Patchlog is a drop-in changelog for web apps. You embed one script tag, with no SDK and no npm install, and get an in-app "what's new" widget plus a hosted changelog page and an RSS feed.

The widget renders inside a Shadow DOM, so it never inherits or leaks the host page's CSS, and it behaves the same in React, Vue, Rails or plain HTML.

Other features: scheduled publishing so you can write updates ahead of time and have them post themselves, per-update view and click analytics, light/dark/auto theming with a custom accent colour on Pro, and 2FA on accounts.

Pricing is flat rather than metered on your traffic: free for 1 project and 25 updates, which shows a small "Powered by Patchlog" badge, or $7/month ($60/year) for unlimited projects and updates, badge removal and advanced analytics. Most tools in this category bill per monthly active user, so the bill grows with your app even though writing release notes does not get harder.

What Patchlog does not do: no user segmentation or targeting, no NPS surveys, no roadmaps or feature voting boards, no email digests, and no public API. If you need those, Beamer or Canny is the better fit.

Packer features and specs

  • Multi-Provider Support
    Packer supports a wide variety of providers such as AWS, Azure, Google Cloud, VMware, and more. This allows for flexibility and the ability to create machine images across different environments.
  • Automation
    Packer automates the creation of machine images, eliminating the need for manual image configuration and reducing the potential for human error.
  • Script Reusability
    Packer allows for the reuse of scripts and configuration files, enabling a consistent and repeatable process for image creation.

Possible disadvantages of Packer

  • Steep Learning Curve
    The variety of features and flexibility that Packer offers can make it complex and challenging to learn, especially for beginners.
  • Limited Debugging Tools
    Packer's debugging tools are not as mature or as integrated as those found in some other DevOps tools, making troubleshooting more difficult.
  • Configuration Complexity
    Complex configurations with multiple builders and provisioners can become hard to manage and maintain, leading to potential errors.
  • No State Management
    Unlike Terraform, Packer does not manage state, which means users need to handle state management separately if required.
  • Dependency on External Tools
    Packer often relies on external scripts and tools for provisioning, which can introduce additional dependencies and complexities.

Questions & Answers

As answered by people managing Packer and Patchlog.

What makes your product unique?

Patchlog's answer:

A real free plan with no trial expiry, and a widget that embeds in any web app with two lines of JavaScript. No bloated feature set, no enterprise pricing for a tool that should be simple.

Why should a person choose your product over its competitors?

Patchlog's answer:

Most changelog tools charge $29-$60/month for features most small teams never use. Patchlog gives you a working in-app widget, a public SEO-friendly changelog page, full Markdown support, and RSS on the free plan. The Pro plan is $5/month. It covers everything 90% of SaaS products actually need.

How would you describe the primary audience of your product?

Patchlog's answer:

Indie founders, solo developers, and small SaaS teams who want to keep users informed about product updates without paying enterprise prices for it.

What's the story behind your product?

Patchlog's answer:

Built out of frustration with the existing options. Every changelog tool was either too expensive, too complex, or offered a "free trial" that expired before you could evaluate it properly. Patchlog started as the tool we wished existed: simple to embed, honest free tier, no fluff.

Which are the primary technologies used for building your product?

Patchlog's answer:

Laravel, Vue 3, Inertia.js, Tailwind CSS, MySQL.

Who are some of the biggest customers of your product?

Introduction to Top Open Source Virtualization Tools
Packer is notably light, high performing, and operates on every major operating system. It assembles and configures all the necessary components for a virtual machine then creates images that run on multiple platforms. Packer doesnโ€™t replace configuration management tools like Puppet or Chef; as a matter of fact, when creating images, Packer can utilize tools like Puppet or...

  • Failed to connect to the host via SSH on Ubuntu 22.04
    If you have just upgraded to Ubuntu 22.04, and you suddenly experience either errors when trying to ssh into hosts, or when running ansible or again when running the ansible provisioner building a packer image, this is probably going to be useful for you. - Source: dev.to / almost 4 years ago
  • Create a minimalist OS using Docker Containers and Hashicorp Packer
    I am already using Hashicorp Packer at work and for personal projects and I wanted to test This idea out by wrapping it a single Packer Template file. This reduces the level of maintaining a lot of small scripts, Dockerfiles and configurations and the user can simply trigger a couple of Commands to get a minimalist OS at the end of the process. - Source: dev.to / almost 4 years ago
  • After self-hosting my email for twenty-three years I have thrown in the towel. The oligopoly has won.
    And while it is a slight increase in complexity, it can be an overall net gain in functionality, configurability and reliability. Much like Packer is far more reliable and practical than manually making VM images sitting in front of a terminal, even though making the initial configuration takes some time. Source: almost 4 years ago
  • Customized Ubuntu Images using Packer + QEMU + Cloud-Init & UEFI bootloading
    Hashicorp Packer provides a nice wrapper / abstraction over the QEMU in order to boot the image and use it to set it up on first-boot. Instead of writing really long commands in order to boot up the image using QEMU, Packer provided a nice Configuration Template in a more Readable fashion. - Source: dev.to / almost 4 years ago
  • The journey of sharing a wired USB printer over the network
    Packer seemed like the perfect tool for the job. I have never used it before and wanted to get familiar with the tool. It doesn't come with ARM support out of the box, but there are two community projects to fill that niche. - Source: dev.to / over 4 years ago

  • How to embed a widget on any site without CSS collisions (Shadow DOM)
    This is exactly how I built the changelog widget for Patchlog. It is a drop-in "what's new" widget for SaaS products: one script tag, rendered inside a Shadow DOM so it never collides with the host site's CSS, with light, dark, and auto theming that reads the host's CSS variables when you want it to. There is a free tier if you want to see the technique in a shipped product rather than a blog snippet. - Source: dev.to / 24 days ago
  • How to add a changelog to any web app with one script tag
    I build Patchlog, so the snippet above is my own tool. I'm not going to pretend otherwise. It's early: the free tier is one project and 25 updates, which is genuinely what I run on my own projects. I'm sharing the approach because it's helped me, and if it saves you the afternoon it cost me to think through, great. - Source: dev.to / 25 days ago
