- 1
Respect All Members
Treat others how you'd like to be treated, and assume good intent. This is a space for collective optimism, not harsh critique. Constructive feedback is welcome; personal attacks, harassment, and disrespectful behavior are not. Repeat violations will lead to a ban.

No solicitation or self-promotion
This community is designed for developers to share their work, ideas, and learnings. It is not meant for lead generation by vendors or recruiters, nor is it a place for competitors to advertise their products or services. Any vendors, recruiters, or competitors soliciting members will be permanently banned from the community.

Keep posts about LangChain
Post about building with LangChain, LangGraph, LangSmith, or Deep Agents: projects, questions, and things you've learned. Irrelevant content will be removed. This subreddit is not for product support. For bugs or help with your setup, please use the LangChain Forum at forum.langchain.com instead of posting in this subreddit.
What to post in r/LangChain
What fits the room, and what gets removed.
Works well
- A detailed breakdown of a project you built using LangChain, focusing on the technical challenges you overcame.
- A specific technical question about implementing a certain pattern in LangGraph.
- Sharing a key learning or insight you gained while using LangSmith to improve an agent's performance.
- A post detailing how you controlled or governed intelligence using the open agent engineering ecosystem.
Avoid

- Asking for product support or help with your setup, because the rules state you must use the LangChain Forum instead.
- Posting content that is not directly about building with LangChain, LangGraph, LangSmith, or Deep Agents, which violates “Keep posts about LangChain”.
- Engaging in personal attacks or disrespectful behavior, as this violates “Respect All Members”.

What r/LangChain Is For
This community is for people who want to build with LangChain, LangGraph, LangSmith, or Deep Agents. It is a space for developers to share their work, ideas, and things they have learned about this open agent engineering ecosystem, which enables every company to own their intelligence.
Rules That Matter Before Posting
The most important rules for anyone looking to post are “No solicitation or self-promotion”, “Keep posts about LangChain”, and “Respect All Members”. These three rules define what is acceptable content and behavior in the community.
What To Post
A good post here shows a specific project you built using LangChain, or it asks a technical question about how to implement a feature in LangGraph. You can also share a key learning or insight you gained while using LangSmith. The goal is to contribute to the collective optimism of the space by sharing your journey as a developer.
What To Avoid
You must avoid trying to advertise your product or services, as this is banned under “No solicitation or self-promotion”. You should also avoid posting about product bugs or asking for setup help, because the rules direct you to the official LangChain Forum for those kinds of issues. Finally, avoid posting irrelevant content, which will be removed under “Keep posts about LangChain”.
A note from Anthony
The rules here are very strict about keeping the focus purely technical. It is clear that the moderators want genuine developer conversations about building things, not sales pitches. The emphasis is on shared learning within the open agent engineering ecosystem.
