Google Gemini alternatives: 8 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.
Un escritorio privado de IA para documentos y agentes; instálalo y luego elige modelos locales o el medidor de otro proveedor.
licenseMIT
runsyour machine or their cloud
installDesktop installer for macOS/Windows/Linux, or Docker for a self-hosted web instance
enginesLocal llama.cpp models plus Ollama, LM Studio, LocalAI and many cloud APIs including OpenAI, Anthropic, Gemini, Bedrock, Azure, OpenRouter and Mistral
dataDesktop data stays in the app's local storage; self-hosted data is stored in the mounted server storage and chosen vector database (LanceDB by default), while prompts sent to cloud models leave the machine
the catch vs Google GeminiIt cannot reproduce Gemini's first-party Gmail, Docs, Drive, Android, and Google Search integration, and it includes no Google AI Pro model quota.
setupThe installer is easy, but useful results still require downloading a local model or supplying a model-provider API key

Un conmutador de modelos de escritorio con asistentes, archivos, agentes y MCP; trae tus claves o haz sudar a tu laptop.
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 Google GeminiIt makes you supply each model and account yourself and cannot match Gemini's first-party integration across Google's apps and services.
setupThe app installs cleanly, but the first useful chat requires an API key or a separately installed local model server

Un asistente de escritorio con prioridad local con conectores en la nube y herramientas; tu RAM recibe la factura.
licenseApache-2.0

installDownload the macOS, Windows or Linux desktop installer
enginesBuilt-in local inference via llama.cpp/llama-server plus OpenAI-compatible APIs and connectors such as OpenAI, Anthropic, Gemini, Groq, Mistral and OpenRouter
dataThreads, assistants, settings and downloaded model files live in Jan's local data folder; only requests sent to configured cloud providers leave the machine
the catch vs Google GeminiIt can provide local or bring-your-own-model chat, but not Gemini's included frontier-model access or native Google ecosystem integration.
setupLocal use requires downloading a multi-gigabyte model and enough RAM; cloud use requires an API key

Un conmutador de modelos autoalojado con agentes, archivos y herramientas; software gratuito, facturas de modelos de pago si usas modelos de pago.
licenseMIT
runsyour server
installClone the repository and start the recommended Docker Compose stack
enginesOpenAI, Anthropic, Google Gemini/Vertex AI, Azure OpenAI, AWS Bedrock, Mistral, Groq, OpenRouter, DeepSeek and custom OpenAI-compatible endpoints, plus agents and MCP
dataConversations, users and configuration live in MongoDB; search indexes use Meilisearch, uploaded/RAG content uses bundled storage and a vector database; prompts sent to cloud models leave the host
the catch vs Google GeminiIt adds server administration and separate model bills while still lacking Gemini's native Gmail, Docs, Drive, Search, and Android integration.
setupDocker Compose brings several services, and the default MongoDB image does not run on Apple Silicon without changing the setup

Un espacio de trabajo multimodelo con prioridad local con archivos, búsqueda, código y personajes; la interfaz asume que disfrutas los botones.
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 Google GeminiIt supplies a multi-model interface but not Gemini's included model allowance or first-party integration across Google Search, Gmail, Docs, Drive, and Android.
setupThe free hosted app is immediate, but it does not include model usage: the user must bring provider API keys and understand provider billing

Un laboratorio de escritorio para modelos locales con chat, documentos y herramientas; gratis para siempre, pero tu hardware ahora es la nube.
licenseproprietary, free
runson your machine
installDownload the macOS, Windows or Linux desktop installer
enginesRuns GGUF models through llama.cpp and MLX models on Apple Silicon; downloads models from Hugging Face and exposes local OpenAI- and Anthropic-compatible APIs
dataChats, attached documents, presets and downloaded model weights stay in LM Studio's local application data; local chat and RAG can run fully offline
the catch vs Google GeminiIt is a local-model laboratory, so live web grounding, Google's frontier models, and tight integration with Google apps are the main losses.
setupThe installer is clean, but the user must choose and download a model large enough for the task and small enough for their RAM

Autoalojamiento con forma de ChatGPT con modelos, archivos, búsqueda y herramientas; el software es gratis, el rol de administrador es tuyo.
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 Google GeminiIt can imitate the chat surface, but it does not include Gemini usage or Google's first-party Search, Workspace, and Android integrations.
setupA non-expert must install Docker or a compatible Python environment, mount persistent storage correctly, and separately provide Ollama or an API endpoint

Un espacio de trabajo pulido para agentes y archivos; el autoalojamiento es gratis y la inferencia de frontera generalmente no lo es.
licenseLobeHub Community
runsyour machine or their cloud
installUse the hosted service, or self-host with Docker Compose or a supported cloud deployment template
enginesOpenAI-compatible providers plus OpenAI, Anthropic, Gemini, Bedrock, Azure, OpenRouter, Ollama and other local/cloud model endpoints
dataHosted data lives in LobeHub's cloud; self-hosted deployments use PostgreSQL for app data and S3-compatible object storage for files, with model prompts also sent to the configured provider
the catch vs Google GeminiIt offers a polished model workspace but not Gemini's bundled model capacity or first-party integration with Google's consumer and Workspace products.
setupSelf-hosting now means configuring Docker plus PostgreSQL, authentication and S3-compatible storage rather than launching a single stateless container

MstyThe desktop core is $0, but the terms limit it to private non-commercial use; paid work needs a license.

They pay for model access and Google-native placement, not because chat UIs are hard. If none of that applies to you, any pick above saves $239.88 a year.
Is there a free alternative to Google Gemini?
Yes: AnythingLLM, Cherry Studio, Jan and 5 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 Google Gemini?
Our verdict is NO TANTO. A chat UI is easy, but Gemini's model access, Google ecosystem integration, multimodality, storage tie-ins, and platform distribution are not solo-buildable. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/gemini.
