Mirrors vs Topolog

Mirrors rebuilds the systems your AI agents call and replays real sessions against every prompt, tool, or model change before it reaches production.

Topolog is a goal planner that models your plans as a directed graph and allows you to execute tasks in order, then schedules your days around them.

About Mirrors

Mirrors rebuilds the systems your AI agents call and replays real sessions against every prompt, tool, or model change before it reaches production. Schema, seed data, and tool behavior mined into a runnable copy of the systems your agent calls, including the internal tools nobody will give you a test instance of. Every change is tested against past sessions before it merges. The Replay screen diffs each recorded production call against its counterpart in the environment, so you can see where the two agree and where they drift before you trust it with a merge gate.

About Topolog

Topolog is a goal planner that models your plans as a directed graph and allows you to execute tasks in order, then schedules your days around them. Topolog turns any goal into a dependency graph and schedules your days around it. Every plan is a real program, so the dates and odds are computed, not guessed. See the dependency structure, parallel branches, and where work bunches up, all in one canvas. Graph and list are two shapes of the same data, side by side.
