pipestat
A pipeline results reporter
Decision gist · record as of 2026-08-14
Yes. Pipestat is actively maintained, has no known vulnerabilities, and solves a real problem—standardizing how pipelines report and store results. Low install friction and permissive licensing make it a safe choice. Best suited for projects that need schema-validated result storage across multiple pipeline stages or tools; less critical for simple single-stage pipelines with ad-hoc output handling.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- PostgreSQL backend tests require a running PostgreSQL instance, but YAML file backend works without external dependencies.
- Low install friction with a pure-Python wheel distribution.

What it is and what it does
Pipestat is a results management layer for computational pipelines. A pipeline author defines expected outputs in a YAML schema (specifying types, descriptions, and validation rules), then uses pipestat's API to report results as the pipeline runs. Results are validated against the schema and persisted to either a YAML file or PostgreSQL database. Downstream tools and users retrieve those results through the same API, ensuring consistent structure and validation across the pipeline ecosystem.
The package is built on seven runtime dependencies—eido, jinja2, jsonschema, logmuse, pyyaml, ubiquerg, and yacman—that handle schema management, templating, validation, logging, and configuration. It targets modern Python (3.10+) and is actively maintained. The design separates schema definition from result reporting, making it suitable for multi-stage pipelines where different tools need to write and read results in a standardized format.
Use it for
- Define a schema for bioinformatics pipeline outputs, then report accuracy, processing time, and file paths as the pipeline executes.
- Store computational results in PostgreSQL for downstream querying and aggregation across multiple pipeline runs.
- Auto-generate a schema from existing pipeline results files to enforce structure on future runs.
- Share pipeline outputs between heterogeneous tools by using pipestat as a common results API.
- Validate pipeline outputs against a schema before storing them, catching malformed results early.
