SurveyJS is a set of four open-source JavaScript libraries that offer the benefits of a tailor-made in-house survey application, while considerably reducing the time and resources needed to deploy the system. These libraries are independent of specific server code or database requirements and seamlessly integrate with popular JavaScript frameworks, including React, Angular, Vue.js, jQuery, Knockout, and more. They are designed to communicate with any server that can handle JSON requests, ensuring compatibility with various server architectures and databases. The product family is composed of: - An open-source MIT-licensed rendering library that renders dynamic JSON-based forms in your web application, and collects responses. - A self-hosted drag & drop form builder that features an integrated CSS-based theme editor and a GUI for conditional rules. It automatically generates JSON definitions (schemas) of your forms in real time. - PDF Generator, a library that renders SurveyJS surveys and forms as PDF files in a browser; - The Dashboard library that allows you to simplify survey data analysis with interactive and customizable charts and tables.

ContractSafe is AI-enabled contract management software that actually does what it promises, without the six-month implementation, per-seat charges, or admin overhead that makes most CLM tools their own kind of problem. If you've been through that cycle before (a tool that takes months to deploy, requires a dedicated admin, hides pricing behind a sales call, and still leaves contracts expiring without warning), ContractSafe is the way out. Search is Google-fast across every contract and attachment, including full OCR on scanned PDFs. The AI assistant automatically extracts key metadata, categorizes contracts by type, and answers plain-language questions about contract content. Smart Search understands your intent rather than requiring exact keywords. None of it needs configuration or a dedicated admin. It works out of the box. Pricing is published publicly. No "contact sales for a quote," no per-seat charges that penalize you for adding users, no implementation fees. Every plan includes unlimited users, automated renewal and key-date alerts, a dedicated Customer Success Manager, and free onboarding assistance. Higher-tier plans add approval workflows, redlining, and built-in e-signature. Security: hosted on AWS, SOC 2 Type II and ISO 27001 certified, HIPAA and GDPR compliant, with data residency options across the US, Canada, EU, and Australia. Most teams are fully operational within hours of signing up. Free trial, no credit card required.
