Learn & build working systems
Structured engineering guides on AI Agent loops, n8n error handling, and production cloud deployments.
Your First LLM API Call: Messages, Tokens and Limits
Make one model call from Node.js with any provider and understand every part of it: the messages list, the system prompt, tokens, output limits and why answers vary.
Get JSON You Can Trust from an LLM (with Zod Validation)
Ask a model for JSON, validate it with a Zod schema, and retry once with the error message, so your code only ever sees data with the right shape.
Agent Guardrails: Step Limits, Timeouts, Cost Caps and Human Approval
Add the four limits every agent needs before it touches real systems: a step budget, per-call timeouts, a token/cost cap, and a human approval gate for risky tools.

Frequently asked questions
Is DevHubTools free?
Yes. The browser tools, workflows and lessons are free. A few starter kits and bundles may be paid, and their pages show the price.
Do the free tools upload what I paste?
No. The tools run in your browser, so the text you paste stays on your device.
Do I need an account?
No. You can use the site without signing up. An optional free account saves your lesson progress and bookmarks.
How are the AI tools reviewed?
Each review is based on the tool's official site, pricing page and docs, and shows the date we checked. A review says "Tested by us" only after we have used the tool ourselves.
Do you earn money from links?
Some links are partner (affiliate) links and are marked as such. If you buy through one, we may earn a commission at no extra cost to you.
How often is something new added?
New tools, guides and workflows go live every week. The tools coming next are listed on this page.
