photon vs initrunner
photon: Photon lets you define logic once in TypeScript and automatically exposes it through three interfaces: MCP server for AI agents, CLI tool for automation, and Web UI for humans. It eliminates boilerplate by deriving tool definitions, validations, and UI from your code, making it easy to build and deploy multi-surface applications.; initrunner: InitRunner lets you define an agent in one YAML file, chat with it, run it autonomously, and deploy it as a daemon triggered by cron, file changes, webhooks, or Telegram messages. It supports multiple execution modes, built-in memory, cost controls, multi-agent orchestration, and security features. Built on PydanticAI.

TL;DR
Choose photon if…Building AI agent tools with MCP protocol support
Choose initrunner if…Automated code review: set up a daemon that reviews pull requests or file changes.

Features
photon01Auto-generated Web UI from method signatures
02One source file produces MCP server, CLI, and UI
03Built-in support for OAuth, scheduled tasks, webhooks, and distributed locks
04Standalone binary compilation via Bun
05Real-time events and persistent memory without infrastructure
initrunner01One file, four modes: interactive REPL, one-shot prompt, autonomous loop, and daemon with triggers.
02Autonomous execution with task decomposition, reasoning strategies, and guardrails (iteration, token, time budgets).
03Daemon mode with six trigger types: cron, webhook, file_watch, heartbeat, Telegram, Discord.
04Built-in memory (semantic, episodic, procedural) that persists across sessions and agents.
05Security features: input validation, tool authorization (InitGuard), sandboxed code execution, tamper-evident audit trail, encrypted credential vault.
