FosterStack

Product: FosterStack is a self-hosted remote build cache server intended as a replacement for Develocity Build Cache Node.
Build tools: It supports Gradle and implements the Apache Maven Build Cache Extension remote HTTP mode, with Maven acceptance coverage in progress.
Cache management: The server provides size-capped LRU eviction to make room for new entries.
Authentication: It supports HTTP Basic Auth over TLS, with constant-time credential comparison and no credential logging.
Metrics: It exposes Prometheus metrics and provides a read-only status page with hit rates and cache size versus cap.
Deployment: The product is self-hosted and can be run from a Docker image or as a static binary.
Operating systems: Release binaries are available for Linux amd64 and arm64 and macOS amd64 and arm64; Windows is not built or planned.
Security: The core is MIT-licensed, releases include signed artifacts and SLSA provenance, and security patches are included in the free tier.
Privacy: The maker says the free core makes no outbound connections and collects no telemetry or usage data.
Compliance: FosterStack says it is not FedRAMP or CMMC compliant; its published evidence and validated crypto are intended to support a customer's compliance program.
Support: Bugs and questions can be reported through GitHub issues; the listed paid tiers describe email and priority support but are not yet available.
Maturity: The maker identifies the product as v0.1 and says nobody outside its own work is yet running it in a production build pipeline.
Intended users: The product is aimed at teams using Gradle or Maven that want a self-hosted replacement for the discontinued standalone Develocity Build Cache Node.
Price from: $41.58/mo
