Static Analysis Is Broken - Let’s Fix It!

8/19/2020 by Matthias Endler

Static analysis is great! It helps improve code quality by inspecting source code without even running it. There are hundreds of great tools to choose from — many are free or open-source. Unfortunately, many projects still don’t make use of static analysis tools for various reasons.

Our mission is to fix that by building an open platform for comparing static analysis tools. All code is open-source and backed by the community. We’re proud to count 192 individual contributors on Github so far. With this website, we aim to make static analysis accessible to even more people.

What Is Static Analysis?

Wouldn’t it be great to find bugs and fix issues automatically? What if you could fix most problems during development instead of production? There are great tools for that!

Those static analysis tools can be grouped into different categories:

  • Formatters: these apply a predefined code-style automatically and make your code consistent and pretty
  • Linters: detect bugs and code smells
  • Metalinters: combine many linters into one tool

Even within each category, there are more ways to group the tools. For example, you could split them into rule-based or AST-based (and perhaps machine-learning-based-) tools.

There are also different ways to incorporate those tools into your workflow:

  • Online services that get added to continuous integration pipelines
  • Command-line tools
  • IDE-plugins

It is a huge space for different services and approaches that is surprisingly tricky to organize, which leads to some problems.

Cargo Cult?

Wisdom about code analysis tools is spread all over the place: websites, blog posts, forums, videos,… there is no quick and easy way to compare tools and learn about them.

This lack of information leads to a strange dogma around static analysis: it is seen as an overly academic topic by some and gets worshiped as the holy grail by others.

There almost seems to be a weird cargo-cult around some tools, even though they have long been deprecated and superseded by more powerful successors. For example, JSLint is heavily debated by the community. You might be better off using eslint for new projects these days.

We provide an easy way to answer the following questions:

  • Is this the best tool for my use-case?
  • Is it still maintained?
  • Is the license acceptable?
  • Where can I find more information?

With that, we hope to demystify static analysis a bit.

Most Public Lists Are Outdated

If you search for “static analysis” on Google, chances are, you end up on this list on Wikipedia. It provides a list of static analysis tools, and it’s arguably the first contact point with static analysis for many people. It’s an honest first attempt, but quite frankly, its quality is poor for many reasons:

  • The number of tools on the list is small: About 130 are listed, but many hundred more exist.
  • It’s outdated: Many modern/powerful tools are missing.
  • Inconsistent formatting: A mixture of tables and unordered lists make comparison unnecessarily hard.
  • No way to filter tools by license or programming language
  • Contains outdated external links (yep, we checked)
  • The license is missing for many tools

Instead, we put a lot of effort into consistent structure and work on better filtering functionality. We have tooling in place to make sure that all information is up-to-date.

All Static Analysis Tools Get Lumped Together

Remember the categories from above? To most websites, it’s all linters. That doesn’t help if you’re looking for a formatter or a machine-learning-based SAAS service for your CI pipeline. It’s very time-consuming and tedious to wade through a sea of websites, so people rarely do. It’s like ten thousand spoons when all you need is a knife. (It’s ironic if you didn’t get that reference.)

No Fair Comparison Between The Tools

Most companies just try to sell. The loudest voice on the market wins - not the best tool. More niche projects that would be a better fit are hard to find.

It’s difficult to find out what the “community-endorsed” set of standard tools is. Therefore we support votings and discussions and work together with the developer communities to make discovery easier.

An Open Platform

The aim of is to be a sharp tool that you use by choice. That’s why we build this project entirely in the open to avoid bias and gatekeepers, which promote tools purely based on monetary interest and not on quality. Our mission is to establish as a platform for comparing analysis tools, and we are committed to keep the site up-to-date and add features like video workshops in the future.


Let us take the time to thank our first sponsor, DeepCode.

It is a real-time semantic code analysis service that is deeply rooted within the open-source community. They provide their service free of charge for open source — forever. You should go check out their site. It is great to see companies like DeepCode embrace open source and work with the community to establish higher standards for code quality.

We would also like to thank all contributors on Github that helped get us to reach that milestone. You all deserve a special place in our hearts.


Help make this possible offers a lot for free, but of course, it is not free to operate or develop. If it provides value for you or your company and you wish to support its development, consider donating on Github Sponsors.

Our Mission

❤️ Reach Thousands Of Devs Interested In Code Quality

That's why we are currently looking for partners who want to sponsor hosting and development of the project.

We believe that this project should be entirely open to avoid bias and gatekeepers, which promote tools purely based on monetary interest and not on quality. Since we want this to be a community project and the code/assets to be freely available to everyone, we'll use Github Sponsors + Open Collective for funding.
