Execute and capture all outputs as structured evidence.
Perfect for compliance, research, and regulated environments where provenance matters.
An evidence warehouse is a collection of executable notebooks that generate and store proof of work.
Every query, transformation, and result is captured with timestamps, inputs, and outputs.This creates an immutable audit trail.
Track where data came from, how it was transformed, and who ran the pipeline
Rerun any notebook and get the same results. Critical for audits.
Meet regulatory requirements with automatically generated evidence
Spry runs each fenced block (SQL, Bash, JSON, etc.) and captures the output.
Timestamps, user info, execution duration, and environment details are stored alongside results.
Results are saved as structured JSON, database records, or files. This creates a permanent evidence trail.
Markdown notebooks are versioned in Git, ensuring historical evidence is never lost.
Generate audit trails for financial calculations, risk assessments, and regulatory reporting
Document data analysis pipelines for FDA submissions and peer review
Prove how training data was processed and what context was used for inference
Track data lineage and transformations for GDPR and privacy compliance
Generate test evidence showing what was checked and when
Share analysis pipelines that anyone can rerun to verify results
Spry notebooks can be scheduled to run automatically, generating fresh evidence on a regular cadence.
Store evidence in append-only databases or immutable storage systems for maximum trust.
Traditional documentation goes stale the moment it is written. Spry notebooks execute, so documentation is always up-to-date with reality.
When auditors ask "How was this calculated?", you can show them the exact Markdown notebook that generated the evidence. They can rerun it themselves to verify.
