Your own Git forge

An open-source, self-hosted home for repositories and coding-agent workflows.

exist.io is an open-source, self-hosted Git forge built for software engineering teams and autonomous AI coding agents. It provides a reliable home to host code, collaborate through pull requests and reviews, enforce enterprise security rulesets, and connect coding agents through dedicated, permission-aware interfaces.

The goal is simple: keep your repositories, collaboration history, and agent integrations on infrastructure you control.

Core capabilities

Your repositories: Own your data, Git packfiles, and SQLite database with zero external vendor lock-in.
Dual Git transports: Pure-Go Smart-HTTP and native SSH server on port 2222 with zero host daemon requirements.
Git LFS & CAS storage: RFC-compliant Git Large File Storage v1 Batch API and file locking.
Cryptographic verification: Real-time OpenSSH SIGSPEC and GPG commit signature audits in the Web UI.
Enterprise Federation: OIDC & SAML 2.0 Single Sign-On and RFC 7644 SCIM 2.0 user sync.
Agent integrations (MCP): Embedded Model Context Protocol server exposing 34 specialized tools at /mcp.
Infrastructure as Code: Official Terraform / OpenTofu provider and Kubernetes Helm chart.
Policy & compliance: Branch and tag rulesets, bypass actor hierarchies, status check enforcement, SSH CAs, and CIDR allowlists.

Find your way around

Getting started quickly

exist.io compiles to a single self-contained binary without cgo. You can initialize a new forge, create an administrative workspace, and start serving Git repositories and agent workflows in minutes:

# Build the server daemon
go build -o bin/existd ./cmd/existd

# Initialize storage and primary administrator
./bin/existd bootstrap --email admin@example.com --namespace acme --data-dir ./data

# Start the forge daemon
./bin/existd
