FlexiGPT is a local-first BYOK AI workspace for power users and teams who need repeatable LLM workflows with model choices, Agents, Workspaces, MCP servers, tools, Skills, and private local history across multiple providers.
- Power users, developers, writers, consultants, teams, and interface builders who use LLMs for repeatable work.
- I want to be in the driver's seat when using LLMs.
- I want to use LLMs as tools while staying in control of what I do and how I do it. Most systems seem to be designed to let their tooling and workflows drive the work.
- Writing the whole LLM setup down as plain, versionable files: models, prompts, Agents, MCP servers, Skills, files, and Workspace context along with built-in Go tools.
- Assembling every request from that setup, with its exact input inspectable before it is sent. Nothing gets injected behind your back.
- Controlling every action: you declare what runs automatically, what asks first, and what is never allowed. Pause automatic execution mid task, change input, resume as needed. Per tool, per Agent, per Workspace.
- Keeping a record of each run - input, output, and what it changed - so it can be reviewed, diffed, and repeated.
- Exposing all of it through one uniform interface, so any application can drive the same setup.
- Building use-case UIs on top of that interface, starting with chat.
- Download the latest release from GitHub Releases.

- macOS:
- Install the package. Detailed installation steps are in Installation.
- Launch FlexiGPT.
- Get an API key for a hosted provider, or start a local LLM server you control.
- Open Models and add the key alongside the matching provider/model setup.
- For local endpoints that require a non-empty key, add a harmless placeholder key for the local provider.
- In Models, enable a built-in provider/model or fork a provider for your endpoint.
- Open Chats.
- Choose a built-in Agent for a reusable starting setup, or choose a model directly.
- Attach files, folders, notes, PDFs, URLs, or code when the model needs source material.
- Optionally select a Workspace for recurring repository or folder context, or an already configured MCP server for connected tools, resources, or prompts.
- Send.
Good first workflows:
- Use a home screen workflow card such as Develop a Feature, Review Code, or Investigate a Bug.
- Attach only the relevant source material.
- For code changes, start with a repo path or changed files and let the Spec Driven Development Agent inspect, scope, implement, and verify the change.
- Review the prefilled opening text and adjust it for your task before sending.
- Export, edit, and import an Agent when you need a durable variation.
FlexiGPT does not bill you directly. Usage costs and limits come from the provider account behind the key you configure.
FlexiGPT does not proxy LLM calls through a FlexiGPT-hosted service. Requests go directly to the provider or endpoint you configure.
- Built-in support for OpenAI, Anthropic, Google Gemini, xAI, Mistral, Hugging Face, OpenRouter, and local/self-hosted runtimes such as LocalAI, LM Studio,
llama.cpp, Ollama, SGLang, and vLLM. - Custom endpoints across OpenAI Chat Completions, OpenAI Responses, Anthropic Messages, and Google GenerateContent-style APIs.
- Curated built-in providers and models so you can start quickly without manually defining endpoints or defaults first.
- Provider and model configuration is managed in Models, where local users can copy/fork a built-in provider, adjust the endpoint, headers, compatibility type, and model defaults, then use the forked provider in Chats.
- API keys are entered in Models and stored securely through the OS keyring, not in plain-text exported settings.
- One interface for chats, tabs, reusable Agents, Workspaces, MCP servers, models, attachments, tools, Skills, search, and exports.
- Build repeatable workflows by combining Agents, Workspaces, model choices, attachments, tools, Skills, and connected services.
- Skills can seed starter drafts, carry instruction-only behavior, or manage reusable workflow state.
- Switch providers or models as you iterate.
- Multi-tab conversations with local history search and resume flows.
- Export the current conversation as JSON.
- Agents can prepare a model choice, instructions, opening text, tools, Skills, and connected services without locking the chat.
- Workspaces provide reusable repository or folder context without reattaching the same project material.
- MCP servers can contribute selected tools, resources, resource templates, prompts, and instructions from configured local or remote services.
- Tools can be attached per conversation or per message and configured for manual review or auto-execution.
- Tool implementations are built-in Go tools. Custom HTTP tools are not supported.
- When an eligible auto-execute tool is called, FlexiGPT can run it and submit the result back to the model.
- Keep tools manual when you want tighter control over execution.
- Markdown rendering with syntax-highlighted code blocks.
- Mermaid diagram rendering with zoom and source or image export workflows.
- KaTeX math rendering.
- Citations, token usage, and per-message request/response details for inspection and debugging.
- Message-level controls for copying, inspection, and follow-up iteration.
- Local conversation storage and full-text search.
- File, folder, image, PDF, and URL attachments.
- Bundled offline docs shipped inside the app.
- Conversations, Agent Plugins, Agent files, Workspace setup, MCP server catalogs, and configuration are stored locally.
- Selected request context is sent to the provider or endpoint you choose when you send.
- Use your own provider accounts. FlexiGPT does not proxy or bill model usage.
- Develop bounded features and enhancements from local repo context with a spec, implementation steps, edits, and focused verification.
- Review code, diffs, and PRs for correctness, security, reliability, maintainability, and test gaps.
- Investigate bugs from logs, stack traces, failing outputs, source files, and config.
- Refactor code, design tests, implement tests, explore codebases, and review architecture with built-in software Agents.
- Use read-only Agents for review/investigation and manually review any built-in tool with write or other external side effects.
- Built-in Agents cover PRD/MRD writing, decision records, user feedback analysis, roadmap prioritization, delivery risk review, and stakeholder status updates.
- Technical-writing Agents cover docs audits, docs authoring, API reference, release notes, and troubleshooting guides.
