Engineering teams shipping with AI have a new bottleneck: validation. Code output has accelerated. Quality hasn't. Checksum closes the gap.
Checksum is a continuous quality platform with a suite of AI agents that handle testing end-to-end, at every stage of the development lifecycle. Where most tools wait for a human to trigger them, Checksum runs autonomously in the background, generating tests, executing them, and repairing failures without manual intervention. Seventy percent of test failures are resolved automatically through real-time auto-recovery.
The platform covers every layer: end-to-end UI flows via Playwright, API endpoint chains, and targeted CI tests scoped to exactly what changed in a PR. All tests land as real code in your repository and are delivered as standard Playwright, owned by your team.
Checksum is fine-tuned on 1.5+ million test runs and integrates natively with Cursor, Claude Code, and 100+ AI coding agents. Type /checksum and your coding agent's output gets tested before it ever reaches review. Generation and healing happen on Checksum's cloud infrastructure which means no LLM tokens consumed, no local resources required.
The result: test suites that stay green as the product evolves, fewer regressions reaching production, and release confidence that scales alongside AI output.

Devin Desktop is an AI-native software development platform that serves as a central command center for managing coding agents, development workflows, and code execution. The platform combines a professional-grade IDE with agent orchestration capabilities, enabling developers to plan tasks, delegate work, review outputs, and collaborate with AI agents from a single interface. Developers can run local and cloud-based agents simultaneously, allowing multiple coding tasks to progress in parallel while maintaining shared context across projects. The platform includes features such as Spaces for shared worktrees, Fast Context for rapid codebase understanding, Supercomplete for predictive coding assistance, and comprehensive code review capabilities. Devin Desktop supports the Agent Client Protocol (ACP), enabling interoperability with different AI models and agent frameworks. The platform integrates with popular developer tools, including GitHub, Slack, Notion, Linear, Stripe, Datadog, Atlassian, and various language servers. Developers can inspect every change made by agents through built-in debugging, tracing, and review tools to ensure code quality and reliability. The platform is designed to streamline both individual and team-based software development workflows while reducing context switching. Devin Desktop enables engineering teams to increase development velocity by combining human oversight with autonomous AI execution.

GSD Pi
GSD Pi serves as a local-first coding assistant designed to facilitate the planning, execution, validation, and tracking of project tasks through the command line. This tool integrates a terminal agent with various project workflow utilities, Git automation aware of worktrees, local project memory management, model routing capabilities, and optional user interface integrations, enabling projects to transition smoothly from conception to thorough review with minimal manual effort. At its core, GSD Pi operates on an execution loop that ensures AI-assisted engineering remains transparent: it transforms ambiguous intentions into clear scopes, formulates sustainable action plans with appropriate context, carries out tasks in organized environments, validates outcomes with supporting evidence, and finalizes work with accurate commits and dependable transitions. Users can initiate guided or rapid coding sessions directly from the shell, segment their projects into milestones, slices, and tasks, while leveraging the auto mode to orchestrate the planning, implementation, verification, and progression of their work. Additionally, GSD Pi retains a comprehensive repository of requirements, decisions made, runtime observations, generated plans, summaries, and validation evidence, which collectively enhance project continuity and accountability. Through this consolidation of features, GSD Pi empowers developers to maintain a streamlined workflow and achieve their project goals efficiently.

GSD 2
GSD 2 is a process-oriented framework for using AI agents in software development workflows. It is designed to help developers and teams turn AI-assisted coding from one-off prompts into a more organized system of planning, execution, and validation. The framework emphasizes the importance of clear specifications, shared context, review steps, and structured artifacts that guide how agents complete work. By creating a stronger process around AI coding, GSD 2 helps teams reduce confusion, improve handoffs, and maintain alignment between requirements and implementation. It supports the idea that successful AI development requires more than a powerful model; it also needs governance, feedback, and repeatable workflows. Developers can use GSD 2 to coordinate tasks, capture decisions, and review outputs before they become part of a production codebase. The framework is useful for managing the risks of AI-generated work, including specification drift, excessive trust in generated artifacts, and weak validation practices. It encourages human review as a core part of the development loop rather than treating AI output as automatically correct. GSD 2 helps teams use AI coding agents with more confidence, consistency, and engineering discipline.
