What it does
Periscope gives you a live view into the context window of your coding agent. As a session grows, you can see what’s been loaded, what’s been overwritten, where the agent is drifting, and when it’s the right moment to fork or reset.
Why it exists
Engineers who use coding agents hit the same wall over and over: the agent feels confused, the answers get worse, and you don’t know whether the problem is the prompt, the context, or the model. Today there’s almost no visibility into what the agent is actually working with at any given moment.
We built Periscope to make that visible - a microscope, not a black box.
Tech Stack
Go on the backend, Svelte and TypeScript on the frontend.
Recognition
Periscope was a hackathon project. We were finalists, and a number of engineers who saw the demo told us it was solving a real pain point in their day-to-day work with agents.
