El Foundation

Engineering repository for El Foundation.

About

El Foundation builds institutions that outlast their founders. We create technology and organizations that compound in value over time. This repository is the source of truth for our engineering work.

Getting Started

Read the company charter to understand why we exist.
Read the operating model to understand how decisions are made.
Read CONTRIBUTING.md before making any changes.
Read docs/engineering/local-dev.md for the day-to-day workflow.
Read docs/engineering/hatch-architecture.md for the component map.

Hatch — Deploy in one command

Hatch is a self-hostable HTTP request inspector + mocker. Ship it to any VPS with Docker.

Quick start (local dev, no HTTPS)

docker compose up --build
# Hatch UI: http://localhost:8080
# Health check: http://localhost:8080/healthz

Or run the binary directly:

go run ./cmd/hatch
# Health check: http://localhost:8080/healthz

Production (with HTTPS via Caddy)

# Set your domain name
cp .env.example .env
# Edit HATCH_HOSTNAME in .env to your real domain

# Start Hatch + Caddy (auto-issues Let's Encrypt cert)
docker compose --profile with-caddy up -d --build
# Hatch UI: https://{your-domain}
# Capture endpoint: https://{your-domain}/{endpoint-id}

Architecture

Internet → :443 (Caddy) → hatch:8080 (Go binary, internal network)
                 │
                 ├─ Auto TLS (Let's Encrypt, or self-signed for localhost)
                 ├─ Reverse proxy with security headers
                 └─ JSON access logs to stdout

Caddy terminates TLS and reverse-proxies to the Hatch Go binary. The Hatch container only listens on 127.0.0.1:8080 — it's never directly exposed to the internet.

Technology Stack

See docs/engineering/tech-stack.md for current choices and rationale, and docs/adrs/ for the decision records that produced them.
