🎯 Pitaya

Orchestrate AI coding agents (Claude Code, Codex CLI) with pluggable strategies and a clean TUI.

Note: Pitaya is in public beta. Interfaces and defaults may evolve.

What It Does

• Runs multiple agents in parallel and helps you pick the best result
• Uses per‑task branches in your repo to keep alternatives safe and reviewable
• Displays a clean, adaptive TUI with live progress, costs, and tokens
• Supports custom Python strategies for multi‑stage workflows

Built‑in strategies: simple, scoring, best‑of‑n, iterative, bug‑finding, doc‑review

Demo

Watch a short video demo of the TUI and orchestration:

Install

pip install pitaya
# or
pipx install pitaya
# or
uv tool install pitaya

Build the Docker image

Pitaya runs agents inside Docker. You need a Docker image that contains the agent CLI(s) you plan to use:

• claude (for --plugin claude-code)
• codex (for --plugin codex, Pitaya bundles @openai/[email protected] by default)

You can build a ready‑to‑use image from this repository’s Dockerfile:

git clone https://github.com/tact-lang/pitaya
cd pitaya
docker build -t pitaya-agents:latest .

Prefer a custom image? Use any base you like as long as it includes the required CLI(s) above. You can point Pitaya to a different image via --docker-image or set runner.docker_image in pitaya.yaml.

Authenticate:

• Claude Code: set CLAUDE_CODE_OAUTH_TOKEN (subscription) or ANTHROPIC_API_KEY
• Codex CLI: set CODEX_API_KEY (preferred). Pitaya also auto-detects OPENAI_API_KEY, OPENROUTER_API_KEY, GROQ_API_KEY, etc., plus optional base URLs such as OPENROUTER_BASE_URL.

Quickstart

From the root of a git repo:

pitaya "Create a HELLO.txt file with 'Hello from Pitaya' text in it and commit it"

More examples:

# Parallel candidates with scoring (pick the best)
pitaya "Write the funniest and most original joke possible" --strategy best-of-n -S n=5

# Iterative refine (generate → review → refine)
pitaya "Write the funniest and most original joke possible" --strategy iterative -S iterations=3

# Headless JSON output (pure NDJSON)
pitaya "task" --json

OpenRouter (Codex plugin) example:

pitaya "Write the funniest and most original joke possible" \
  --plugin codex \
  --model "gpt-5.1-codex" \
  --api-key "$OPENROUTER_API_KEY" \
  --base-url https://openrouter.ai/api/v1

Configuration (peek)

Optional pitaya.yaml to set defaults:

model: sonnet
plugin_name: claude-code
orchestration:
  max_parallel_instances: auto
  branch_namespace: hierarchical

CLI overrides config; -S key=value only affects the selected strategy.

Results & Logs

• Logs: logs/<run_id>/events.jsonl and JSONL component logs (orchestration.jsonl, runner.jsonl, tui.jsonl, other.jsonl)
• Results: results/<run_id>/ (summary.json, metadata.json, branches.txt, instance_metrics.csv, instances/.json)
• Branches: pitaya/<strategy>/<run_id>/k<short8> (hierarchical namespace)
• Resume: pitaya --resume <run_id>

Contributing

Issues and PRs are welcome. This project is evolving—feedback on UX, strategies, and plugin support is especially helpful.
