Rally

Rally is an open-source alternative to Twitter Space/Clubhouse for web3 communities. Built with Polygon, Livekit, Lens Protocol, Lit Protocol, The Graph, Storj, Bundlr and Guild.

Overview

Current social audio apps don't work for web3 communities.

Social audio applications are platforms where users interact with their voice in real time (for instance Spotify Live, Discord Stage, Zoom, Twitter Space...).

Currently, web3 communities rely heavily on those platforms for both their day-to-day communication and important one-time events. The problem: Social audio apps don’t offer the best user experience possible to web3 communities. All current social audio apps lack of one of the following features :

• Access-control flexibility and customization: fine-tuning access to live discussions (for token holders for example) and/or recordings is impossible.
• Accessibility: using a new platform requires to recreate a profile, follow different profiles, join groups, wait to be accepted in the group, follow topics... which is time consuming, and can be a blocker for certain community members, leaving a portion of the community out of the loop
• Discoverability: finding live discussions and/or recordings is difficult.
• Privacy, security and anonymity: current platforms track and sell user data, unbeknownst to said user ; joining live audio as an anonymous user isn't always an option either
• Monetization: platforms don't necessarily offer a way to creators to monetize their recordings/rooms
• Interoperability: announcing live chats and/or sharing recordings hosted on other platforms like Anchor, Apple/Google podcast, Spotify… is impossible, as current platforms try to lock-in users in their platforms. This also means that your content and social graph are tied to the platform - if it goes down, so will your data.

Enters Web3. Web3 is unique because it offers the tools to create an online experience that not only features these 5 principles but also:

• 1️⃣ Easily onboard entire communities;
• 2️⃣ Provides users an online experience where they are in total control of what they publish, who can access it, how, and when ;
• 3️⃣ Provides a permanent and platformless online experience to users, meaning if a certain link in the chain would break, users will still have access to their data and content, regardless of the platform ;

This is why we want to build Rally, the go to social audio app for DAOs and web3 enthusiasts when they want to make announcements, learn, discuss, debate, share, or just chill together.

Rally is a web application at the cross-road of web2 and web3, a social audio platform that will not only allow users to create live audio chats, but also easily onboard entire communities, and provide users a secure online experience where they are in total control of what they publish, who can access it, how, and when.

Deploy to Vercel

Let's deploy the Next.js application to Vercel. If you have ever deployed a Turborepo app there, the steps are quite straightforward. You can also read the official Turborepo guide on deploying to Vercel.

1. Create a new project on Vercel, select the apps/nextjs folder as the root directory and apply the following build settings in Build & Development settings:

Framework preset: Next.js

Build command : cd ../.. && npx turbo run build --filter nextjs
Output directory: Next.js default
Install command: pnpm install
Development command: next

Root directory: apps/nextjs

2. Add your DATABASE_URL environment variable.

3. Done! Your app should successfully deploy. Assign your domain and use that instead of localhost for the url in the Expo app so that your Expo app can communicate with your backend when you are not in development.
