// the search engineering layer
Your search team is doing too much.
Learn how hev layer simplifies your search team concerns.
# jobs to be done
Search teams need to solve many of the most complex and expensive jobs to be done in your org's data platform. Most of them have nothing to do with making search better for users.
// ship embeddings
Building CUDA images, writing Kubernetes autoscalers, managing Spark — the time sink every search team underestimates, and managed services trade one kind of pain for another. Layer collapses it: declare a Python UDF and layer runs the work on CPU or GPU, scaling pods and nodes between bursts.
Read the Docs// stay consistent
Keeping the index in sync with source data usually means hand-rolled watchers and event hooks glued together by the team that wrote them. Layer ships the operator: it scans the index for consistency, watermarks state changes, and rolls up facets your application can read directly.
Read the Docs// serve fetches
Whether it's a near-bottomless queue for building your pipeline, or serving full datasets from a pull-through cache, your search system needs O(1) read/write capabilities. Layer ships Aerospike as a production-hardened document cache with NVMe price:performance.
Read the Docs// see search
Observability in 2026 has plenty of options and still demands plumbing. Layer bundles clickstream from the doc cache and operational metrics from the gateway into an opinionated dashboard, backed by a PromQL-compatible time series.
Read the Docs// scope access — coming soon
Today every search team inside a multi-tenant product writes the auth proxy themselves: scope API keys to namespaces, gate the write paths, ship audit events somewhere security will accept. Layer ships scoped keys, per-namespace RBAC, and an audit feed — the pattern your security team always asks for, as a primitive.
// track cost — coming soon
Today "what does search cost us per million docs" is a question nobody can answer in under a week. AWS line items live in one bill, Turbopuffer in another, GPU pool minutes nowhere obvious. Layer pulls every line item into one invoice and derives the unit metrics — cost per million docs, cost per TiB indexed, cost per query — that scrub with the timeframe.
# layer run— coming soon
Ever needed to backfill your production data? With layer that's as easy as creating a docker container. Layer handles compute, and can backfill as much or as little of your index as you specify.
$ layer run -f udf.yaml --index products

# what's in the box
hev layer is a BYOC product installed with Terraform and Helm. Read the Docs.
See the docs for the full SBOM.
# vector systems
Layer puts one operator surface in front of whichever vector store the team already chose. Turbopuffer is the backend Layer runs against today; the rest are next.
# design preview / ready today
The current program is for teams with a Turbopuffer-shaped retrieval path and a search team small enough to feel every concern on this page.
