Fyr

Fyr is an offline-first content platform for maps, books, and knowledge archives. It runs as a local web server and works without internet once content is present.

Project status: Fyr is currently in preview. Interfaces and workflows may continue to evolve.

• Single-service deployment — no external database, cache server, or sidecar services required
• Offline maps with PMTiles and MBTiles
• Library with EPUB, PDF, Markdown, and ZIM reading
• Native Fyr ZIM reader service with server-side archive access
• Local AI assistant for GGUF models
• Download queue and local content management for maps, books, models, POI, and misc files
• Tools: unit converters and encryption/ciphering utilities (AES, Base64, ROT13, hashing) — fully offline on your local Fyr deployment

The fastest way to try Fyr is with the official hosted installer:

Linux / macOS

curl -fsSL https://fyr.guide/install.sh | sh

Windows PowerShell

irm https://fyr.guide/install.ps1 | iex

The installer handles Docker setup, data persistence, and remembers your settings for future upgrades. To update later, add the update argument:

curl -fsSL https://fyr.guide/install.sh | sh -s -- update

If you need the compatibility-first legacy image on older hardware, use the installer shortcut:

curl -fsSL https://fyr.guide/install.sh | sh -s -- --legacy

irm https://fyr.guide/install.ps1 | iex; Install-Fyr -Legacy

See fyr.guide/#installation for the full installation guide, including manual Docker commands, building from source, and Raspberry Pi deployment.

If you have Rust installed and prefer to build locally:

cargo build --release -p server --bin fyr
./target/release/fyr

For a CPU-tuned local build on the same machine that will run Fyr, enable Rust's auto-detected native target features:

RUSTFLAGS="-C target-cpu=native" cargo build --release -p server --bin fyr
./target/release/fyr

PowerShell:

$env:RUSTFLAGS="-C target-cpu=native"
cargo build --release -p server --bin fyr
.\target\release\fyr.exe
Remove-Item Env:RUSTFLAGS

Open http://localhost:8080 on the same machine.

The canonical installation guide lives at fyr.guide/#installation and includes:

• Building from source for development workflows.
• Running with Docker (both Production and Dev releases) on an existing system.
• Installing and running Fyr on a clean Raspberry Pi OS setup.

Docker release tags are intentionally simple:

• hexagon/fyr:latest and hexagon/fyr:vX.Y.Z are optimized defaults.
• hexagon/fyr:legacy and hexagon/fyr:vX.Y.Z-legacy are compatibility-first fallbacks.
• hexagon/fyr:pc-legacy and hexagon/fyr:rpi-legacy are explicit legacy targets for older PCs and older Raspberry Pi-class arm64 hardware.

• Architecture and implementation details: /docs/developer/DEVELOPER_MANUAL.md
• Contributor workflow and validation requirements: /CONTRIBUTING.md

Fyr stores user content in a persistent data directory (./public/data by default, /data in Docker). See fyr.guide/#installation for persistence setup and the User Manual data layout section for folder-level details.
