No more 3am pages from broken pipelines.\n\n```\nProducer: \"I want to drop user_email\"\n    ↓\nTessera: \"3 teams depend on this. Notifying them.\"\n    ↓\nConsumers: \"We've migrated. Approved.\"\n    ↓\nProducer: Ships v2.0.0 safely\n```\n\n## Quick Start\n\n```bash\n# Docker (recommended)\ndocker compose up -d\nopen http://localhost:8000\n\n# Or from source\nuv sync --all-extras\ndocker compose up -d db  # PostgreSQL\nuv run uvicorn tessera.main:app --reload\n```\n\n## Key Features\n\n- **Schema contracts** - JSON Schema, Avro, OpenAPI, and GraphQL support\n- **Breaking change detection** - Auto-detect incompatible changes\n- **Consumer registration** - Track who depends on what\n- **Proposal workflow** - Coordinate changes across teams\n- **Multi-source imports** - dbt manifests, OpenAPI specs, GraphQL schemas, Avro registries\n- **Web UI** - Visual interface for managing contracts\n\n## Global Search\n\nSearch across teams, users, assets, and contracts:\n\n```bash\ncurl \"http://localhost:8000/api/v1/search?q=payments\u0026types=assets\u0026types=contracts\u0026limit=5\"\n```\n\n## Configuration\n\nWebhook settings (optional):\n\n- `WEBHOOK_URL` - Destination for webhook events\n- `WEBHOOK_SECRET` - HMAC secret for webhook signatures\n- `WEBHOOK_ALLOWED_DOMAINS` - Comma-separated domain allowlist (e.g. `example.com,webhooks.mycorp.com`)\n\n## How It Works\n\n1. **Producers** publish contracts (schema + guarantees) for their data assets\n2. **Consumers** register dependencies on contracts they use\n3. **Breaking changes** create proposals requiring consumer acknowledgment\n4. **Non-breaking changes** auto-publish with version bumps\n\n## Documentation\n\nFull documentation at [ashita-ai.github.io/tessera](https://ashita-ai.github.io/tessera):\n\n- [Quickstart Guide](https://ashita-ai.github.io/tessera/getting-started/quickstart/)\n- [Python SDK](https://ashita-ai.github.io/tessera/guides/python-sdk/) | [PyPI](https://pypi.org/project/tessera-sdk/)\n- [dbt Integration](https://ashita-ai.github.io/tessera/guides/dbt-integration/)\n- [API Reference](https://ashita-ai.github.io/tessera/api/overview/)\n\n## License\n\nMIT\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fashita-ai%2Ftessera","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fashita-ai%2Ftessera","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fashita-ai%2Ftessera/lists"}
