Tips for improving mini app UX
Optimize your Farcaster mini apps for mobile
The best mini app builders optimize for building on mobile. A few general tips for making best-in-class mobile mini apps:
Simplify screens
Make buttons and touch targets bigger
Remove unnecessary crypto jargon and UI complexity
Example: Crowfund mini app

Here's an example on how to improve a popular mini app, Crowdfund.
Consider moving anything optional to after you complete the primary action, so in this case the comment would come after the donation
Make the primary action -- adding a donation amount -- bigger and place it front and center
USDC + logo, the wallet selected are not useful for 95% of people
The available balance is useful, so consider making that a clear secondary piece of info
Make the primary button big and easy to tap on a mobile device.

Build Farcaster mini apps with AI
llms-full.txt makes it easy to use LLMs to build mini apps
If you're developing Farcaster Mini Apps and want them to integrate seamlessly with large language models (LLMs) like ChatGPT, there's now a purpose-built tool for you:
https://miniapps.farcaster.xyz/llms-full.txt
This file distills the entire Farcaster Mini App documentation—including setup, SDK usage, embeds, manifests, wallet support, and more—into a single LLM-ingestible format. It enables:
Full-context RAG workflows with any GPT-style model
Offline use with tools like Cursor or local models
Custom AI assistants trained on Farcaster Mini App dev knowledge
Fast onboarding for new developers using ChatGPT or Claude
Unlike sprawling web docs, llms-full.txt
is structured for language models:
no layout noise, just dense, useful text formatted for parsing.
How to Use It
Copy or curl it into your local AI tooling
Link it in your own docsets, devtools, or GitHub repos
Prompt AI agents with: "You have the full Farcaster Mini App documentation in context..."

Improved Dev Tools
Better tools and analytics for mini app developers
The new tools are focused on validating, previewing and publishing mini apps.
We removed building the JSON builder since starter projects and other tools can help with that (more to come) and removed localhost support because it didn't work well and it was a source of frustration for devs, we recommend using a tunnel instead.
We also now provide developers with analytics for mini apps. Developers can now see how many unique users, opens, transactions and unique users with a transaction their mini apps have.
You can access the new dev tools here.

Snapchain is now live
Faster and more reliable infrastructure for Farcaster
After 8 months of work, Farcaster is now running on Snapchain.
Warpcast and Neynar are reading and writing from Snapchain. Casting across apps is now faster, more reliable and more likely to scale as Farcaster grows.
Here's a video to explaining how it works:
Snapchain unlocks many new improvements:
Cheaper storage — we should be able to reduce the cost of storage by 10x today and even more over time as we make improvements.
Zero cost signers — moving signers to Snapchain means users can add and remove apps for free.
App based storage — Make it easier for apps to sponsor users and enable "free onboarding" for the majority of users who want to join Farcaster
