Paste a model. Get a solution.
LP format in, JSON out. Load an example or paste your own — this solves live on Ceris.
Ceris is serverless optimization infrastructure. Send your problem — portfolio allocation, scheduling, resource planning — and get production-grade results back in seconds.
No solver license. No infrastructure. No OR team. Just an API.

Ceris routes your problem to HiGHS or OR-Tools, handles parallelization and scaling, and returns results with a full audit trail. There is no infrastructure to manage and nothing to provision.

}HiGHS and OR-Tools handle scheduling, allocation, and portfolio problems — no commercial license required.
No infrastructure to provision, no DevOps team to hire. Idea to production in an afternoon.
No annual license sitting idle 9 months a year. Pay per solve, not per seat.
Run the same problem against HiGHS and OR-Tools at once. Already have Gurobi? Bring it along.
Input and output hashes plus an Ed25519 signature on every solve, verifiable by anyone against our published key. Ceris never stores your model — you hold the evidence, we hold the attestation.
