Requestly is a modern and powerful companion for API Development and Testing. It is an open-source tool purpose-built to speed up and simplify API development workflow for developers and QAs. It is a combination of API Client and HTTP Interceptor that helps create and share API Contracts, testing APIs, and easily mock and integrate them into web and mobile apps.
Notte provides a full-stack framework for building, deploying, and scaling web AI agents via a single API. It transforms the internet into an agent-friendly environment by mapping websites into structured, natural language descriptions, enabling agents to navigate and interact effectively.
Notte leads in open-source benchmarks for web agent performance. It achieved the highest self-reported success rate (86.2%) and LLM-verified completion (79%). Notte also demonstrated the fastest execution time (47 seconds per task) and an impressive 96.6% task reliability (percentage of tasks successfully completed at least once across multiple attempts).

Front-end developers, QAs, PMs, Digital Marketers
notte's answer:
Developers building LLM agents, automation workflows, or AI-native applications. Early adopters in infra, QA, RPA, and AI tooling who want to go beyond brittle web scraping and fragile automation toward agentic, semantic control of the internet.
Requestly's answer
Requestly is an open-source API development and testing tool that combines the capabilities of an API Client and HTTP Interceptor, making it a better alternative to Postman + Charles Proxy. It simplifies API mocking, request modification, and debugging with an intuitive no-code interface, enabling developers and QAs to test APIs efficiently.
notte's answer:
Notte turns the web into structured, semantic maps tailored for LLMs โ enabling perception, navigation, and action. Unlike traditional browser automation, Notte abstracts away fragile HTML into high-level actions and natural language descriptions, reducing hallucinations, tokens, and latency.
notte's answer:
Notte is built with Python and accessible via Python SDK or REST API. It performs deep DOM parsing and uses a semantic abstraction layer informed by graph-based reasoning โ though the graph itself isnโt fully materialised in code. The SDK exposes a clean interface for LLM integration.
notte's answer:
Notte is purpose-built for LLM agents. It doesnโt just click DOM elements โ it understands the intent behind them. That means faster, more reliable agents, no brittle scripts, and seamless integration via API or SDK. It replaces scraping + Playwright stacks with one clean abstraction layer.
notte's answer:
Notte was founded by Andrea and Lucas, two ML researchers who met at EPFL in 2019 and have been building together ever since. After working across top research labs, they saw a clear gap: existing browser automation tools werenโt built for LLMs. Notte is their response โ a framework that makes the web usable for agents through structured, semantic understanding. Itโs designed to bridge research and real-world execution.
