Kubo: IPFS Implementation in Go
The first implementation of IPFS.
What is Kubo? | Quick Taste | Install | Documentation | Development | Getting Help
What is Kubo?
Kubo was the first IPFS implementation and is the most widely used one today. It takes an opinionated approach to content-addressing (CIDs, DAGs) that maximizes interoperability: UnixFS for files and directories, HTTP Gateways for web browsers, Bitswap and HTTP for verifiable data transfer.
Features:
- Runs an IPFS node as a network service (LAN mDNS and WAN Amino DHT)
- Command-line interface (
ipfs --help) - WebUI for node management
- HTTP Gateway for trusted and trustless content retrieval
- HTTP RPC API to control the daemon
- HTTP Routing V1 client and server for delegated routing
- FUSE mounts for mounting
/ipfs,/ipns, and/mfsas local filesystems (experimental) - Content blocking for public node operators
Other IPFS implementations: Helia (JavaScript), more...
Quick Taste
After installing Kubo, verify it works:
$ ipfs init
generating ED25519 keypair...done
peer identity: 12D3KooWGcSLQdLDBi2BvoP8WnpdHvhWPbxpGcqkf93rL2XMZK7R
$ ipfs daemon &
Daemon is ready
$ echo "hello IPFS" | ipfs add -q --cid-version 1
bafkreicouv3sksjuzxb3rbb6rziy6duakk2aikegsmtqtz5rsuppjorxsa
$ ipfs cat bafkreicouv3sksjuzxb3rbb6rziy6duakk2aikegsmtqtz5rsuppjorxsa
hello IPFS
Verify this CID is provided by your node to the IPFS network: https://check.ipfs.network/?cid=bafkreicouv3sksjuzxb3rbb6rziy6duakk2aikegsmtqtz5rsuppjorxsa
See ipfs add --help for all import options. Ready for more? Follow the command-line quick start.
Install
Follow the official installation guide, or choose: prebuilt binary | Docker | package manager | from source.
Prefer a GUI? Try IPFS Desktop and/or IPFS Companion.
Minimal System Requirements
Kubo runs on most Linux, macOS, and Windows systems. For optimal performance, we recommend at least 6 GB of RAM and 2 CPU cores (more is ideal, as Kubo is highly parallel).
[!IMPORTANT] Larger pinsets require additional memory, with an estimated ~1 GiB of RAM per 20 million items for reproviding to the Amino DHT.
[!CAUTION] Systems with less than the recommended memory may experience instability, frequent OOM errors or restarts, and missing data announcement (reprovider window), which can make data fully or partially inaccessible to other peers. Running Kubo on underprovisioned hardware is at your own risk.
Official Prebuilt Binaries
Download from https://dist.ipfs.tech#kubo or GitHub Releases.
