Stop guessing what powers your projects
The connective layer for your tech stack. Map what services power each project, track costs, discover alternatives, and stop guessing what you're paying for.
Investigation Board
A visual map of every service in your project, arranged in an orbital layout with your project at the centre. Click to launch any dashboard. Right-click to draw dependency lines.
Service Discovery
Browse curated recommendations by category — frontend, backend, auth, database, payments, hosting, and more. Each service explained in plain English with one-click add.
Cost Tracking
Record what you pay, how often, and which card you're using. See monthly totals per project. Spot services you're paying for but not using.
Health Insights
Automatic signals: overlapping categories, missing critical services, broken access links, shared dependency risks. Problems you wouldn't spot on your own.
Built for indie developers
You followed a tutorial, signed up for six services, got something working. Now you have accounts scattered everywhere. We've been there. Interstitium gives you the full picture.
