Verification GitHub Repositories (2026) · Open Source Tools

Find, verify, and analyze leaked credentials

Stop your AI from making things up — it proposes, deterministic tools decide, every claim checked against ground truth with evidence. Grounded facts and context survive resets. Reverse engineering is the proving ground. MCP server + CLI.

Creusot helps you prove your Rust code is correct.

A model checker for Rust programs.

Autonomous development for real products. Governed agents build from specs you approve, follow the rules you set, and nothing merges until another agent proves it. Your decisions, judgement and taste are the bar that work must clear. Declare your vision and let agents build it.

Agent Skill for complex work: research before asking, ask before planning, plan before building, verify before delivering, independent review before calling it done. Plain text, no runtime.

TLC is a model checker for specifications written in TLA+. The TLA+Toolbox is an IDE for TLA+.

Neuro-symbolic agents with verified memory. MCP math tools, an algebra repair Skill, and an open challenge. Verify solutions, learn checked rules, and reuse.

Automatic verification of LLVM optimizations

Digital Design Equivalence Checking

CPAchecker, the Configurable Software-Verification Platform (read-only mirror)

scores: Metrics for the verification, evaluation and optimisation of forecasts, predictions or models.

Open-source ARM64 execution lab in safe Rust: run programs on three CPU engines and prove the results match real hardware.

Provides email verification on the go.

Vonage Server SDK for Java. API support for SMS, Messages, Voice, Text-to-Speech, Numbers, Verify (2FA), Video and more.
