Chalk is a self-hosted, open-source alternative that gives you the same capabilities — SIS sync, SAML SSO, vendor data feeds — without the recurring costs. You own your data, control your infrastructure, and avoid vendor lock-in. Chalk works with PowerSchool, Infinite Campus, Skyward, and any SIS that supports OneRoster CSV or API exports.\n\n## Features\n\n- **SIS Connectors** — PowerSchool, Infinite Campus, Skyward\n- **Identity Provider** — SAML 2.0 SSO with QR badge and picture password login\n- **Google Workspace Sync** — Automated user provisioning and OU management\n- **OneRoster 1.1** — CSV import/export and REST API\n- **Clever-Compatible SSO** — Drop-in Clever API replacement for seamless vendor migration\n- **ClassLink-Compatible SSO** — Drop-in ClassLink API replacement\n- **Active Directory Sync** — Automated AD user provisioning via LDAP\n- **Migration Tools** — Switch from Clever or ClassLink with guided migration\n- **Admin Console** — HTMX-powered web UI with dashboard, user directory, and settings\n- **Security** — Session auth, CSRF protection, AES-256-GCM encryption at rest, audit logging\n\n## Requirements\n\n- **Operating System** — Linux or macOS (Windows supported for development)\n- **SQLite** — Version 3.35 or later\n- **Network Access** — Connectivity to your SIS instance (PowerSchool, Infinite Campus, or Skyward)\n\n## Install\n\nDownload the latest binary for your platform:\n\n| Platform | Download |\n|----------|----------|\n| Linux (x86_64) | [chalk-x86_64-unknown-linux-gnu](https://github.com/usechalk/chalk/releases/latest/download/chalk-x86_64-unknown-linux-gnu) |\n| macOS (Apple Silicon) | [chalk-aarch64-apple-darwin](https://github.com/usechalk/chalk/releases/latest/download/chalk-aarch64-apple-darwin) |\n| macOS (Intel) | [chalk-x86_64-apple-darwin](https://github.com/usechalk/chalk/releases/latest/download/chalk-x86_64-apple-darwin) |\n| Windows (x86_64) | [chalk-x86_64-pc-windows-msvc.exe](https://github.com/usechalk/chalk/releases/latest/download/chalk-x86_64-pc-windows-msvc.exe) |\n\n**Linux / macOS one-liner:**\n\n```bash\ncurl -fsSL https://github.com/usechalk/chalk/releases/latest/download/chalk-$(uname -m)-$(case \"$(uname -s)\" in Linux*) echo unknown-linux-gnu;; Darwin*) echo apple-darwin;; esac) -o chalk \u0026\u0026 chmod +x chalk \u0026\u0026 sudo mv chalk /usr/local/bin/\n```\n\nAfter installing, run `chalk update` to stay current with future releases.\n\n## Quick Start\n\n```bash\n# Initialize\nchalk init --data-dir /var/lib/chalk --provider powerschool\n\n# Configure your SIS credentials in chalk.toml, then sync\nchalk sync --config /var/lib/chalk/chalk.toml\n\n# Start the admin console\nchalk serve --config /var/lib/chalk/chalk.toml --port 8080\n```\n\nSee [chalk.example.toml](chalk.example.toml) for a fully commented configuration template.\n\n## Build from Source\n\n```bash\ngit clone https://github.com/usechalk/chalk.git\ncd chalk\ncargo build --release\n# Binary at target/release/chalk\n```\n\nRequires Rust stable and SQLite3.
