Sift Stack

Sift (siftstack.com) is a unified observability platform for mission-critical hardware — the telemetry layer for rockets, aircraft, robots, energy systems and autonomous vehicles. Founded by former SpaceX engineers Austin Spiegel and Karthik Gollapudi and headquartered in Marina del Rey, California, Sift ingests, stores and analyzes high-rate, high-cardinality sensor data, then layers automated rule-based anomaly detection, run-to-run comparison and certification-ready reporting on top of it. The product surface is unusually complete for a company this size: a 343-operation REST API transcoded from 330 gRPC RPCs across 66 MIT-licensed .proto files, first-party Python, Rust, Go, C++ and LabVIEW clients, a sift-cli binary, outbound HMAC-signed webhooks, and a Grafana datasource. It is also one of the more agent-ready providers in the catalog — it publishes an A2A agent card, an Agent Skill, llms.txt on two hosts, an anonymous remote MCP documentation server, and a second MCP server that ships inside the CLI and talks to a customer's own Sift environment. Deployment spans SaaS, private cloud, on-premises, airgapped and AWS GovCloud, backed by SOC 2 Type II, NIST SP 800-171 and ITAR compliance.

Sift Stack publishes 45 APIs on the APIs.io network, including Annotation Log Service API, Annotation Service API, API Key Service API, and 42 more. Tagged areas include Observability, Telemetry, Aerospace, Defense, and Robotics.

The Sift Stack catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Sift Stack’s developer surface includes documentation, API reference, getting-started guide, engineering blog, signup flow, changelog, FAQ, and 25 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. This rating is computed from github.com/api-evangelist/sift-stack: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
