Svix
Svix
Webhooks require a lot more engineering time, resources and ongoing maintenance than you would first expect. Building a secure, reliable, and scalable webhook service is hard and time consuming. We built it so you can focus on what matters most, your business. Customer endpoints fail or hang more often than you think. You need automatic retries to ensure deliverability. You need to monitor the deliverability of your webhooks to different endpoints, disable failing ones and notify your customers. Webhooks come with a myriad of security implications, such as SSRF, replay attacks and unauthenticated webhook events. You would need to build a UI for your users to add and remove endpoints, inspect logs and get ongoing reports. Offer your users a great developer experience, including the ability to test, inspect and replay their webhooks.Starting Price: $490/month -

BrowsingBee is an AI-powered browser testing platform that transforms automated testing by enabling users to write tests in plain English while delivering resilience to UI changes through adaptive, self-healing test scripts. Through an intuitive interface, it generates robust tests that automatically adjust when elements change, logs each run via video recordings for precise debugging, and employs AI-driven analysis to proactively detect bugs before they reach production. It supports a range of testing needs, from regression and user-journey workflows (e.g., signup to purchase flows) to cross-browser compatibility across Chrome, Firefox, Safari, and Edge, as well as performance metrics like page load and API response times. Tests can be scheduled for 24/7 application monitoring, with smart notifications via Slack, email, or webhooks to alert teams of failures.Starting Price: $24.2 per month -
