The short version
Coshell starts from the terminal. Teams share a persistent development workspace with agent sessions, access controls, attribution, and audit history.
SignalsAI starts from the team conversation. Stakeholders and developers clarify an idea, approve requirements, and carry that context into a private build window.

Where Coshell is strong
Terminal-native collaboration
Engineers can share the development surface they already use for code and agents.
Model flexibility
Teams can use free OpenCode gateway models or bring their own model keys.
Free self-hosted entry point
The $0 edition has no seat fees and can run on a team-managed server.
Enterprise controls
Enterprise offers SSO, role-based access, an audit trail, priority support, and scaled on-premises operation through contact sales.
What SignalsAI adds
Accessible beyond the terminal
Product, design, and business stakeholders can shape the work without joining a coding session.
Decisions and requirements are explicit
Agent questions become decisions connected to the PRD and technical specification.
A lifecycle rather than a session
Five phases, 33 stages, and 14 agents organize work before and after coding.
Customer-controlled environment
SignalsAI does not access customer code, and the SignalsAI AI-DLC application supports self-hosting.
Which is the better fit?
Choose Coshell
Your engineering-led team wants a shared terminal and agent environment that it can operate itself.
Choose SignalsAI
Product and engineering need to agree on requirements and preserve that reasoning across the lifecycle.
