AI coding tools have fundamentally changed how software gets built. Developers are shipping more code, faster, with less friction than ever before. But the organizations benefiting most from AI-accelerated development are running into the same wall: quality hasn't kept pace.
More code means more surface area for bugs. More PRs means more review burden on senior engineers. More releases means more chances for regressions to reach customers. The bottleneck has moved from writing code to verifying it, and verification is still largely manual.
Checksum is a continuous quality platform built for this reality. Its suite of AI agents autonomously generates, runs, and maintains tests across every layer of the software development lifecycle: end-to-end UI flows, API endpoint coverage, and PR-level CI validation, so engineering teams can move fast without sacrificing reliability.
What sets Checksum apart: it doesn't wait for instructions. It works as a background agent, continuously monitoring your codebase, generating tests for what matters, and repairing broken tests as the product evolves. Seventy percent of test failures resolve automatically, eliminating the maintenance burden that causes most test suites to decay and get abandoned.
Every test Checksum produces is real, Playwright code you own, submitted as a PR to your repository. No vendor lock-in. Teams keep full control.
Checksum is fine-tuned on 1.5+ million test runs and integrates natively with Cursor, Claude Code, and 100+ AI coding agents via /checksum slash commands. Testing happens before code review, not after. Generation and healing run on Checksum's cloud, consuming no LLM tokens or local resources.
The bottom line: Checksum gives engineering teams the confidence to ship at the speed AI makes possible.

Okyline is an Executable Data Design (EDD) platform that transforms validation contracts into executable operational assets for enterprise data quality.
Instead of multiplying specifications, custom validators, monitoring scripts, tests, and reporting layers, Okyline relies on a single readable contract shared across validation, quality control, and operational monitoring activities.
The contract itself becomes executable and directly drives deterministic validation, advanced business invariant verification, multi-format processing, data quality gates, operational metrics, and historical quality analytics.
Okyline validates APIs, enterprise events, files, streaming payloads, LLM structured outputs, and distributed data flows while continuously producing measurable quality indicators, completeness statistics, validation traces, and error propagation insights.
Because contracts are created from annotated sample data, validation rules remain immediately understandable for developers, architects, QA teams, integration specialists, and business analysts.
The Community Edition includes the public specification, a free Java validation runtime, a Claude AI assistant for contract generation, JSON Schema transpilation support, and a free online studio for executable JSON contracts.
The Enterprise Edition extends the same contract-centric model to native validation of JSON, JSONL, XML, CSV, FIXED, and EDI flows, combined with operational quality dashboards, data quality gates, and long-term quality tracking capabilities, all without requiring databases, warehouses, or centralized infrastructure.

Solidity Fuzzing Boilerplate
The Solidity Fuzzing Boilerplate acts as a crucial starting point, aimed at streamlining the fuzzing procedure for diverse aspects of Solidity projects, especially libraries. Developers can write their tests once and seamlessly run them with the fuzzing tools provided by both Echidna and Foundry. When different Solidity versions are needed for certain components, these can be easily deployed within a Ganache instance using Etheno. For generating complex fuzzing inputs or performing differential fuzzing by comparing results with non-EVM executables, HEVM's FFI cheat code is a highly effective tool. Furthermore, results from fuzzing experiments can be shared without worrying about licensing implications by adjusting the shell script to pull specific files. If your Solidity contracts will not utilize shell commands, it is wise to disable FFI, as it can slow down processes and should mainly be seen as a workaround. This feature is particularly advantageous when testing intricate implementations that are hard to reproduce in Solidity but can be found in other programming languages. It is crucial to carefully examine the commands executed before initiating tests in projects with FFI enabled, to ensure a thorough understanding of the actions being performed. Maintaining clarity in your testing methodology is vital for upholding the integrity and effectiveness of your fuzzing initiatives, and it ultimately enhances the overall reliability of the project.
