Let's talk

Whether you have a tool idea, found a bug, want to collaborate, or just want to say hello — I genuinely read every message and reply personally.

HeoLab is a solo project. Your feedback directly shapes what gets built next.

No newsletters, no spam. Just a real reply.

Other ways to reach me

GitHub

@NgoTTrong

Open a discussion or issue — bugs and feature requests are best tracked here.

Email

trongngo08082002@gmail.com

For partnerships, private inquiries, or anything you'd rather not post publicly.

Response time

Usually within 1–2 days. GitHub issues get the fastest turnaround since they're tracked publicly.

Suggest a tool

The roadmap is entirely driven by what developers actually need. If there's a tool you reach for every day, I want to build it.

Frequently asked questions

How quickly do you respond?

Usually within 1–2 business days. GitHub issues tend to get the fastest response since they're tracked and public.

Can I request a specific tool?

Absolutely — tool requests are the most valuable thing you can send. Describe your use case and I'll add it to the roadmap. The more detail the better.

What kinds of feedback are most helpful?

Anything specific is gold: a workflow you wish HeoLab could handle, an edge case that broke a tool, a feature that would save you time every day. Real-world use cases drive everything.

Can I contribute to HeoLab?

The codebase isn't open-source yet, but ideas, feedback, and bug reports are genuinely valued. If you want to get more involved, just reach out.
