Google's SRE books. Microsoft's For Beginners series. GitLab's company-wide handbook. Big tech companies publish enormous amounts of educational content for free. But the form is quite different from the annual "training material release" tradition of Japanese tech companies.
Outside Japan, you almost never see a blog post titled "here are this year's new-grad training materials." Instead, companies open source entire curricula, publish their internal playbooks as books, or build full education platforms around their own technologies.
This article curates the most notable free materials by category, then digs into why the shape of corporate education differs so much between Japan and everywhere else. Combined with the Japanese companies' materials, the amount you can learn for free is remarkable.
There is no "training material release" culture outside Japan
Start with the structural difference. Japan's training releases are a product of batch hiring: every April, a cohort of new graduates joins at once and gets trained together, so a systematic curriculum gets produced in-house every year, and many companies publish it.
Most tech companies elsewhere have no such structure. Hiring is year-round and per-role, and onboarding happens within teams. The artifact "this April's complete training curriculum" simply does not exist.
Interestingly, materials born from internal training do exist. Twitter's Scala School began as a series of internal lectures to turn experienced engineers into productive Scala programmers, and was published as-is. Google's Machine Learning Crash Course was originally internal training for Google engineers, with more than 18,000 employees enrolled before its public release in 2018. Same idea as Japan's releases, but as one-off launches rather than an annual ritual.
So what forms does big tech education actually take? Broadly, three.
The best free learning materials from big tech
Entire curricula, published as open source
Courseware published on GitHub and similar platforms, free for anyone to learn from (and contribute to).
| Company | What they publish |
|---|---|
| Microsoft | "Web Dev for Beginners" (24 lessons over 12 weeks, over 96,000 GitHub stars), plus a whole For Beginners series covering ML, AI, data science, generative AI, IoT, and cybersecurity |
| Amazon | Materials from Machine Learning University (MLU), Amazon's internal ML education program. MLU-Explain teaches core ML concepts through interactive visual essays |
| Machine Learning Crash Course. Built as internal training, opened to the public in 2018, used by millions since, and recently reworked to cover LLMs | |
| Scala School, the pioneering example: an internal lecture series for training engineers in Scala, published for everyone | |
| Jane Street | OCaml workshop exercises where you build games like Snake and Frogger, published under the Apache-2.0 license |
Internal knowledge and ways of working, published
Not technical curricula, but the practices and organizational knowledge companies developed internally, released as books and handbooks.
| Company | What they publish |
|---|---|
| Three SRE (Site Reliability Engineering) books, free to read in full, plus the internal code review guidelines under a CC license | |
| GitLab | A huge public handbook documenting how the entire company runs: hiring, compensation, engineering processes, everything |
| Valve | The new employee handbook (PDF) explaining how to work in a company with no bosses, famous since its release |
| 37signals | "Shape Up," their product development methodology, free to read in full and widely referenced for its six-week cycle approach |
Ecosystem education for their own technology
Education content built to product-level quality, teaching the company's own technology for free. Outside Japan, this is where the real volume is.
| Company | What they publish |
|---|---|
| Salesforce | Trailhead, a gamified free learning platform with badges and ranks, used by millions and feeding into 60+ certifications |
| GitHub | GitHub Skills, official courses where you learn GitHub by doing, inside real repositories |
| Atlassian | The Git tutorials, a definitive series covering Git from internals to workflows, and the landing spot for countless Git searches worldwide |
| MongoDB | MongoDB University, free database courses and certifications |
| Apple | Official tutorials for SwiftUI and beyond, teaching Apple platform development by building sample apps |
"Free to read" and "free to reuse" are different things here too. Licenses vary from open source (Apache, CC) to standard site terms, so check each resource's conditions before redistributing or adapting them.
Why the shape differs from Japan
Same idea, giving education away for free, yet completely different forms. Three structural reasons explain it.
Ecosystem strategy is the main event
By sheer volume, the third category, teaching your own technology, dominates. This is not charity; it is core business strategy.
Salesforce built a pipeline where people who learn on Trailhead become "Salesforce admins" and "Salesforce developers" by profession. The more people know the product, the more companies can adopt it, and the market itself grows. Atlassian's Git tutorials work the same way: engineers worldwide search for Git, land on Atlassian's site, and some become Jira and Bitbucket customers. The education content is designed as a product that does marketing, hiring, and market expansion at once.
Where Japanese training releases aim mainly at recruiting brand, overseas education investment centers on growing the user base of the company's own technology.
Publishing your philosophy builds the brand
Google's SRE books are not just an operations manual. They made "SRE" itself, the role and the methodology, an industry standard. Companies worldwide now run SRE teams and describe operations in Google's vocabulary. There is no stronger branding than your internal philosophy becoming the industry's common language.
The GitLab Handbook works the same way: publishing every operating document established GitLab's reputation as the radically transparent, documentation-driven remote company, attracting remote-minded talent globally. 37signals' Shape Up broadcasts a philosophy of small teams shipping well.
Japanese training releases showcase how well a company educates; overseas knowledge publishing showcases thought leadership.
Education is also a business
The other big difference: overseas, education is not only given away, it is also monetized in an established way. Google's Career Certificates (job training programs in data analytics, cybersecurity, and more) cost about $49 per month through Coursera, and Meta offers certificates in back-end development and other fields the same way.
These programs are designed to be both a talent pipeline that brings newcomers into the industry and a revenue line. Education is treated as a product line in its own right, not a byproduct of recruiting PR. That thoroughness may be the sharpest contrast with Japan's culture of publishing training materials each year as goodwill.
The catch with these materials
The barrier is not only English (or whatever language you read them in). Like the Japanese training materials, most of these assume a working foundation: using a terminal, fetching code with Git, setting up an environment. Without that base, the very first setup step is where things fall apart.
The flip side: with the foundation in place, the barrier drops sharply. Commands and code are universal, so you can follow along from code samples and outputs even when the prose gets dense.
WebTerm Learn is built for exactly that foundation: terminal and Git basics taught through short slides and hands-on exercises, entirely in the browser, in a sandbox you can break and reset instantly. It works well as a runway before diving into these bigger curricula.
Frequently asked questions
Are these big tech learning materials really free? Everything curated in this article is free to read, and many resources, like Microsoft's For Beginners series and Jane Street's OCaml workshop, are published under open source licenses. Career certificate programs from Google and Meta are a different category: they are paid programs delivered through a Coursera subscription, so keep them separate from the free materials.
Do I need to be an experienced engineer to use these materials? Most of them assume you already have a foundation: you can use a terminal, fetch code with Git, and set up a development environment. Beginner-branded curricula like Microsoft's For Beginners series are the most accessible, but even those go smoother once the command line and Git feel comfortable.
How is this different from Japanese companies publishing their training materials? Japanese tech companies hire new graduates in batches and train them together every April, which produces a complete training curriculum that many companies then publish annually. Overseas companies lack that structure, so their education takes different forms: open source curricula, published internal playbooks and handbooks, and ecosystem education platforms for their own technologies.
Next steps
Build the foundation these curricula assume, right in your browser.
- Terminal Introduction: the command line skills every one of these resources takes for granted, hands-on from zero.
- Git Introduction: the tool you need to even download most of these materials, practiced in a sandbox that is safe to break.
Once that base is in place, start with Microsoft's For Beginners series or Atlassian's Git tutorials, and combine them with the Japanese companies' training materials. The amount you can learn for free, across both worlds, is remarkable.
