them all takes time to make informed decisions.\n\nThis is a list of software (SaaS, PaaS, IaaS, etc.) and other offerings with free developer tiers.\n\nThe scope of this particular list is limited to things that infrastructure developers (System Administrators, DevOps Practitioners, etc.) are likely to find useful. We love all the free services out there, but it would be good to keep it on topic. It's a grey line sometimes, so this is opinionated; please don't feel offended if I don't accept your contribution.\n\nThis list results from Pull Requests, reviews, ideas, and work done by 1600+ people. You can also help by sending [Pull Requests](https://github.com/ripienaar/free-for-dev) to add more services or remove ones whose offerings have changed or been retired.\n\n[![Track Awesome List](https://www.trackawesomelist.com/badge.svg)](https://www.trackawesomelist.com/ripienaar/free-for-dev)\n\n**NOTE**: This list is only for as-a-Service offerings, not for self-hosted software. To be eligible, a service must offer a free tier, not just a free trial. The free tier must be for at least a year if it is time-bucketed. We also consider the free tier from a security perspective, so SSO is fine, but I will not accept services that restrict TLS to paid-only tiers.\n\n# Table of Contents\n\n  * [Major Cloud Providers' Always-Free Limits](#major-cloud-providers)\n  * [Cloud management solutions](#cloud-management-solutions)\n  * [Analytics, Events, and Statistics](#analytics-events-and-statistics)\n  * [APIs, Data and ML](#apis-data-and-ml)\n  * [Artifact Repos](#artifact-repos)\n  * [BaaS](#baas)\n  * [Low-code Platform](#low-code-platform)\n  * [CDN and Protection](#cdn-and-protection)\n  * [CI and CD](#ci-and-cd)\n  * [CMS](#cms)\n  * [Code Generation](#code-generation)\n  * [Code Quality](#code-quality)\n  * [Code Search and Browsing](#code-search-and-browsing)\n  * [Crash and Exception Handling](#crash-and-exception-handling)\n  * [Data Visualization on Maps](#data-visualization-on-maps)\n  * [Managed Data Services](#managed-data-services)\n  * [Design and UI](#design-and-ui)\n  * [Dev Blogging Sites](#dev-blogging-sites)\n  * [DNS](#dns)\n  * [Docker Related](#docker-related)\n  * [Domain](#domain)\n  * [Education and Career Development](#education-and-career-development)\n  * [Email](#email)\n  * [Feature Toggles Management Platforms](#feature-toggles-management-platforms)\n  * [Font](#font)\n  * [Forms](#forms)\n  * [Generative AI](#generative-ai)\n  * [IaaS](#iaas)\n  * [IDE and Code Editing](#ide-and-code-editing)\n  * [International Mobile Number Verification API and SDK](#international-mobile-number-verification-api-and-sdk)\n  * [Issue Tracking and Project Management](#issue-tracking-and-project-management)\n  * [Log Management](#log-management)\n  * [Mobile App Distribution and Feedback](#mobile-app-distribution-and-feedback)\n  * [Management Systems](#management-system)\n  * [Messaging and Streaming](#messaging-and-streaming)\n  * [Miscellaneous](#miscellaneous)\n  * [Monitoring](#monitoring)\n  * [PaaS](#paas)\n  * [Package Build System](#package-build-system)\n  * [Payment and Billing Integration](#payment-and-billing-integration)\n  * [Privacy Management](#privacy-management)\n  * [Screenshot APIs](#screenshot-apis)\n  * [Flutter Related and Building IOS Apps without Mac](#flutter-related-and-building-ios-apps-without-mac)\n  * [Search](#search)\n  * [Security and PKI](#security-and-pki)\n  * [Authentication, Authorization, and User Management](#authentication-authorization-and-user-management)\n  * [Source Code Repos](#source-code-repos)\n  * [Storage and Media Processing](#storage-and-media-processing)\n  * [Tunneling, WebRTC, Web Socket Servers and Other Routers](#tunneling-webrtc-web-socket-servers-and-other-routers)\n  * [Testing](#testing)\n  * [Tools for Teams and Collaboration](#tools-for-teams-and-collaboration)\n  * [Translation Management](#translation-management)\n  * [Visitor Session Recording](#visitor-session-recording)\n  * [Web Hosting](#web-hosting)\n  * [Commenting Platforms](#commenting-platforms)\n  * [Remote Desktop Tools](#remote-desktop-tools)\n  * [Other Free Resources](#other-free-resources)\n\n## Major Cloud Providers\n\n  * [Google Cloud Platform](https://cloud.google.com)\n    * App Engine - 28 frontend instance hours per day, nine backend instance hours per day\n    * Cloud Firestore - 1GB storage, 50,000 reads, 20,000 writes, 20,000 deletes per day\n    * Compute Engine - 1 non-preemptible e2-micro, 30GB HDD, 5GB snapshot storage (restricted to certain regions), 1 GB network egress from North America to all region destinations (excluding China and Australia) per month\n    * Cloud Storage - 5GB, 1GB network egress\n    * Cloud Shell - Web-based Linux shell/primary IDE with 5GB of persistent storage. 60-hour limit per week\n    * Cloud Pub/Sub - 10GB of messages per month\n    * Cloud Functions - 2 million invocations per month (includes both background and HTTP invocations)\n    * Cloud Run - 2 million requests per month, 360,000 GB-seconds memory, 180,000 vCPU-seconds of compute time, 1 GB network egress from North America per month\n    * Google Kubernetes Engine - No cluster management fee for one zonal cluster.
