Self-hosting LibreChat: one ChatGPT UI for your whole team, billed per token instead of per seat

Description and use

Self‑hosting LibreChat lets teams use a ChatGPT‑style UI with per‑token billing, cutting costs from ~$100 to ~$10–30/month while ensuring security and persistent context.

Problem

Teams face high per-seat costs with ChatGPT Plus while needing a shared, cost‑effective AI interface.

Outcome

Teams can reduce AI costs from ~$100/month to ~$10–30/month while maintaining shared context and security.

Workflow

• Clone LibreChat repo
• Copy .env.example to .env
• Generate real JWT secrets with openssl rand -hex 32
• Set API keys for at least one provider in .env
• Run docker compose up -d
• Open port 3080 and register first admin account
• Disable open registration in settings
• Set spending caps on each provider dashboard
• Restart stack and verify chat history persistence
• Schedule regular MongoDB backups

Evidence

LibreChat is the open‑source ChatGPT‑style interface that turns that per‑seat subscription into a per‑token API bill.

Source

MongoDB holds accounts and conversation history. That is where your team's accumulated context lives, and it is the thing you can lose.
