Admix alternatives: 5 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
A desktop model cockpit with parallel answers, files, agents, and rather more settings than restraint.
licenseAGPL-3.0
runson your machine
installDownload the signed desktop installer for macOS, Windows or Linux
enginesOpenAI, Anthropic, Gemini and many other cloud APIs; Claude, Perplexity and Poe web integrations; local models through Ollama or LM Studio; OpenAI-compatible endpoints
dataChats, assistants and settings are stored in the desktop app's local profile; optional WebDAV backup/sync and cloud model calls copy relevant content to those services
the catch vs AdmixParallel answers work, but you must bring and manage every model endpoint yourself rather than getting Admix's focused, unified comparison service.
setupThe app installs cleanly, but the first useful chat requires an API key or a separately installed local model server

Same prompt, several models, side by side; bring API keys or make local models do the arguing.
The exact compare-everyone desktop app; use API-backed bots, because scraped web connectors break whenever vendors sneeze.
licenseApache-2.0
runson your machine
installDownload the Windows installer, macOS DMG/Homebrew package, or Linux DEB/AppImage from GitHub Releases
enginesRuns many providers concurrently, including API-backed OpenAI, Claude, Gemini, Groq, Cohere, xAI and web-connected bots; each bot needs its own account or token
dataChat history, settings and login data stay in the local application profile; anonymous usage telemetry excludes prompt and response contents
the catch vs AdmixIt is the closest functional match, but its web-account connectors are brittle and every provider still needs a separate working login or API credential.
setupYou must bring working accounts or API tokens, and its reverse-engineered web connectors frequently break when vendors change their sites
facts verified 2026-08-14
One prompt fans out across models and Beam can merge the answers; free software, paid API keys if you chase frontier models.
licenseMIT
runsyour machine or their cloud
installUse the hosted web app with your API keys, or self-host with Docker/Vercel
enginesOpenAI, Anthropic, Gemini, Azure, Bedrock, DeepSeek, Groq, Mistral, OpenRouter, Perplexity, Together, xAI, Ollama, LocalAI, LM Studio and OpenAI-compatible endpoints
dataThe open app stores chats and settings locally in the browser by default; hosted Pro adds synced cloud storage, and model requests go to whichever provider the user configures
the catch vs AdmixIt can fan one prompt across models, but you must provision and bill each provider separately and its interface is less focused on clean answer comparison than Admix.
setupThe free hosted app is immediate, but it does not include model usage: the user must bring provider API keys and understand provider billing
facts verified 2026-08-14
Run several models in parallel columns and merge the result; free to run, source-available rather than open source.
licenseOpen WebUI
runsyour server
installRun the official Docker image, install the Python package, or deploy with Kubernetes
enginesOllama and any OpenAI-compatible API, including LM Studio, vLLM, Groq, Mistral and OpenRouter; additional speech, image and search providers
dataBy default, chats and account data live in a local SQLite webui.db, uploads in a data/uploads directory and embeddings in the configured vector store; PostgreSQL and object storage are optional
the catch vs AdmixParallel chats work, but the self-hosted interface is less focused on clean side-by-side evaluation and still leaves provider setup and billing to you.
setupA non-expert must install Docker or a compatible Python environment, mount persistent storage correctly, and separately provide Ollama or an API endpoint

MstyThe desktop core is $0, but the terms limit it to private non-commercial use; paid work needs a license.
LibreChatA polished multi-provider chat, but it does not send one prompt to several models side by side.

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. If none of that applies to you, any pick above saves $120 a year.
Is there a free alternative to Admix?
Yes: Cherry Studio, Cherry Studio, ChatALL and 2 more. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Admix?
Our verdict is KINDA. 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. If you'd rather build, the exact one-shot prompt is free at vibecodeit.com/admix.
