Why? Multi-tenant environments. First, we need to understand a few differences between environments:

• End-user UI
• Agent Runtime Environment
• LLM Server

So

• When you run Claude Code on your local MacBook, the first two are always local. The third is usually the Claude.ai server.
• When you ssh to a virtual private server (VPS) and install Claude Code there, the first two are your remote server. The third is still the Claude.ai server.
• When you run Claude RC on your virtual private server and code from your iPad using the Claude app, the end-user UI is on your iPad, the agent runtime environment is on your VPS, and the server is still Claude.ai.

Most people physically separate their tenancy, such as Claude Code, from their personal vs. work laptops. So in most cases, it's not a big deal.

But when you need multi-tenancy, it becomes super stressful. For example, say you have two different toolkits:

• personal toolkits (personal Notion, personal Sentry, personal Linear)
• workplace toolkits (company Notion, company Sentry, company Linear)

Most MCP auth states or code harnesses don't support profiles, so you can only log in to one.

So therefore... a natural evolution was to have both:

• a personal VPS with all personal toolkits set up
• a workplace VPS with all workspace toolkits set up

to physically isolate tenancies.

Now we've solved the multiple-profile issue, but the client's problems persist. Now let's get back to the environments:

• End-user UI
• Agent Runtime Environment
• LLM Server

All MCP auth or toolkit auth info should always be saved in the Agent Runtime Environment IMHO. However, a surprising number of harnesses tie them to the LLM server (such as Codex Apps or Claude.ai Plugins) or put them in the end-user UI (Claude Desktop or Codex Desktop).

Now the problem is:

• If the auth data is put on the LLM server, you cannot reuse LLM accounts across tenants
• If the auth data is put on the end-user UI, you cannot use the same app to access multi-tenants.

The only way to reliably isolate different auth information is thus:

• You ssh to a virtual private server (VPS) and run Claude Code there. Never use LLM server plugins.

Then

• End-user UI
• Agent Runtime Environment

are both isolated VPS, and

• LLM Server holds no information on the tenancy

This way, you can provide different toolkits, creating multiple dev environments.

• AutoBuilder

Kite is saying farewell

• From 2014 to 2021, Kite was a startup using AI to help developers write code. We have stopped working on Kite and are no longer supporting the Kite software
• First, we failed to deliver our vision of AI-assisted programming because we were 10+ years too early to market, i.e., the tech is not ready yet
• We failed to build a business because our product did not monetize, and it took too long to figure that out
• Then, we grew our user base. We executed very well here and expanded our user base to 500,000 monthly-active developers with almost zero marketing spend
• Then, our product failed to generate revenue. Our 500k developers would not pay to use it

Criticizing Computers

• Good hardware is masking terrible software
• All the bad code is piling up, and we don't know how to get rid of it
• Programs used to be pipeable. Now, GUIs are killing pipes
• Computers are telling me what to do, but I can't tell them what to do
• Software is not technology. It is ideology
• Computers are fast, but in the dumbest way possible
• No one knows what they're doing, and it's a civilizational problem
