Basically the title.

Most of my computers are at least 13 years old.

✅ Minimum System Requirements (Local / Small Use)
Suitable for intranet mode, testing, or light local crawling.

CPU: 2-core CPU (Intel/AMD x86_64, or ARM64)
RAM: 2 GB minimum (4 GB recommended)
Disk Space: 2–5 GB (base install + ~100k URLs)
Java: Java 11+ (OpenJDK 17 preferred)
OS: Linux, Windows, macOS, BSD, ARM SBCs (like Raspberry Pi)
Network: Localhost or open ports for HTTP (8090) and P2P (40000+)

---

⚙️ Recommended Specs for Stable Operation
Ideal for public crawling, light P2P sharing, and consistent uptime.

CPU: 4+ cores (Xeon, Ryzen, Core i5+)
RAM: 8–16 GB (Java heap: 4–6 GB)
Storage: SSD preferred; 20–100 GB depending on crawl size
Java: OpenJDK 17 LTS or newer
OS: Linux (Ubuntu 20.04/22.04, Debian 11+)

---

🚀 Advanced or High-Performance YaCy Nodes
For indexing millions of URLs, long-running peers, or integrated front-ends.

CPU: 8–32 threads (Xeon E5, Ryzen 9, Core i7+)
RAM: 32–384 GB
Java Heap: 8–48 GB (configured in JAVA_ARGS)
Storage: RAID SSDs or NVMe; 1–10 TB
Index Speed: 500–10,000 URLs per minute (with tuning)
Optional: RAM-disk or ZRAM-backed DATA/INDEX folders

📦 Installation Size & Memory Usage

Use Case | Index Size | Disk Used | Avg RAM Used -- | -- | -- | -- Fresh install | 0 URLs | ~400 MB | ~200–300 MB Small crawl (~100k URLs) | ~500 MB index | 2–5 GB | ~500 MB–1 GB Large crawl (~5M URLs) | 5–10 GB index | 10–50 GB | 4–10 GB Full peer w/ sharing (25M–100M) | 20–300+ GB index | 20–1500 GB+ | 8–48 GB

---

Notes:

• Java 17 is highly recommended.

• SSDs improve responsiveness, especially with large indexes.

• Configure heap size via JAVA_ARGS in startYACY.sh.

• Use REST/API mode and disable GUI for headless peers.

• RAM-disk or tmpfs can boost indexing speed significantly.

basically described here: https://yacy.net/installation/requirements/
which is of older origin, but possibly still up-to-date.
i've never met a machine, which couldn't run yacy, so far.
some people run even on android or raspberry pi.
but the requirements basically depend on what you do with your instance, whether you crawl a lot, keep a large index or just search using p2p network.
