12 repositories for building AI agents that survive contact with a real product
The Agent Library is a free, curated set of 12 public GitHub repositories for building production AI agents, grouped into orchestration frameworks, TypeScript-native tooling, tool and browser integration, and the observability layer you need before launch. Every repository is open source and free to clone. Frenchy Digital adds the part the READMEs leave out: which one to pick, and what breaks when you do.
Free. 12 repositories, no payment. One email address opens the list.
A founder showed me a demo last month that worked. Actually worked. Built over about a weekend, maybe 300 lines, and it did the thing. Then he asked the only question that matters: what do we ship?
Somewhere between that demo and the App Store, the agent needs memory it can trust, a tool call that fails politely, a trace you can read at two in the morning, and a bill that doesn't quietly triple. None of that is in the tutorial he followed.
Here is the part most people get backwards. They think the bottleneck is picking the right framework, so they spend three weeks comparing them. It almost never is. The bottleneck is the boring layer underneath: what you log, what you test, what happens on the fourth retry. Teams that pick a framework in an afternoon and spend the saved fortnight on tracing ship sooner, roughly every time.
So one rule before you start clicking: choose a single orchestration framework and stay there for a month. Framework-hopping is the most expensive habit in this field right now. Every switch costs you the thing you were actually building, and they are converging anyway. The differences that look enormous in a comparison table mostly vanish once you have real users and real failure modes.
This is the list we hand clients. Twelve repositories, all public, none of them ours, which is the point. We've shipped on most of these and walked away from a couple, and the notes say which and why. That judgement is the only thing here you can't get off GitHub's trending page.
It's free. There's a tip bar further down where you type whatever amount you think it was worth, because a few people asked for one, but nothing is behind it. Same list either way.
Where to send the 12 repositories
Give me an email address and the full list opens on this page straight away, with a copy in your inbox you can search later, plus a note whenever we publish something new on AI and where mobile development is going. No payment, now or ever. That's the only trade.
Orchestration: where the agent actually lives
Pick one. Picking two is how projects die. These are the four we have shipped against, and the honest reason you would choose each.
6 repositories, with the notes on each. Enter your email above to read them.
If your product is TypeScript, start here
Most agent tutorials assume Python. Most mobile and web products do not. These two close that gap.
2 repositories, with the notes on each. Enter your email above to read them.
Tools: the part that makes an agent useful
A model with no hands is a chatbot. This is how you give it hands, and how you keep the connection standard instead of bespoke.
2 repositories, with the notes on each. Enter your email above to read them.
Production: the boring half nobody posts about
The demo is the easy 20%. These two are what stand between a working prototype and something you would let a client near.

The master list: all 100 repositories
The free list above is the short version, and every repository on it is in here too. The Gods Repo Library is the whole catalogue: 100 repositories across 12 categories, each with a written note on what it is for and when to reach for it, and it carries the AI optimisation half, inference, serving, quantisation and evaluation, that the free list barely touches. Every figure in it is read from the GitHub API rather than typed by hand, and nothing archived or idle survives the build. Verified 2026-09-23.

Before you buy, the terms of this sale
- The full catalogue is delivered to the email address I give, immediately, the moment my payment clears.
- Because it is delivered in full straight away, all sales are final: no refunds, no partial refunds, no exceptions, for any reason.
- I am asking for that immediate delivery and I give up any cancellation or cooling-off period that would otherwise apply to digital content.
- If the email does not reach me, Frenchy Digital will re-send it to my address for as long as I need, and that re-send is the remedy rather than a refund.
- The repositories listed are third-party open-source projects. Their availability and their licences are theirs to change, and I will check any licence myself before using it commercially.
The same terms are in full in our terms and conditions, and you will be asked to accept them once more on the Stripe payment page.
You can change the address at checkout, and that is where it is delivered. Secure checkout by Stripe, and we never see your card.
Tip if it helped. Only if it helped.
The library costs nothing and stays that way. You already have it, whether or not you type anything here. If it saved you an afternoon, name your own amount. It goes toward the time we spend testing these so you don't have to.
Anything from $2. You can still change it on the next screen. Secure checkout by Stripe, and we never see your card.
