Self-hosted alternatives: Ultimate guide to cheaper SaaS

In the following ultimate guide, we'll cover dozens of self-hosted alternatives to oftentimes expensive Software-as-a-Service (SaaS) web apps that you probably pay for on a monthly basis. By leveraging the power of your SSD Nodes VPS, you can run dozens of web apps and services for a fraction of the cost—you might even be able to completely negate the cost of your VPS. Plus, you get more customization and retain full control of your data.

All of these options are open source and free to use. A few have paid options for enterprises or those who need a managed experience or dedicated customer support, but there is always a free tier that you can download and install on your VPS.

If you're curious about what self-hosting is, be sure to check out our guide on the subject. For a comprehensive guide into creating your own self-hosting infrastructure, complete with HTTPS and the portability of Docker containers, read our definitive self-hosting handbook. This handbook

Blogs/content management systems

Self-hosted WordPress, naturally, is already a leader in this space, but other popular options include Squarespace, Medium, and Tumblr.

Self-hosted email is a difficult category to pin down, as there's so many different components that go into feature-complete email system. Instead of trying to focus on all of the individual components—MTAs, SMTP servers, IMAP, webmail, and mailing list software—we're going to focus more on complete solutions that try to offer everything in one package.

Naturally, Gmail is the leader in this space.

Project management

micro-analytics: "Public analytics as a Node.js microservice, no sysadmin experience required."

Piwik: "Piwik is the leading open alternative to Google Analytics that gives you full control over your data."

Code repositories

For years, GitHub has been the primary place to host public or private GitHub repositories—for many the built-in community (stars, following developers) is a bonus. For those who don't want or need those features, or want to keep code completely secure, self-hosted is a viable option.

cgit: "A hyperfast web frontend for git repositories written in C."

Text/Markdown editors

Dillinger: "Radicale is a free and open-source CalDAV and CardDAV server."

Codiad: "Codiad is a web-based IDE framework with a small footprint and minimal requirements."

HackMD: "HackMD lets you create realtime collaborative markdown notes on all platforms. Inspired by Hackpad, with more focus on speed and flexibility."


Leanote: "Not Just A Notepad! (golang + mongodb)"


There truly is no one dominant solution for backups, particularly backing up the content of a VPS. In this list, we cover solutions that are installed on the VPS and then connect to external backup storage.

bareos: "Bareos is a 100% open source fork of the backup project from"

Borg: "Deduplicating archiver with compression and authenticated encryption."

UrBackup: "UrBackup is an easy to setup Open Source client/server backup system, that through a combination of image and file backups accomplishes both data safety and a fast restoration time."

RSS readers

Google Reader lives on in our hearts, and Feedly has done its best to fill the empty void. That said, many people miss the days of FeedBurner and other barebones tools that didn't get in the way of delivering RSS feeds.

Miniflux: "Minimalist web RSS reader."

NewsBlur: "NewsBlur is a personal news reader that brings people together to talk about the world. A new sound of an old instrument."

While many people use the bookmarking and synchronization features built into most modern-day browsers, others choose cloud services like Pocket or Instapaper.

bookmarks: "a simple self-hosted bookmarking app that can import bookmarks from delicious or chrome"

Firefox Sync Server: "This is an all-in-one package for running a self-hosted Firefox Sync server. It bundles the 'tokenserver' project for authentication and the "syncstorage" project for storage, produce a single stand-alone webapp."

Fresh RSS: "FreshRSS is a self-hosted RSS feed aggregator such as Leed or Kriss Feed. It is at the same time lightweight, easy to work with, powerful and customizable."

Commenting systems

Aside from commenting systems that are built directly into content management systems, Disqus is the leader in this space.

commento: "A lightweight, open source, tracking-free comment engine alternative to Disqus."

HashOver: "HashOver is a PHP comment system intended as a replacement for services like Disqus."

isso: "A Disqus alternative."

Time tracking

Freelancers are probably aware of Toggl and Harvest, two of the more popular time tracking options.
