TRIEL is an open specification language designed to generate correctness evidence at the point of translating specifications into implementations. It supports zero-knowledge predicates, conditional obligations, and standards compliance, helping bridge the gap between formal specifications and code to reduce costly failures and audit findings.
TRIEL sits in PulseGate's Frameworks & SDKs category. It focuses on preventing specification and implementation drift that leads to compliance failures and audit issues. It is built as an open-source project for developers and compliance engineers. TRIEL is open source under the Open Source license. The product ships for the web and the command line.
Behind TRIEL is Triel, and the product first shipped in 2026. Development happens publicly on GitHub with 19 commits in the last 90 days. Key capabilities include ZK Predicates, Deterministic Compilation, and Specification Language.
