Sharing a category with Flowise is what puts a product on this page at all. These 18 developer tools are the closest of the ones that do, ordered by how much of Flowise’s categories and tags each one covers and how closely its own description reads like Flowise’s — that is an ordering, not a verdict. We have not tested any of them, and there is no score on this page.

Workflow automation with code-level escape hatches
n8n is a workflow automation platform where nodes connect apps, APIs and AI models on a visual canvas, with the option to drop into JavaScript or Python for anything the nodes do not cover.
Build and ship LLM apps on one canvas
Dify combines prompt orchestration, RAG pipelines, agent tools and observability so a team can go from prototype to a deployed LLM application without stitching several products together.
The open-source workspace for your agents
Agenta is an open-source workspace that allows you to build, test, and share AI agents through chat. It features tools for human-in-the-loop approvals, version control for prompts and skills, run tracing, and team collab…
Chroma is a lightweight vector database that runs embedded in a Python or JavaScript process for prototyping and scales up as a server or hosted service for production.
The open-source agent operating system built in Rust
OpenFang is an open-source agent operating system that bundles autonomous hands, pre-built agents, tools, security systems, memory, and channel adapters into a single binary.
The open source LLM router for AI agents
Manifest is an open source LLM gateway that routes requests to various providers, fixes broken requests on the fly, and offers observability tools for AI agents.
Open-source vector database with hybrid search
Weaviate stores objects alongside their vector embeddings and supports hybrid keyword and semantic search, with modules that generate embeddings or call language models at query time.
Framework and platform for building LLM agents
LangChain provides open-source libraries for composing language model calls, tools, retrieval and agent loops, in Python and TypeScript.
Run open language models locally with one command
Ollama packages open models so they can be pulled and run on a laptop or server with a single command, exposing a local API that many tools already speak.
No-code platform to build AI agents and applications
LLMStack is an open-source platform that allows users to build generative AI applications, chatbots, and agents using their own data.
Sovereign agentic systems and open-source runtime
Ability.ai is an applied AI lab providing sovereign agentic systems built on Trinity, an open-source production runtime, and Cornelius, a self-improving cognitive core.
The open platform for cloud coding agents
OpenHands is an open-source, model-agnostic platform designed to run autonomous coding agents for software engineering tasks.
Orkas is an open-source, local-first application that lets you manage a team of specialist AI agents through chat.
AI agent server and framework for enterprises
Eidolon is an open-source framework and enterprise-grade deployment server designed for building and managing generative AI applications.
Connect LLMs to your documents and data
LlamaIndex is a framework for retrieval-augmented generation and document workflows, handling ingestion, chunking, indexing and querying over private data.
AI-powered SQL generation and data agent framework
Vanna is an open-source framework that uses AI for natural language database querying and agent development. It connects with multiple databases and language model providers to help users generate insights without writin…
Open source AI coding agent in IDE, CLI and Cloud
Kilo is an open-source AI coding agent available for VS Code, JetBrains, CLI, and cloud environments. It provides access to over 500 models with support for custom API keys and local models, featuring specialized modes f…
Open-source BI anyone on the team can query
Metabase lets non-technical users build questions and dashboards over a database through a visual query builder, while analysts can drop into SQL when needed.
This site holds four things about each of these products that are worth comparing before you open any of them, and none of them is an opinion. The pricing model above is the one recorded on the listing — a product marked Contact for pricing will cost you a sales call before it costs you anything else. The open-source column decides whether leaving later is a migration or an export. The shared categories and tags under each entry are how close the overlap with Flowise actually is: a tool covering all of Flowise’s categories is doing roughly the same job, one sharing a single category may only touch the same part of it — and a tool can be high on this page on the strength of its description alone, which means it describes the same work in the same words rather than that anybody checked it does that work well. Upvotes are votes cast here by people with accounts, and they say what this site’s readers picked, not what is best for you.
What we do not hold is a test. Nobody here has run these products side by side, so the last step is yours: open two of them and give each one the job you actually have.
