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.

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.

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.

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.
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.
A container platform that needs no Kubernetes learning
Rainbond is an open-source container platform that helps teams build, deploy, upgrade, operate, and deliver applications on Kubernetes without requiring deep Kubernetes expertise. It focuses more on application delivery than low-level cluster resource management. The platform brings source code, container images, templates, dependencies, access management, upgrades, and rollbacks into a standardized graphical workflow. Rainbond is built for complex enterprise delivery scenarios such as private deployment, offline delivery, internal-network environments, Xinchuang adaptation, ARM migration, and AI application privatization. It includes marketplace and template capabilities so teams can reuse applications and replicate deployments across customer environments. Its goal is to let development and delivery teams work at the application level while platform teams handle the underlying Kubernetes complexity.
Build & ship backends without writing any infrastructure files
Shuttle is a Rust-focused backend deployment platform designed to help developers build and ship applications without writing infrastructure configuration files. It lets projects provision resources such as databases directly from application code, removing the need for separate YAML or cloud setup workflows.
