Checksum.ai
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.

Description

Developers anticipate that your API will come equipped with a typesafe client library tailored to their programming language. With Stainless, you can provide well-crafted SDKs while concentrating on developing the API itself. High-quality SDKs enhance the integration process, promote wider feature utilization, facilitate quicker updates, and build confidence in your engineering standards. At Stainless, we strive to ensure that each SDK feels meticulously crafted by a specialist in the specific language, as if they had ample time to perfect it. Our libraries offer extensive types for features like autocomplete and hover documentation, as well as functionalities such as auto-pagination, auto-retry with backoff, seamless authentication, and much more. To get started with Stainless, all you need is your OpenAPI specification, and it doesn’t need to be flawless. We will generate an initial Stainless configuration file that standardizes naming conventions and outlines essential functionalities like pagination and authentication. You will receive ready-to-use SDKs in the programming languages your developers prefer, and you also have the option to tailor the Stainless configuration for more customized SDKs that truly reflect your brand. This flexibility ensures that your SDKs not only meet technical requirements but also align with your unique identity in the developer ecosystem.
