Frequently asked questions
What is The Big Learn?
The Big Learn (TBL) is a free learning platform for developers. Its core is an in-depth, multilingual track on corporate APIs — networking, security, protocols and architecture — supported by practical articles.
What does "Explore more. Understand deeply." mean?
It is the promise of TBL: keep exploring new topics, and go deep enough to truly understand how things work — not just memorise them.
Is everything really free?
Yes. All learning content and articles are completely free, require no account and open directly in your browser.
Which languages are supported?
The Learn track is available in English, Portuguese and Spanish, with the same 40+ chapters in each language.
Who is The Big Learn for?
For developers, architects, students and anyone who works with or wants to understand corporate APIs — from people taking their first steps to experienced engineers filling gaps in networking, security or architecture.
Do I need to follow the chapters in order?
No. The Learn track is designed as a progressive series, so reading in order builds the strongest foundation, but every chapter also works as a standalone reference you can jump straight into.
Do you use cookies or track me?
We do not store cookies on your device. Reading progress is kept locally in your own browser, and for security we retain only the request IP and accessed path for 7 days. See the About page for the full cookie and privacy policies.
Are there developer tools here too?
Yes. Alongside the learning content, The Big Learn includes a set of free, no-sign-up developer utilities — Base64, JSON, JWT, QR codes and more — available under Tools.
