Tern Systems

Tern automates code migrations, cutting the effort required by 90%. Remember the beginning of that last project? Everything is new. Easy to change. But as it takes shape, there's an inertia that sets in. Bitrot starts to pull everything backwards. The code on the screen starts to feel more important than the ideas in our heads. The grind of security updates, dependency bumps, and making the same change in 500 places across 12 repos is suddenly an everybody problem. That's the cost of maintenance. At Tern, we want to make it as easy to maintain a 100m line codebase as a 100-line one. We combine AI, structured code search, AST parsing, and real-world migration techniques to maximize automation while maintaining accuracy. We've wrapped in up in an easy-to-use platform that gets your entire team on the same page and lets you blast through even the biggest changes safely.
