Mini-apps are mini for a reason - keep them simple, snappy, and fun. You don’t need a full-fledged product, just something people can interact with instantly. The magic comes from social dynamics, not complexity.
Here’s what makes a mini-app go viral in the Farcaster ecosystem:
You’re building inside a social network - don’t waste that context.
Use the Farcaster social graph to pre-fill friends and connections.
Pull in usernames, avatars, and bios from their FC profiles.
Add leaderboards, badges, and stats - competition fuels engagement.
Show activity feeds: “your friends just did X.”
Think multiplayer, even for solo experiences - show people with people.
Make it effortless and fun for users to cast what’s happening.
Add a “Share to Warpcast” button at key moments.
Auto-compose the cast text with fun copy + a link to your mini-app.
Avoid auto-tagging users in prefilled text – it might feel spammy and could discourage organic sharing.
Embed the mini-app URL in the cast.
Use Open Graph tags to generate a custom preview image for the embed.
💡 Bonus: Customize the image with dynamic data (e.g., “Castled with 4 friends” or “@alice scored 91 points”).
Your mini-app should look good in the feed - that’s where new users will discover it.
Make the preview image eye-catching and legible in small format.
Include social proof directly in the preview (e.g., avatars of active users, usage stats).
Make it easy to jump in.
Users opens your app and are automatically signed in
Support deep linking with context (e.g., invite URLs, challenge links).
Let users bring friends - share links that invite them into a specific room, game, or session.
Autofill names and avatars from Farcaster so onboarding feels instant.
Check out Warpcast Intents URL for more about deep linking.
People love to flex. People love dopamine.
Highlight who did what inside the app (recent activity, “top player,” etc).
Let people earn or collect things while using it — a badge, an early access.
Show who brought in new users. Referral vibes, but social.
Reward people for casting your mini-app. Should be easy to figure this out with protocol data and URL parsing.
Interact → get feedback → share → bring others in → repeat.
If someone uses your app and no one else knows, you failed.
Think of every click as a chance to trigger the next user.
Farcaster lets you reach users where they already hang out: their Warpcast notification inbox.
Leverage this natively social push channel to re-engage and spark action:
Send to all your followers (or specific frames/mini-app users).
Use for:
New features or challenges (“New quiz just dropped!”)
Time-limited events (“You have 2 hours to vote!”)
Community milestones (“1,000 players joined today!”)
Trigger notifications based on user actions or app events:
“You lost your top spot on the leaderboard. Come take it back 👀”
“@dave just replied to your poll.”
“Your daily reward is ready.”
Notify when friends interact with your cast or mini-app:
“@alice joined your room.”
“3 of your followers also played today.”
🔁 This helps build habit loops: users leave, but your app nudges them back.
Important
The best practice is to trigger the "Add Frame" action (and enabling notifications) as soon as the mini-app loads - this is common behavior in most popular mobile apps. However, some users may find this approach too aggressive. They might prefer to explore the app first and then decide to add the frame and enable notifications.
Be mindful not to spam. Use notifications thoughtfully - to deliver real value, spark curiosity, or tap into social FOMO.
The launch phase can make or break virality.
Add a referral or pre-save system before going live - it helps build early momentum and gives you a solid user base to notify when you launch.
Reward early signups with perks, badges, or access (e.g. waitlist access)
Use Warpcast notifications to bring pre-savers back when the app is live.
Consider launching with a challenge or leaderboard to fuel early engagement.

Really enjoying the new Feuds on Farville. It gives me an excuse to open the mini app more even when I have no “gameplay” for myself for 12-15 hours. This is how you hook people on your app: - Remind me to take action, often ans when I have a task to do - Make it social - Let me play as a team and not just PVP
@linda not sure if you all keep a list of mini app best practices but whatever the Farville team is doing should go on them. It keeps me engaged without being annoying. That’s a crucial balance and they and they are threading the needle well!
I share this with builders all the time! https://paragraph.com/@builders-garden/viral-farcaster-mini-apps
So great! I’ll encourage them to update with the new mechanics. The game is getting even stickier. I’m no longer playing for me. I have a team relying on me and we all do well together. Co-op farming has a new meaning!
Yayyy hadn’t started using it yet cause didn’t know which to join haha Just sent a request
Added you! Let’s Farm!
Asked to join! 🤩
Added you!
really happy to read this pichi <333 the cool thing is that Feuds just started and cool stuff is coming VERY soon :)
Omg me too 🥰
Some thoughts on mini app go to market (not comprehensive): - get users to give feedback and test early before launch. They'll likely want to help support when it launches too (ping me if you want to join a group chat of 300 mini app testers) - don't mass spam when reaching out to people in DCs, be thoughtful - @ampsfun is a great tool for getting more distribution - use notifications to help with retention and keep users updated about new rewards, challenges, etc - @qrcoindotfun gave a small amount of tokens to anyone who added mini app -> one of the most popular right now in terms of opens. Also QR is great for getting distribution - founders and community members can tip tokens through @noiceapp for distribution - add social features where users keep coming back or compete e.g. MiniWord by @cbeav, FarGuesser by @vmathur - add a share on Farcaster button in mini app, bonus if it can be a personalized image for the user so they're more likely to share (a lot of builders forget to add this)
I also constantly share this post by @limone.eth who built /farville to builders on how to go viral https://paragraph.com/@builders-garden/viral-farcaster-mini-apps
Followed this to the dot and it has great insights! Thanks @limone.eth
I'd love to join the group of 300 pls tysm

last week i reviewed ~20 /miniapps from folks asking how to go viral. most were missing two key things: sharable moments — prompt users to share any fun/relevant action (mint, score, goal hit, etc). this drives discovery. social data — i'm here to connect, not go solo. zynga poker didn’t win on poker UX, it won on poker with friends. add these, and you’re already 10x ahead.

read this @cbeav
got any guides on how to build simple mini-apps? trying to make one with the help of chatgpt but some more guidance would be great (it's telling me to use react + vercel, no idea if that's the way to go)
next.js + vercel is your way to go get started: https://miniapps.farcaster.xyz/docs/getting-started next.js starter template: https://github.com/builders-garden/farcaster-miniapp-starter @samuellhuber.eth do you have any step by step guide that could be useful here?
day 3 with mustaches: i feel 14% wiser and 37% more italian.
building something that encourages meaningful connections within a community >>>
@cbeav follow mini app thought leader @limone.eth know there's lots of lower hanging fruit but mutuals leaderboard w/ custom brag that tags mutual above and below (I beat X, Y beat me) would go hard
100%
These are fantastic ideas. Will see what I can do
gonna keep adding your wisdom to the walkntalk feed https://walkntalk.tv
tks, i forgot lol!
love the mou
i’m close to @macedo’s look
haha
mou competition ? is there a mini app for that ?
those sunglasses 😍
vamp
love the shades
still always shook seeing you without the hat 😂
@payton i think you started a trend ngl
I gave the mustache a chance too 👀 @payton has really launched a new trend among us
pic or didnt happen
Ahahaha let’s goooooo! I am honored. You all better be ready for the photo op in October 🥸
a 40 minutes workshop on how to build mini apps on Farcaster thanks again /monad and @linda for inviting me!
I'm not a developer but I like Farcaster. Do you think I could make a mini app as someone who knows nothing about programming? Is it worth a try?
yes vibecoding is real try @ohara-ai or @farcade studio!
I will look into it and try it out with my teammate. Thx for information👌
want your mini app to go viral? drop your link below — i'll give you actionable feedback and tips to boost growth, virality, and retention let’s make it pop 🫡
prefer doing solo? i got you https://paragraph.com/@builders-garden/viral-farcaster-mini-apps
I would love to learn how to build a good mini app
try to be more specific, what's the hardest part for you right now? how can i help?
gonna drop something here once i get some time to polish my mini apps!! great opportunity for mini app devs 🙌
sure, here to help!
i have a mini app for audio spaces: https://spaces.0xmoe.com/
- main preview image should show some currently live spaces (with user pfps involved) - spaces list should include info about the creator (pfp, username..) and info about current users attending (pfps, "x,y,z and 5 more are listening...") - when sharing a space, the preview image should include social proofs (who created it, who's attending...)
- notification when somebody i follow creates a space - notification when sombody i follow joins a space
https://memories.nexth.dev/
mmm there's not much i can say here, is a cool one shot experience, well designed - i would make the "share" button more prominent, as the main CTA of the app - i would allow users to mint their top memory for $1 - it would be cool to navigate memories from people i follow as well - the main preview image is not clear, i would showcase an example top cast and make it more clear that memories are your top performing cast ever i guess?
Good feedback, thanks 🙏
Its still WIP, but your OG thoughts are always welcome! https://warpcast.com/miniapps/X_DQ70cYHoX0/product-clank
- "believe" and "believe buy" disoriented me, i would highlight more the "Believe buy" (not sure where my USDC are going to? is it like a tip? - on product detail page, show me who believed / believed buy in a project - on product detail page i'm missing a share button that goes to the feed, and shows project creator, title, logo, number of believers and their pfps - after believe / believe buying, prompt me to share that i "believed" on the feed, with a custom preview image for the project (title, logo...) and cast saying that i believed in that project - on leaderboard, show on top my leaderboard position, add a share button to share my position in the leaderboard - make the daily points streak more highlighted, you can add it top right corner of the app - i'm missing how i can create a new project
- notification when somebody i follow creates a new project - notification when somebody believes in my project - notification when my projects gets believed 10,50,100 times
Awesome stuff Limone! I might drive up to Lisbon to come and hug you ( Or u are invited for a pool party in the algarve if u want ;-)
https://fundraiser.farcastle.net/
- main page should show active campaign list, and a create campaign button - campaigns list items should include: fc creator pfp and username, fc data from people who contributed - campaign detail page should have a secondary button "share" below "contribute to campaign" (not just - contributing to campaign should be possible with multiple tokens (then could still resolve in ETH if you prefer) - the share campaign preview image is not loading for me, similarly to @crowdfund i'd include campaign title, pfps of who contributed and amount contributed so far vs. target goal - make it so when sharing it's not a long cast, impersonating the campaign creator, but something simpler like "i supported @<user>'s <campaign name>..."
Grazie
@crowdfund
the app is ✨ the only thing i'd change from the in-app experience is using @daimo-pay to allow users paying with any token main issue i have is around credibility of the campaign creator, seeing who contributed and how much is great, i think you can also show me stats like how many mutuals i have with the creator not sure about notifications, these two are top of my mind rn - notification when a campaign i supported gets fulfilled - notification when somebody donates to my campaign maybe reward me with some "points" if i share a campaign on the feed and somebody ends up donating through my referral? what if the main url preview image shows active campaign preview instead of just the static app name and logo?
100%! @nicholas boost your crowdfunds by accepting any token on any chain, without changing a single part of your backend. Just plug our SDK on top of your UI. Happy to help get you onboarded!
https://wtw.degenapp.store/wtw
- post author should include farcaster pfp and username, not just an address - shared preview image should include pfps and amount of users who are using the app - after creating a post, prompt me to share on the feed, with a custom preview image showing my profile data, and the text i shared (include here also total people using the app - social proofs are key!) - notify me when a user i follow on farcaster posts something on the mini app in general i feel like it's not benefiting at all from the farcaster social graph, include more data, show me what people i follow are posting etc.
Thank you 🙏. It's all valid points. Will fix one by one.
hey @limone.eth any chance we can get your slides from the farcon conference?? Lots of great tidbits I would love to share with some people im tinkering with

Such a great read. I try hard this days to create a miniapp (they Ideas are dead in my brainland) :))
I like this!! Some solid tips!
great read!
Best of luck

a guide on how to build viral mini-apps on farcaster 👀 less about complexity, more about tight loops, social moments, and dopamine triggers sharing what we learned from building /farville, /betttr, and helping other teams ship during /just-frame-it (also: if you need help building yours, dm's open 🫡)
300 $DEGEN
Have to read this💆🏻♂️🖤
excited to dig in!
amazing article. the viral loop is such a key component of it cc @farcasteradmin.eth what are your core takeaways for building sucessful mini apps so far?
1. simplicity 2. incentives 3. if people don't share a mini app DAILY, it will die 4. token is a must
agree on all, except for 4. /farville is been among the trending frames since january without a token this is why we didn't launch it https://warpcast.com/limone.eth/0xa7615b3f ofc we're working on more onchain stuff - but not on an erc20 token
Awesome, a must read for all builders 👏
ets gooo
really nice !! looking at your git to see see if i can fiure out why my mini app is going past the splash screen on desktop but not on mobile ...
have a look at frames-v2.builders.garden, there's a bunch of starters
yep , that what i started to look at
@sausagedad check this
GM TO my meow @casterchain.eth @casteragents
how could u make us go viral hot.cast.money
really cool, i see u use social proofs already, are there any sharable features / moments? first time for me seeing your frame, never noticed in the frame also, what notifications are you sending?
currently, what users share are OG's when they make a txn: the price they bought, how much they bought it for etc notifs: when tokens hit 10k vol by min 10 fc users in 15 minutes, or 30k vol by min 20 fc users in 30 mins that's all no social graph based notifs yet
GM TO my meow @casterchain.eth @casteragents

Thanks for this , shared to my community 🙏🙏
