harumi

Run your local optimization code on Harumi's infrastructure — straight from your terminal or IDE — via the project's self-hosted Gitea repo, instead of pasting it into the platform's notebook editor.

Optimization/solver code (Gurobi, OR-Tools, etc.) is often too heavy to run on a laptop. harumi binds a local directory to a Harumi project, runs your code (from a git ref) on Harumi's infrastructure, and lets you inspect/download the results — reusing the exact same backend endpoints the web app and AI agent already use. It can also manage the project's repo, datasources, schedules, secrets, and organizations end to end.

Install

pip install harumi

This installs the harumi CLI and the harumi Python package (import harumi).

Installing from source instead (for contributing, or an unreleased fix):

pip install -e .

Quick start

# 1. Log in (Supabase OTP — check your email for the code)
harumi login

# 2. Create a new project, or find an existing one
harumi projects create "My Project"
harumi projects list

# 3. Bind the current directory to a project (skip if `projects create` already bound it)
harumi init --project <PROJECT_ID>

# 4. See available kernel sizes (CPU/RAM, Gurobi vs plain Python)
harumi specs

# 5. Run the bound directory's code on the infra
harumi run --watch --output-dir ./out

# 6. Inspect runs later
harumi runs list
harumi runs get <RUN_ID>

Everything else the CLI can do

• harumi repo — browse, read, write, delete, move, and download files in the project's Gitea repo; create/delete/promote branches (versions).
• harumi datasources — CRUD project database connections, test them, and run read-only SQL queries against them.
• harumi schedules — CRUD cron schedules that trigger git-ref runs.
• harumi secrets — CRUD project-scoped environment variables.
• harumi org — CRUD organizations and manage their members.
• harumi profile — view/update your account profile.

Run harumi --help or any subcommand with --help for the full flag reference, or see the command reference for endpoint-level detail.

Execution model

Every run is git-ref based: code lives in the project's Harumi Git (Gitea) repo. If your working tree is dirty or has unpushed commits when you run harumi run, the CLI transparently pushes a throwaway scratch branch so you can iterate without committing manually — your real branches are never touched. Pass --branch/--commit to run a specific ref instead.

Configuration & environments

The CLI targets one of two environments (each with its own Supabase, so each has its own login):

harumi env list          # production only (staging hidden unless --all / HARUMI_INTERNAL=1)
harumi env use staging   # internal devs; requires VPN + a staging account
harumi --env staging run # override for a single command

Selection precedence: --env > HARUMI_ENV > harumi env use (saved default) > production. Within an environment you can still override endpoints for local development:

Credentials (JWT + refresh token + Gitea token) are stored per-environment under ~/.harumi/environments/<env>/credentials.json (mode 0600) after harumi login. An older flat ~/.harumi/credentials.json is migrated into production automatically on first run.

Library usage

from harumi import Client
from harumi.config import ProjectBinding

binding = ProjectBinding.load()  # reads .harumi/config.json in cwd (or a parent)
client = Client()  # loads stored credentials

response = client.execute_project(binding.project_id, branch="main")

See the command reference for more examples (polling, repo edits, datasources, schedules, secrets, orgs).

Development

pip install -e ".[dev]"
pytest

All tests are offline (SSE parser + mocked HTTP transport) — no live backend required.
