Cursor is incredibly good harness.

Opus is also not Oputhetic anymore

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.

Startups can begin with resources they can reasonably manage. A harmful mindset treats startups like they must follow a predetermined path, like attending college and securing a job.

Canva and Airbnb, both successful unicorn startups, initially bootstrapped their businesses before receiving external investments. Bootstrapping involves relying on self-generated funds and resources and offers advantages like maintaining full ownership, flexible decision-making, and simpler operations. However, it also has disadvantages like constant cash flow pressure, limited growth potential, and the inability to purchase resources with money.

While bootstrapping is more common in the US, it was historically less popular in Korea, where startups typically relied on external investments. After the dot-com bubble in 2000, Korean founders had to rely on personal savings or loans to start their businesses. The smartphone boom in the 2010s and government support led to a growth in Korea's startup ecosystem and a significant increase in venture capital investment. However, the rapid increase in funding and support may have resulted from a need for more understanding of Silicon Valley's organic development.

Korean startups often perceive that they must receive seed funding from accelerators, angel investors, or venture capital firms to succeed. This mindset can lead to a shock when entrepreneurs face increased risk and personal investment in their businesses. In addition, venture capital firms may push startups to grow faster than necessary, given their fund structures and the competitive nature of the industry. Recent news about the Korean startup industry has been negative, but focusing on revenue and cash flow is a normal part of running a business.
