Show HN: Excalibur. The open-source AI coding agent for product engineers

3 months ago

Excalibur is an AI coding agent designed for product engineers, covering the entire product cycle: discover, build, verify, and ship.
It features five core capabilities: time-travel for work runs with immutable event logs, discovery for scoping work items, a web dashboard for task management, support for any AI model provider, and handling the full product cycle beyond just coding.
The tool ensures safety with approval gates, sandboxed execution, secret protection, isolated branches, redacted prompts, and an inspectable audit trail.
Excalibur offers multiple workflows and methodologies, including structured features, security-first approaches, and discovery phases, with customizable options via YAML or an SDK.
It includes both a free open-source core version and an enterprise version with additional features like governance, compliance, team coordination, and scalability for organizations.
