LibreChat vs Proofly: Features, Pricing & Which Is Better (2026)
A side-by-side comparison of LibreChat and Proofly — features, pricing, and ideal use cases — to help you decide which AI tool fits your workflow.
LibreChat
LibreChat
An open-source, self-hostable AI chat platform that unifies every major model provider, agents, MCP tools, and code execution in one interface.
Key features
- Universal Model Switching: Select between Anthropic, OpenAI, Azure OpenAI, Google, Vertex AI, AWS Bedrock, Mistral, DeepSeek, Groq, Cohere, OpenRouter, Perplexity and any OpenAI-compatible custom endpoint from one chat, including local providers like Ollama and Apple MLX, without a proxy.
- No-Code Agents and Marketplace: Build specialized assistants with file handling, tools, and API actions, share them with specific users or groups, and discover community-built agents in an in-app marketplace.
- Skills and Subagents: Package reusable SKILL.md instruction bundles for manual, automatic, or always-on workflows, and delegate focused work to isolated child agent runs with their own context windows.
- Sandboxed Code Interpreter: Execute Python, Node.js, Go, C/C++, Java, PHP, Rust, and Fortran in a fully isolated environment with direct file upload, processing, and download and no data leaving the sandbox.
- Model Context Protocol Support: Connect agents to any MCP server for external tools and services, with OAuth-backed MCP sessions for controlled access.
- Generative UI Artifacts: Render React components, HTML, and Mermaid diagrams inline in chat, open them fullscreen, and export diagrams as SVG or PNG.
- Web Search with Reranking: Give any model live internet access by combining search providers, content scrapers, and result rerankers, including configurable Jina reranking endpoints.
- Enterprise Auth and Observability: Secure multi-user deployments with OAuth, SAML, LDAP SSO and two-factor auth, role and agent access controls, tenant isolation, and correlated log export through OpenTelemetry and Langfuse.
Best for
- Private Team ChatGPT: Self-hosting a shared AI workspace so conversations, files, and API keys stay inside an organization's own infrastructure.
- Multi-Provider Cost Control: Routing routine prompts to cheaper or local models and heavy reasoning to frontier models from a single interface, without separate subscriptions.
- Internal Agent Building: Creating no-code agents connected to company tools over MCP and sharing them with specific departments through role-based access.
- Data Analysis and Scripting: Running analysis, transformations, and one-off scripts through the sandboxed Code Interpreter with uploaded files, then downloading results.
- Research with Live Sources: Combining web search, reranking, and file search so models answer from current information rather than training data alone.
- Regulated Deployments: Running AI chat in environments that require SSO, audit logging, tenant isolation, and on-premise or private-cloud hosting.
