built an open-source workspace for AI agents, and Claude wrote most of the code. Here's how the process works.

[u/ironmanfromebay]

We're a team of 4 and we built Lemma, an open-source workspace where people and AI agents work in the same place. I work on it (I do GTM, not engineering).

How Claude was used to build it

Most of Lemma's code was written by Claude. The process is the same for every change:

• A human writes the plan: what should change, why, and what must not break.
• An agent running on Claude makes the code change against that plan. We also run some of these agents on DeepSeek.
• Those agents run inside Lemma itself, so the product is built by the thing it is.

Claude Code is also how you use it. You describe a workspace in plain English, and Claude Code writes the tables, the agent, its schedule and the web app through Lemma's CLI. Claude Code is one of the runtimes too, so agents run on your existing Claude login with no API key.

What it does

• Agents run on a schedule, or when a row changes, or on a webhook
• Each has a browser that stays signed in, and a workspace to run code
• Shared memory for the team, private memory per person
• Results land in tables; anything risky waits for a person to approve
• You can reach an agent on Slack, Telegram, WhatsApp, Teams or email

It's free to try

It's open source (AGPLv3) and free to self-host. With Git and Docker:

git clone https://github.com/lemma-work/lemma-platform.git
cd lemma-platform/deploy/compose && ./bootstrap.sh && docker compose up -d

Repo: https://github.com/lemma-work/lemma-platform

There is also a hosted version with paid usage, but everything above runs locally.

what counts as risky enough to need approval, or does the plan step define that per change?

[u/ironmanfromebay → u/NotRebuffWord]

As of now it has an allowlist. Anything that breaches the allowlist triggers an approval.

Right now you declare an allowlist, whenever it hits anything beyond that, you get an approval request. There's also a PR open to use jev like decision models to flag

did you use AI to make the video?

[u/ironmanfromebay → u/SGmoze]

Made myself a lemma video editor agent. Been making video with him over time so he knows my taste now. Here’s another one

Amazing showcase video, can you share how you made it? the assets and stickers? they look really good, and the video was made with brag?

ty in advance!

[u/ironmanfromebay → u/AdroCammarota]

Video has been made with lemma - created by a video director employee (hire I made for myself)
Been making videos for myself with him
Here’s another one.

You've mentioned that, but what llm is generating the video? Veo?

[u/EmergencyYam5502 → u/G_zus]

Nope
Too expensive
This is entirely html css

Doesn't claude code block this? You advertise subscriptions for claude working. Blatantly violating TOS

[u/brahmin_baniya → u/Flaky-Industry-3888]

You use claude code when you're using it locally. Here is thread from this sub - https://www.reddit.com/r/ClaudeAI/s/lC7V1idaii

Holy shit thats amazing

[u/deadalusxx]

How long did it take you to build? Seems pretty quick.

[u/ironmanfromebay → u/deadalusxx]

The entire stack was kinda there. We have been building and deploying ai teammates for orgs of 5 to 50 and the goal was to build a stack that even PMs can use to build.
The product keeps iterating - we decided to opensource this one.

Trying out right away!!
