Should you build your own Admix?
Multi-model AI chat that compares answers side by side across providers
A local chat UI with side-by-side replies is a weekend project when it calls OpenRouter, but Admix's value depends on access to many hosted models, a current catalog, provider routing, and a maintained account and billing layer. You can reproduce the comparison workflow. You cannot reproduce the model access and service layer for a flat $10 subscription.

Build me a local multi-model comparison chat to replace Admix. Requirements:
- Node 22 + Express + better-sqlite3, a server-rendered shell with a little vanilla
JS for streaming; no frontend framework, no build step.
- One OpenRouter key in .env, kept server-side; the server proxies all model calls.
- A model picker fed from OpenRouter's /models endpoint; select up to four models.
- One prompt fans out to the selected models and streams each reply into a
side-by-side grid with model name, elapsed time, and token usage when reported;
a failed model shows its error in its own column without killing the others.
- Markdown rendering with fenced code blocks and a copy button per reply.
- Threads, prompts, model ids, replies, and timestamps in SQLite; full-text search
across saved threads; export a thread as Markdown.
- A running cost estimate per thread from OpenRouter's usage and pricing fields.
- Binds to localhost only. No accounts, no telemetry; prompts and replies leave the
machine only for OpenRouter, and the README says so.
- Out of scope: auth, billing, mobile apps, image generation, hosted sync, and
provider-specific tools like web search or file upload.
- README: setup, .env.example, and how to add a model id by hand if the catalog
fetch fails.The prompt opens pre-filled in your agent. Review it before running.
What would building your own look like?
Send one prompt to selected models through OpenRouter, stream the replies into a side-by-side grid, and save the thread locally.
What you will need
- Node 22
- OpenRouter API key in .env
- SQLite
- Provider and model IDs to compare
They pay for one bill and one interface instead of managing several provider accounts, API keys, model IDs, and usage limits. The comparison grid is easy to copy; keeping model access and the account, billing, and storage layer working is the service.
