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 /mfs as 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).
Larger pinsets require additional memory, with an estimated ~1 GiB of RAM per 20 million items for reproviding to the Amino DHT.
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.
Docker
Official images are published at https://hub.docker.com/r/ipfs/kubo/: 
#### 🟢 Release Images
Use these for production deployments.
- latest and release always point at the latest stable release
- vN.N.N points at a specific release tag
$ docker pull ipfs/kubo:latest
$ docker run --rm -it --net=host ipfs/kubo:latestTo customize your node, pass config via -e or mount scripts in /container-init.d.
#### 🟠 Developer Preview Images
For internal testing, not intended for production.
- master-latest points at HEAD of master
- master-YYYY-DD-MM-GITSHA points at a specific commit
#### 🔴 Internal Staging Images
For testing arbitrary commits and experimental patches (force push to staging branch).
- staging-latest points at HEAD of staging
- staging-YYYY-DD-MM-GITSHA points at a specific commit
Build from Source
git clone https://github.com/ipfs/kubo.git
cd kubo
make build # creates cmd/ipfs/ipfs
make install # installs to $GOPATH/bin/ipfsSee the Developer Guide for details, Windows instructions, and troubleshooting.
