DevLink is a peer-to-peer CLI toolkit that removes development and staging friction. It enables secure, direct sharing of environments, databases, repositories, services, and containers between developers, without staging servers, cloud costs, or insecure workarounds.

Modern development suffers from collaboration bottlenecks: pushing half-done commits just to unblock teammates, leaking secrets over chat apps, or waiting on staging to test a two-line change. DevLink replaces these with direct, ephemeral, encrypted connections - making collaboration as fast as running a command.

Core Features

• Ephemeral Staging Environments (hive) – Combine multiple developers’ local services into a shared, temporary test environment.
• Secure Environment & Secret Sharing (env) – Send .env files and secrets over one-time, encrypted transfers.
• Peer-to-Peer Git (git) – Serve your local repo directly for cloning/fetching. No WIP pushes required.
• Live Database Access (db) – Share a local database instantly, without dumps or imports.
• Instant Localhost Streaming (pair) – Expose localhost apps securely for demos and pair programming.
• Direct Docker Image Transfer (registry) – Push/pull Docker images between machines without registries.

Command Reference

devlink hive – Ephemeral Staging

Create a shared integration space across local machines.

• devlink hive create <name> – create a new hive, returns invite token
• devlink hive connect <token> – join an existing hive
• devlink hive contribute --service <name> --port <port> – expose a local service into the hive

# Example
devlink hive create feature-x
devlink hive contribute --service api --port 5000
devlink hive connect hx_abc123

---

devlink env – Secure Env Sharing

One-time, encrypted file transfers for secrets.

• devlink env send <file> – send file, returns code
• devlink env receive <code> <output> – receive file

devlink env send .env.local
devlink env receive 7-blue-river .env.local

---

devlink git – Peer-to-Peer Git

Serve your repo directly, no remote push required.

• devlink git serve – start temporary Git server
• git clone devlink://<code> <dir> – clone via DevLink transport

devlink git serve
git clone devlink://git_abc123 my-feature

---

devlink db – Database Sharing

Expose local databases for live queries.

• devlink db share --type <postgres|mysql> --port <port> – share DB
• devlink db connect <code> – connect to peer DB

devlink db share --type postgres --port 5432

---

devlink pair – Localhost Streaming

Securely share a local app over HTTPS.

• devlink pair --port <port> – stream local app

devlink pair --port 3000

---

devlink registry – P2P Docker Images

Skip Docker Hub; transfer images directly.

• devlink registry send <image:tag> – send image
• devlink registry receive <code> – receive image

devlink registry send myapp:latest
devlink registry receive 12-green-comet

---

Security Model

DevLink is secure by design:

• Zero-Trust – every session uses explicit, short-lived tokens
• Peer-to-Peer First – connections are direct when possible, no relays
• End-to-End Encrypted – no plaintext traffic, strong crypto by default
• Ephemeral – sessions vanish when stopped, no persistence
• No Inbound Ports – safe behind firewalls/NAT

---

Roadmap

• Multi-hop relays for restrictive networks
• GUI dashboard for hives
• Native packages (brew, apt, winget)
• IDE extensions (VS Code, JetBrains)
• Optional persistent hives for long-lived staging
