Bolt.new
- +Full dev environment runs in the browser via WebContainers, with the AI controlling filesystem, terminal, and server
- +Generates true full-stack apps (not just UI) and can deploy via Bolt Cloud
- +No local setup; fast for prototyping and iterating by chatting
- -Token-based usage cost can rise quickly on complex or long-running builds
- -Output needs human review and iteration; it is not a hands-off autonomous engineer
Tabby
- +True self-hosted/on-prem, no cloud or database dependency; runs on consumer GPUs for air-gapped or regulated environments
- +Open source (Apache 2.0 core), model-agnostic, with an OpenAI-compatible API
- +Actively maintained with broad IDE coverage, repo-aware completion, and an Answer Engine
- -Capability ceiling versus cloud incumbents: fundamentally completion, chat, and retrieval
- -Agentic workflows and MCP are roadmap or private preview, not generally available
Which should you choose?
Bolt.new is prompt, edit, and deploy full-stack web apps in the browser, best for consumers, developers, smb. Tabby is self-hosted, open-source ai coding assistant for privacy-conscious teams, best for developers, enterprise.
