Simple scraper is the easiest way to scrape the web โ turn any website into an API in seconds and use ready-made scraping recipes to scrape popular sites with ease.
AgentShield is a cost observability platform for AI agents. Teams deploy LangChain, CrewAI, AutoGen, and LlamaIndex agents in production with zero visibility on what they actually cost. One agent loops overnight and a $1.50/day baseline becomes $150 before anyone notices. AgentShield fixes this with three modules: Monitor tracks costs in real time per agent with anomaly detection, budget caps, and a kill switch. Replay provides a step-by-step visual timeline of every session for fast debugging. Protect adds configurable guardrails, automatic PII redaction, and compliance-ready audit logs. Setup takes one line of code with the Python SDK.

AgentShield.one's answer:
Built by a solo founder as part of a challenge to ship 6 SaaS products in 6 months. AgentShield is tool number 1. The idea came from watching developers in the build-in-public community share stories about AI agents looping overnight and generating unexpected bills. The entire product was built in 5 days across 7 sprints with public kill criteria: less than $200 MRR at 12 weeks means killing the product and moving on.
AgentShield.one's answer:
LangSmith and Langfuse focus on tracing and prompt engineering. Helicone focuses on API logging. AgentShield is the only tool that combines real-time cost monitoring with anomaly detection, session replay, and production guardrails like PII redaction and budget caps with kill switch. It also supports LangChain, CrewAI, AutoGen, and LlamaIndex out of the box with a single Python decorator.
AgentShield.one's answer:
AgentShield combines cost tracking, session replay, and guardrails in one platform specifically built for AI agents. Most observability tools focus on infrastructure metrics, not per-agent cost breakdowns. AgentShield lets you see exactly what each agent costs per task, replay every step of a session for debugging, and set budget caps with an automatic kill switch. Setup takes one line of code.
AgentShield.one's answer:
Teams and solo developers running AI agents in production who need visibility on costs and behavior. This includes startups with 3-30 developers deploying LLM-based agents, AI agencies managing agents for multiple clients, and indie hackers building AI products who want to avoid surprise API bills.

Data extraction: https://simplescraper.io A project that I launched on HN that became a business. Simplescraper rode the no-code wave of a few years back ('instant structured data without parsing html'). Now working on increasing the surface area for AI agents: MCP support, screenshots API, and (experimentally) x402^ ^ https://simplescraper.io/blog/x402-payment-protocol/. - Source: Hacker News / 5 months ago
1. Clicking the box programmatically โ possible but inconsistent 2. Outsourcing the task to one of the many CAPTCHA-solving services (2Captcha etc) โ better 3. Using a pool of reliable IP addresses so you don't encounter checkboxes or turnstiles โ best I run a web scraping startup (https://simplescraper.io) and this is usually the approach.

Making my data extraction Saas (https://simplescraper.io) more LLM friendly. Markdown extraction, improved Google search, workflows - search for this terms, visit the first N links, summarize etc. Big demand for (or rather, expectation of) this lately. - Source: Hacker News / almost 2 years ago
Things are much easier for one-person startups these daysโit's a gift. I remember building a todo app as my first SaaS project, and choosing something called Stormpath for authentication. It subsequently shut down, forcing me to do a last-minute migration from a hostel in Japan using Nitrous Cloud IDE (which also shut down).
