About

Twinbay is a hosted API simulation platform for developers testing AI agents and applications that call third-party services. Its stateful API twins can return configurable responses and model conditions such as payment declines, rate limits, expired credentials, email bounces, and paginated results. Teams direct compatible SDK requests to a twin, create isolated environments for test runs, inspect request logs, and use the environments in development or CI. The catalog includes twins for services such as GitHub, HubSpot, Plaid, Resend, Klaviyo, Linear, NetSuite, and QuickBooks. Twinbay offers a free plan with limits on twin usage and environment duration, pay-as-you-go twin-hour billing, and an Enterprise option. It is designed for engineers who need repeatable tests of agent behavior without relying on live production accounts or shared provider sandboxes.

About

Viven creates “Digital Twins” for employees by building personalized language models trained on a person’s actual work, emails, meetings, documents, and chat threads, so that their twin thinks, writes, and acts like them. The twin serves as an always-on assistant; it recalls critical context, prepares individuals before meetings, nudges teams when things are stuck, drafts follow-ups, and allows colleagues to ask it questions directly so the work can progress without the original person being present. Enterprise-grade deployment options support SaaS, private VPC, or on-premises environments, with fine-grained role-based access controls, full audit trails, and strong data governance built in. Viven integrates with tools like Gmail, Slack, Microsoft Teams, Outlook, Google Drive, OneDrive, Jira, Salesforce, and many others, so that the twin has a complete view of your working context.
