Vibe Coding for Localization with Crowdin

Everyone Is a Builder Now

Something quietly broke open in the language industry.

Since ChatGPT landed in late 2022, and even more so since AI coding assistants like GitHub Copilot, Cursor, and Claude Code went mainstream, the wall between linguists and developers has thinned to almost nothing. GitHub reports that more than 1.8 million developers paid for Copilot Business or Enterprise as of early 2024, and Stack Overflow finds that over 76% of developers are now using or planning to use AI tools in their workflow.

What used to require a software engineer can now start with a prompt and a willingness to iterate.

One Hour, One Capability, Inside Crowdin

This session does not talk about vibe coding in the abstract. We pick Crowdin, a market leading translation management platform trusted by Microsoft, GitHub, GitLab, Bolt, and thousands of others, and we build a new capability into it live, on screen, in under sixty minutes.

As Andrej Karpathy put it when he coined vibe coding in 2025, you stop thinking like a programmer and start thinking like a product owner.

For localization, that means small, useful extensions to the tools you already pay for are now within reach of anyone fluent in the workflow.

You walk away with the spec, the prompts, and the repository for the capability we build together, plus a clear sense of what you could build into your own Crowdin setup.

Vibe Coding for Localization, Live with Crowdin

Watch a localization pro vibe code a new capability into Crowdin in 1 hour.
Learn the prompts, patterns, and guardrails to do it yourself.

Vibe Coding
for Localization

Module 1

1.1 Vibe coding in 5 minutes: from prompt to working software
1.2 Crowdin as a platform: apps, webhooks, AI providers, API, and where extensions plug in
1.3 Today's spec: the capability we are going to build and why it matters
1.4 Live build, part 1: spec first prompting and the first working version
1.5 Live build, part 2: iteration, debugging, and wiring it into Crowdin
1.6 What stays human: review, security, and where to stop
1.7 Live Q and A, repo handover, and what to build next

Course Description

In one focused hour, we go from blank screen to a new capability running inside Crowdin.

The capability we pick is small enough to be built live, but real enough to matter: an AI assisted addition to the Crowdin workflow that you could keep using after the session ends. Along the way, you see exactly how vibe coding works in practice, prompt by prompt, decision by decision.

Specifically, you leave able to:
  • Describe what vibe coding is and how it differs from traditional development.
  • Recognize where Crowdin can be extended (apps, webhooks, AI providers, the API) and which extension point fits which problem.
  • Follow a spec first prompting flow that turns a fuzzy idea into working code without writing the code yourself.
  • Spot the moments where the AI assistant tries to bluff, and know how to push back.
  • Decide whether the capability you have in mind is a one hour vibe coding job, a one week project, or a real engineering build.

Who Is This Course For?

This session is built for localization professionals who want to stop waiting for someone else to build the tools they need.

It is ideal for:
  • Crowdin users on the buy side who keep running into the same gap in their setup and want to know if it can be filled without a six month integration project.
  • Localization project managers who want to see, end to end, how a working capability gets built so they can scope similar work realistically.
  • LSP operations and innovation leads exploring how AI assisted development lowers the cost of internal tooling around TMS platforms.
  • Freelance translators and senior linguists who would happily use a smarter Crowdin if someone showed them how to extend it themselves.
  • Localization engineers who already code and want to see a focused vibe coding workflow they can compare to their own.
  • Curious non technical localization professionals who suspect this whole AI coding thing applies to them and want a safe place to watch it happen.

No prior programming experience is assumed. If you can describe a Crowdin workflow clearly in writing, you have what it takes to follow this session.

Resources

This is a live session you can follow as a watcher, no setup required.

If you want to follow along and build the same capability later, please come prepared with:
  • A free Crowdin account. The free plan is enough to follow along.
  • Optional: a sandbox Crowdin project with a small bilingual file, so you can try the capability against your own data afterwards.
  • A free GitHub account, used during the live build to host the resulting code.
  • Access to at least one AI coding assistant. Options shown during the session include GitHub Copilot, Cursor, and Claude Code. Any one of these is enough.
  • A code editor (VS Code or Cursor, both free) installed if you plan to reproduce the build later.
  • English at a B2 level or higher, since both the session and the AI tools are English first.

Reminder: building anything on top of a paid platform like Crowdin is your responsibility regarding terms of service, data handling, and security. We cover this explicitly in the session.
