Blarb

Product Introduction

1. Blarb is a browser-based instant chat platform that enables real-time communication through shareable URLs without requiring user accounts or software installations. Users create chatrooms by modifying any URL (e.g., blarb.net/your-channel-name), with optional peer-to-peer (P2P) encrypted channels for private conversations. The platform automatically deletes message histories after 24 hours in standard channels and offers unlimited participants, embeddable interfaces, and API integration. All interactions occur directly in web browsers, eliminating downloads or platform-specific apps.

2. The core value of Blarb lies in combining instant accessibility with privacy-focused communication through its URL-driven architecture and encryption options. It removes traditional barriers like signups, participant limits, and persistent data storage while providing enterprise-grade features like embeddable chat widgets and REST API endpoints. The service operates entirely free of charge, prioritizing frictionless collaboration without compromising security in both public and private channels.

Main Features

1. Instant URL-Based Channels: Any URL becomes a chatroom by appending text to the base domain (e.g., blarb.net/project-alpha). Channels support letters, numbers, and hyphens, allowing both public (e.g., /general) and private (e.g., /HR-Confidential) naming conventions. P2P encrypted channels are created by prefixing names with @ (e.g., blarb.net/@secure), using WebRTC for direct browser-to-browser communication.

2. End-to-End Encrypted P2P Channels: P2P mode ensures messages never pass through Blarb’s servers, leveraging WebRTC’s SRTP and DTLS protocols for encryption. These channels operate without message persistence, leaving no traces after participants disconnect. The platform automatically negotiates peer connections while maintaining full encryption, suitable for sensitive discussions like legal consultations or medical advice.

3. Automated Message Expiration: Standard channels retain messages for 24 hours before permanent deletion, with no manual cleanup required. P2P channels have zero message storage, ensuring conversations exist only during active sessions. The 24-hour window supports short-term collaboration needs, while the API allows developers to fetch or post messages within this retention period.

Problems Solved

1. Eliminates Account Fatigue: Blarb removes the need for user registrations, passwords, or email verification, addressing the friction of traditional chat platforms. Users join via shared links, making it ideal for one-time events or quick consultations. This approach also reduces phishing risks associated with account-based systems.

2. Serves Diverse User Groups: The platform caters to remote teams needing temporary workspaces, website owners embedding live support chats, and privacy-conscious users requiring encrypted discussions. Developers leverage its API for custom integrations, while educators use it for time-limited class discussions. Healthcare professionals benefit from HIPAA-compliant P2P channels for patient communication.

3. Simplifies Secure Collaboration: Blarb resolves the complexity of setting up encrypted chats by automating P2P connections through URL syntax. Organizations avoid costly enterprise software for short-term projects, and individuals bypass app installations for cross-device compatibility. The 24-hour history feature ensures compliance with data minimization principles.

Unique Advantages

1. No-Account Architecture: Unlike Slack or Discord, Blarb requires no personal information, functioning entirely through URL knowledge. Competitors lack browser-native P2P encryption, while Blarb combines accessibility with security through standardized WebRTC protocols.

2. Dual-Mode Flexibility: The hybrid design supports both server-assisted public channels (with API/push notifications) and pure P2P private channels in one platform. This allows seamless transitions between casual group chats and sensitive 1:1 discussions without switching tools.

3. Cost-Effective Scalability: Unlimited participants in standard channels and free access to all features differentiate Blarb from tiered SaaS models. The platform’s server costs are minimized through P2P data routing and automated message deletion, enabling sustainable free usage.

Frequently Asked Questions (FAQ)

1. How do I create a channel? Append any name to blarb.net/ (e.g., blarb.net/marketing) and share the link—no setup required. For P2P encryption, include an @ symbol (e.g., blarb.net/@private). Channels activate immediately upon first access and support letters, numbers, and hyphens.

2. Are P2P channels truly private? Yes—messages use WebRTC’s end-to-end encryption and never touch Blarb’s servers. Encryption keys are negotiated directly between devices using DTLS and SRTP protocols. Complex channel names (e.g., blarb.net/@9xYq7z) add obscurity against random access.

3. Can I retrieve deleted messages? Standard channel messages are permanently erased after 24 hours, with no recovery option. P2P channels have no storage, so messages disappear when the session ends. The API allows fetching messages only within the 24-hour window for standard channels.
