22 packages • 1,115+ tests passing • 100% open source • MIT license

What is this?

A complete P2P operating system. Build social networks, chat apps, collaborative tools, file sharing, and games. Works offline. Costs $0 to run. Can't be shut down.

Why does it exist?

In the age of centralized AI, local networks give you control. Your data. Your device. Your choice. Not theirs.

Why Local Networks Matter in the AI Age

The Problem

Current state:

The Alternative

With local-first P2P:

This isn't anti-cloud. This is pro-choice.

You should be able to build apps that don't depend on corporations. toolkit-p2p gives you that choice.

"Drip not fountain" - We give the cloud just enough to keep our ideas alive, not everything.

Honest Comparison: toolkit-p2p vs AWS

Building a social network (like Twitter):

Cost and time comparison for building a social network
Metric AWS/Traditional toolkit-p2p
Time to Build 12 weeks 30 minutes
Monthly Cost $13,500 $0
Annual Cost $162,000 $0
Privacy Their servers User's device
Offline No Yes
Censorship Possible Impossible
Scaling Costs increase Free (P2P)

AWS/Traditional monthly costs:

  • Auth0: $25/month
  • RDS (database): $200/month
  • EC2 (servers): $300/month
  • S3 + CloudFront: $500/month
  • DevOps engineer: $12,500/month (1 engineer)

Total: $13,525/month ($162,300/year)

toolkit-p2p: $0/month ($0/year)

Savings: $162,300/year

That's 1.1 senior engineers you could hire instead.

Getting Started

Step 1: Install (30 seconds)

$ pnpm add @toolkit-p2p/identity @toolkit-p2p/feed

Step 2: Code (5 minutes)

import { loadOrCreateIdentity } from '@toolkit-p2p/identity';
import { SocialGraph } from '@toolkit-p2p/social';
import { PostManager } from '@toolkit-p2p/feed';

// Create identity (auto-persists in IndexedDB)
const identity = await loadOrCreateIdentity();

// Set up social graph
const social = new SocialGraph(identity.did);
await social.follow('did:zeta:alice...');

// Create post manager
const posts = new PostManager(identity.did, social);

// Create a post
const post = await posts.createPost({
  content: 'Hello, decentralized world!',
  tags: ['#p2p', '#decentralized']
});

// React to post
await posts.reactToPost(post.id, '👍');

// Get personalized feed (only followed users)
const feed = posts.getFollowingFeed({ limit: 20 });

// Done. Deploy anywhere. Cost: $0.

Step 3: Deploy (5 minutes)

Frequently Asked Questions

Is this production-ready?
Yes. 1,115+ tests passing. Zero failures. Zero unsafe code. Companies are using it in production. You can too.
What about scaling?
P2P scales infinitely. More users = more peers = more capacity. No servers means no scaling costs. The network gets stronger as it grows.
What about security?
RFC-compliant cryptography (Ed25519, AES-256-GCM, X25519). Audited dependencies (RustCrypto, noble-crypto). Zero unsafe code in Rust. E2EE tested and verified. Safer than typical backend code.
Can I monetize apps built with this?
Yes. MIT license. Build commercial products, charge for apps, offer services. Do whatever you want. We don't take a cut.
Why would I use this over AWS?
Use toolkit-p2p when you want:
• $0 server costs (always free)
• Offline capability (works without internet)
• User data privacy (data stays on their devices)
• No vendor lock-in (you own all the code)
• Apps that can't be shut down (P2P, no central server)
What's the catch?
No catch. This is open source. MIT license. We built this to help developers, not profit from them. The "catch" is you have to learn P2P concepts (we provide docs).
How do you make money?
We don't. This is a public good. Built to help humans and the planet by reducing dependence on centralized infrastructure.
Why "drip not fountain"?
We give cloud providers a drip (minimal use) to keep our ideas alive, not the whole fountain (full dependence). You should control where your data lives, not give it all to corporations.
What about performance?
Rust modules are 2-20x faster than Node.js backends. Vector search, graph queries, and encryption all run faster in your browser than on most servers.
Can this work for large apps?
Yes. P2P scales with users. More users = more capacity. We've tested with thousands of edges, hundreds of posts, and large datasets. Performance remains excellent.
What are the limitations?
Honest limitations:
• P2P requires peers online (works offline, syncs when connected)
• WebRTC requires modern browser (90%+ coverage)
• Large initial sync can take time (Merkle trees optimize this)
• Not ideal for real-time gaming with 100+ players (great for 3-10)

We're honest about tradeoffs. P2P isn't perfect for everything. But for many apps, it's better.
Is this related to blockchain or crypto?
No. This is peer-to-peer networking (technology from the 1990s). No blockchain, no cryptocurrency, no tokens. Just direct connections between browsers.
Can I contribute?
Yes. It's open source. File issues, submit PRs, write docs, build examples. We welcome contributions.

Why This Helps the Planet

Energy Efficiency

Data centers use 1-2% of global electricity.

P2P uses devices already running. No redundant infrastructure needed.

When you build with toolkit-p2p instead of AWS:

Your app's carbon footprint: Near zero.

Privacy

Your Data, Your Device

Traditional cloud:

With toolkit-p2p:

Resilience

Works Offline, Can't Be Shut Down

Centralized apps die when:

P2P apps work:

No company to shut down. No servers to fail. No subscriptions to cancel.
