Try Every Integration Without an Account: Public Demo Credentials in All Five Packages
Every integration can now be tried without an account. The LangChain, LlamaIndex, Haystack, MCP and Laravel Scout packages all ship with the credentials of a public demo account, so the quickstart in each README runs on a fresh machine with nothing to sign up for and nothing to configure. An index preloaded with 300 news articles is there to search immediately, and you can create your own indexes on the account and push documents into them. Everything created on it is deleted after 3 days, the account is shared with everyone using it, and the limits are small and per index — 200 MB of bandwidth and 50 MB of disk — so it covers a demo and a proof of concept rather than an application.
