spasteg

A secure, self-hostable "burn after reading" paste service with ephemeral storage written in Gleam.

Features

• Ephemeral pastes — Content is deleted immediately after first view
• No persistence — All data stored in-memory only (restarts clear everything)
• No accounts — Zero-friction sharing without registration
• Self-hosted — Run your own instance with full control
• Fast & lightweight — Built on the BEAM VM for reliability and performance
• Type-safe — Written in Gleam, a type-safe functional language

Quick Start

# Clone and build
git clone https://git.kharec.info/Kharec/spasteg.git
cd spasteg
gleam run

The server starts on http://localhost:3000.

Usage

1. Visit http://localhost:3000
2. Enter your text in the form
3. Click "Create Paste"
4. Share the generated URL
5. The paste auto-destructs after first access

Architecture

• Web framework: Wisp (Gleam's web framework)
• HTTP server: Mist (HTTP/1.1 & HTTP/2)
• HTML rendering: Lustre (type-safe, declarative HTML generation)
• Storage: In-memory OTP actor (no disk persistence)
• Key generation: Cryptographically random 16-character keys

Security Notes

• Pastes are stored unencrypted in server memory
• Data is never written to disk
• All data is lost on server restart
• Intended for ephemeral sharing only — do not store sensitive data
