Loadster is a cloud-based load testing and synthetic monitoring platform for engineers who want to know how their applications behave under real traffic.
Tests run with three types of bots: Protocol Bots for HTTP testing, headless Browser Bots that render full pages and execute JavaScript in real Chrome browsers, and Playwright bots for when you want to use Playwright JS directly.
Loadster scripts can be recorded from Chrome or Firefox with the Loadster Recorder extension, edited in a built-in editor with variables, datasets, and shared includes, and then replayed from multiple cloud regions.
Each test run returns detailed page timings (TTFB, FCP, LCP, CLS, etc) alongside resource waterfalls, screenshots, and full traces you can step through in a self-hosted trace viewer. Tests scale from a handful of virtual users (bots) to hundreds of thousands across distributed cloud engines without you provisioning anything.
The same scripts can be set up as monitors that run on a schedule from chosen regions. Notification policies route incidents to email, SMS, voice, or integrations like Slack and PagerDuty. Projects, roles, and shared test history keep teams aligned on what passed, what failed, and what changed.
Pricing is usage-based via Loadster Fuel, with 50 free units on sign-up and no credit card to start.
Jsonify is an AI "data intern" in the cloud -- an intelligent AI agent that can automate data collection and maintenance tasks involving the web and documents. We automate the collection and maintenance of your entire web data pipeline, end-to-end. Jsonify visits websites, understands them in the same way a human does, navigates the website to find the data you want, extracts it, validates results, and synchronizes it somewhere useful for you โ all from our dashboard.
The no-code workflow builder lets you easily script varied tasks. For example: - "every day, go to each of these companies, navigate to the team page, find the LinkedIn of each team member, and save their technical lead to a Google Doc" - "every week, visit these 500,000 company websites, find their jobs page, and send the list of their jobs to Airtable" - "build a spreadsheet of the competitive landscape of AI data startups" - "monitor our competitors products and email me when something is cheaper than ours"
