Shared content-addressable cache for builds, packages, and ML.
CoreLink deduplicates and audits the blobs your CI, your registries, and your model store re-upload a hundred times a day — across regions, across workloads, across teams — with cryptographic tenant isolation and an append-only Merkle audit chain.
No card required to start · Free tier with R2 zero-egress

A 90-second walkthrough: point your build cache at CoreLink, watch a cold build go warm, and read the signed audit trail.
The difference between marketing-language multi-tenant and actually-multi-tenant is a formal proof. CoreLink keeps a TLA+ specification of cross-tenant byte non-leakage and runs it in CI on every change. If the safety property regresses, the build fails. We don't trust ourselves to get this right by code review alone.
Every CAS read and write appends to a per-tenant append-only Merkle log. Each entry is Ed25519-signed. The full log is replayable. You can answer the auditor's question — what happened on this artefact, when, and has anything been retro-edited? — with a cryptographic proof, not a vendor's word.
Active in US-East, EU-West, AP-Southeast, and AU-East on Cloudflare R2 + Workers + D1. Reads route locally; writes converge globally; residency policies are enforced per tenant — not assumed and not opt-in. EU bytes stay in EU. AU bytes stay in AU.
