated as providers evolve their offerings. Contributors often include short notes or caveats next to each entry, which keeps the list actionable rather than just promotional. Because it’s a single, searchable markdown resource, it has become a go-to reference for bootstrappers and engineers looking to prototype or run small workloads at minimal cost.

    PaaSTA

    PaaSTA

    An open, distributed platform as a service

    PaaSTA is a highly-available, distributed system for building, deploying, and running services using containers and Kubernetes. PaaSTA has been running production services at Yelp since 2016. It was originally designed to run on top of Apache Mesos but has subsequently been updated to use Kubernetes. Over time the features and functionality that PaaSTA provides have increased but the principal design remains the same. PaaSTA aims to take a declarative description of the services that teams need to run and then ensures that those services are deployed safely, efficiently, and in a manner that is easy for the teams to maintain. Rather than managing Kubernetes YAML files, PaaSTA provides a simplified schema to describe your service and in addition to configuring Kubernetes it can also configure other infrastructure tools to provide monitoring, logging, cost management etc.

    Minishift

    Minishift

    Run OpenShift 3.x locally

    Minishift is a tool that helps you run OpenShift locally by running a single-node OpenShift cluster inside a VM. You can try out OpenShift or develop with it, day-to-day, on your local host. Minishift requires a hypervisor to start the virtual machine on which the OpenShift cluster is provisioned. Make sure that the hypervisor of your choice is installed and enabled on your system before you start Minishift. Minishift documentation is published as a part of the OpenShift Origin documentation library. Check out the latest official Minishift documentation for information about getting started, using, and contributing to Minishift.

    Octelium

    Octelium

    A next-gen FOSS self-hosted unified zero trust secure access platform

    Octelium is an open source, self-hosted unified secure-access platform built for modern infrastructure and hybrid environments. It positions itself as more than a typical VPN; it supports zero-trust network access (ZTNA), “BeyondCorp”-style access, API/AI gateway functionality, and even serves as a PaaS-like deployment surface. One of its key strengths is identity-based, application-layer (L7) aware control, meaning access decisions are made per request, with context and policy rather than simple network-level allow/block rules. It supports both client-based (e.g., WireGuard/QUIC tunnels) and client-less access models, which makes it flexible for both human users and automated workloads. The project also highlights self-hosted, no hidden “server-side” locked components, giving organizations greater ownership and control over access, rather than relying on proprietary SaaS.

    Convox Rack

    Convox Rack

    Private PaaS built on native AWS services for maximum privacy

    Convox Rack is a private PaaS that runs inside a user’s AWS account and provides a managed application deployment layer over cloud infrastructure. It is designed for teams that want the productivity of a platform-as-a-service while keeping workloads, data, and infrastructure under their own control. Developers interact with Rack through the Convox CLI to create apps, set environment variables, deploy code, build releases, and promote updates. The platform handles application lifecycle tasks such as releases, logs, processes, scaling, rack updates, access credentials, and operational configuration. It also exposes commands for inspecting rack processes and generating Kubernetes configuration for the underlying cluster. Convox Rack is especially useful for teams that want repeatable deployments, cloud-native isolation, and reduced infrastructure maintenance without moving everything into a fully managed third-party runtime.

    Empire

    Empire

    A PaaS built on top of Amazon EC2 Container Service (ECS)

    Empire is a control layer on top of Amazon EC2 Container Service (ECS) that provides a Heroku-like workflow. It conforms to a subset of the Heroku Platform API, which means you can use the same tools and processes that you use with Heroku, but with all the power of EC2 and Docker. Empire is targeted at small to medium-sized startups that are running a large number of microservices and need more flexibility than what Heroku provides. You can read the original blog post about why we built Empire on the Remind engineering blog. Empire aims to make it trivially easy to deploy a container-based microservices architecture, without all of the complexities of managing systems like Mesos or Kubernetes. ECS takes care of much of that work, but Empire attempts to enhance the interface to ECS for deploying and maintaining applications, allowing you to deploy Docker images.

    Kubernetes powered PaaS that runs in your own cloud

    Porter is a fully-managed PaaS that lets teams automate DevOps. Deploy and manage apps within AWS, GCP, DO, and more. Porter manages and scales services in your existing cloud so you can focus on building products. Deploy in seconds from a Git repo or Docker registry. Porter simplifies service management while still offering the flexibility of a fully-featured DevOps platform when you need it. Use your existing AWS, GCP, or DO cloud as a hosting backend. They host your apps, Porter manages them. Automate your cloud management and focus on what matters. A traditional PaaS like Heroku is great for minimizing unnecessary DevOps work but doesn't offer enough flexibility as your applications grow. Custom network rules, resource constraints, and cost are common reasons developers move their applications off Heroku beyond a certain scale. Porter brings the simplicity of a traditional PaaS to your own cloud provider while preserving the configurability of Kubernetes.

It works with popular Rust web frameworks such as Axum, Actix Web, and Rocket. Shuttle also handles infrastructure concerns like permissions and security so developers can focus on application logic. Its repository includes the Shuttle CLI, runtime, services, resource integrations, examples, and deployment-related tooling. The GitHub repository is currently archived and read-only, but it remains a useful reference for the platform’s architecture and Rust deployment model.
