As recorded at collection: Free access to AI models when you sign up for Langdock

Langdock is a service run by an enterprise AI company based in Berlin. It is a Y Combinator participant and has received $3.5 million in funding. Users report that a free sign-up provides access to Claude Opus 4.8, GPT 5.5, GPT Image 2, and FLUX2 [pro], that the models provided are the real models rather than imitations, and that the usage limits are generous.

Sign up at langdock.com with a temporary email address or an email address on a domain you own. Since no SMS verification is sent, you can enter any number in the phone number field. After signing up, you need to manually enable the model you want to use in Settings; Opus 4.8 is turned off by default. You can check your usage and remaining limit on the same screen, and you're also advised to turn on Overusage. Additional setup is required to connect AI so it can read a specific folder on your computer. First, install NodeJS and run `winget install ngrok.ngrok` in PowerShell. Sign up for ngrok and register the token you receive with the `ngrok config add-authtoken 내토큰` command. Open PowerShell in the folder you want to share, then run `npm install @modelcontextprotocol/server-filesystem` and `npx -y mcp-proxy --port 3000 -- cmd.exe /c npx -y @modelcontextprotocol/server-filesystem "폴더경로"` in order. When 'starting server on port 3000' appears, leave the window open. In Langdock, select Add Integration → Start From Scratch → Connect Remote MCP. In a new PowerShell window, run `ngrok http 3000`, then enter the address shown on the Forwarding line with `/mcp` appended to the end. Finally, type `@secure-filesystem-server` in the input box and provide the address and folder path. If it doesn't connect, change the end of the address to `/sse` and also provide the API key created in the ngrok dashboard (an authentication string required to use the service).

There is a limit on how much you can enter at one time. Users must decide whether this method complies with the terms of service and are responsible for any account, data, or security issues.
