flowise - low-code llm app builder (sunset)
About Flowise
Open-source drag-and-drop tool for building LLM flows and AI agents using LangChain and LlamaIndex nodes. Now sunset: the team announced in July 2026 it is winding down, the repository is archived read-only on GitHub, and official support ended 31 August 2026. The Apache 2.0 code can still be forked and self-hosted, but treat it as frozen software with no security patches coming.

Similar Tools to Flowise
Dify
Visual platform for building LLM-powered applications, RAG pipelines, chatbots, agents, and workflows; without deep ML expertise. Self-hostable or cloud, with 154,000+ GitHub stars.
DeepSeek Harness
MIT-licensed agent harness from DeepSeek AI, built on the idea that everything is a plugin: models, tools, skills, sessions, sandboxes, storage, loops, scheduling and the UI can each be swapped in configuration without touching the source. Start it with one command and it opens a local Web UI at 127.0.0.1:3080, with an append-only trajectory log you can resume, fork, search and replay. Read the trade-off before installing: DeepSeek calls it a developer preview, warns there will be compatibility-breaking changes, and states plainly that it has had no security audit and must not be treated as production-ready.
OmniRoute
Self-hosted, MIT-licensed AI gateway that puts one OpenAI-compatible endpoint in front of a large multi-provider model catalog. Point Claude Code, Codex, Cursor, Cline, or Copilot at localhost:20128/v1 and it auto-falls back to the next provider when a quota runs out, stacks free tiers, and compresses tokens. Local-first: keys and history stay in SQLite on your machine, no telemetry, no account. Note the trade-offs: provider counts drift between official pages, and draining stacked free tiers can conflict with some upstream providers' terms.
OpenClaw
Free, open-source personal AI assistant by Peter Steinberger that runs on your machine and performs real tasks autonomously. Talk to it from WhatsApp, Telegram, iMessage, Discord, Slack, or Signal. One-liner install, persistent local memory, ClawHub skills marketplace, sandbox or full system access, and support for Claude, OpenAI, DeepSeek, Qwen, or local LLMs via Ollama. 247K GitHub stars by March 2026; Steinberger joined OpenAI on February 14, 2026 with a non-profit foundation taking project stewardship.
Continue.dev
Open-source CLI tool for Continuous AI that runs async agents on pull requests to enforce team rules, catch issues, and accelerate software shipping.
OpenHands
Open-source AI software engineering agent (formerly OpenDevin) that browses the web, writes and executes code, runs bash commands, and resolves GitHub issues autonomously. Backed by All Hands AI and supported by 55k+ GitHub stars.
