what AI can build

Send one prompt to selected models through OpenRouter, stream the replies into a side-by-side grid, and save the thread locally.

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.

The prompt was editor-reviewed; no completed build is recorded.

The honest tradeoff

why people still pay

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.

what you lose

the prompt

Curated prompt
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.

questions

Can AI replace Admix?

Possibly for a narrower core workflow, but this catalog judgment is not a verified build. Expected gaps include: Admix's bundled access to many providers under one subscription, A maintained model catalog and provider routing. Validate the prompt against your own acceptance criteria before committing.

How much does Admix cost?

Admix is listed at about $10/month (Starter, checked 2026-08-03), or $120 per year. This is a pricing reference, not evidence of a completed replacement or realized savings.

What do I lose by replacing Admix?

Honestly: Admix's bundled access to many providers under one subscription; A maintained model catalog and provider routing; Cross-device sync and account history; Built-in image, search, and document workflows; Usage limits, billing, and support handled for you. If any of those are load-bearing for you, keep paying.

Is there an open-source alternative to Admix?

Yes — Open WebUI (Open-source self-hosted chat interface for local and hosted models.), LibreChat (Open-source multi-model AI chat platform for self-hosting API-based assistants.). Using prior art is also a valid exit; the prompt is for when you want it exactly your way.
