Why we built this

Vietnamese devs juggle a dozen separate sites — JSON formatter here, JWT decoder there, regex tester elsewhere — and AI documentation only exists in English or stiff machine-translations. TopDev pulls it all together, in plain Vietnamese.

1
✍️

Browser-only tools

JSON, JWT, regex, SQL, CSS… all 100% client-side. Data never leaves your browser. Works offline.

2
🚀

Fast-moving AI reference

Model launches (Claude, GPT, Gemini) explained within 24-48h. Terms include code examples, not just definitions.

3
🎯

Built for VN devs

VN-specific tools (Gross/Net salary, PIT, loan). Reviews list VND pricing and availability in Vietnam.

Frequently asked questions

What is TopDev?
TopDev is a dev toolbox + AI reference built for Vietnamese developers: 60+ browser-based tools (JSON, JWT, regex, SQL, CSS…), an AI & programming glossary, and honest tool reviews. Hand-written, not machine-translated. Note: TopDev (topdev.com.vn) is a dev toolbox — distinct from topdev.vn, the IT jobs portal.
Is TopDev free?
Yes. All content and tools on topdev.com.vn are completely free. No signup required.
Can I contribute?
Absolutely! Send topic suggestions, fixes, or pitches to hello@topdev.com.vn. Site source is open source on GitLab.
How often is the site updated?
At least 2-3 new terms or 1 new article per week. When a major model launches (Claude, GPT, Gemini), we publish an explainer within 24-48 hours.
Is content AI-generated?
No. All content is hand-written. We may use AI to help with spell-check or structure, but every sentence is reviewed by a human editor.
Do tools send data to a server?
No. All 60+ tools run 100% in your browser — JWT, JSON, regex, SQL, salary, prompt builder. Test it: turn off your network, the tools still work.
