Verdicts
Agent Development Kit (ADK)
Python, TypeScript, Go, Java and Kotlin. Two critical CVEs in 2026, one of them in tool confirmation itself.
guilds.run
A self-hosted multi-agent system that records each run's prompt, tool calls and memory changes, with per-agent models and tools and no telemetry by default. Public since 9 October 2026, it has no tagged release or published package, its own security register lists 13 open issues, and the site's terms and privacy links return 404.
Before you call either
Agent Development Kit (ADK)
- Upgrade to 2.5.0 or later before relying on tool confirmation
- Always pass tool_filter to McpToolset
- Pin a 2.x minor and read the changelog's breaking section before each bump
- Install the bigquery-analytics extra if you use pyarrow, since 2.7.0
- Keep ADK Web off public interfaces, or run 1.28.1 or later at the least
guilds.run
- Keep the box on loopback or behind an authenticating proxy with AUTH_MODE=trusted-header. The default mode does not authenticate
- Put agents that hold different secrets or GitHub tokens on different machines. Agents on one machine can read each other's homes and tokens
- Back up the .env file written by ./setup.sh. It holds the only copy of the key that encrypts stored credentials
- Set a spend limit at your model provider. guilds.run sets no spend cap, and max_tool_calls defaults to 50 per run
- Pin a commit of main when you deploy. There are no tagged releases or versioned images yet
