# Veritio > Veritio is a protocol-first, open-source evidence layer for application audit > events, hash-linked records, evidence graphs, and independently verifiable > export bundles. Veritio Cloud is a separate optional managed path. Veritio > supports evidence workflows; it is not legal advice or automatic compliance. The TypeScript, Python, and Go SDKs share language-neutral event semantics, canonical JSON, hashing, and deterministic redaction. The OSS path does not require a hosted account, hosted project, hosted key, or proprietary storage. ## Documentation - [Documentation overview](https://getveritio.com/docs/) - [Record your first event](https://getveritio.com/docs/start/record-first-event/) - [Hash chain](https://getveritio.com/docs/concepts/hash-chain/) - [Redaction](https://getveritio.com/docs/concepts/redaction/) - [Storage and self-hosting](https://getveritio.com/docs/storage/overview/) - [Agent events](https://getveritio.com/docs/ai/agent-events/) - [Veritio Cloud overview](https://getveritio.com/docs/cloud/overview/) - [Reference](https://getveritio.com/docs/reference/event-schema/) Every documentation page also has a static Markdown representation at the same path without the trailing slash and with `.md` appended. ## Agent discovery - [Structured documentation index](https://getveritio.com/agent-index.json) - [Bounded full documentation corpus](https://getveritio.com/llms-full.txt) HTML routes are canonical. The Markdown, JSON, and full-text files are generated from the same verified content for retrieval and citation; their presence does not guarantee selection, citation, or ranking by any search or agent system. ## Product - [Product](https://getveritio.com/product/) - [Open source](https://getveritio.com/open-source/) - [Veritio Cloud](https://getveritio.com/cloud/) - [Pricing catalog](https://getveritio.com/pricing/) - [Examples](https://getveritio.com/examples/) - [Changelog](https://getveritio.com/changelog/) ## Source - [Veritio OSS](https://github.com/getveritio/veritio) - [Website](https://github.com/getveritio/veritio-website)
