Parlant

Open source · OSI-approvedStatus: unknown

A control layer for customer-facing AI agents

Parlant addresses the problem that stops most support agents from shipping: a model that is helpful ninety-five percent of the time is not safe to put in front of customers. It manages behaviour through explicit, context-matched guidelines rather than one long prompt.

Each response can be traced back to the guidelines that produced it, which is what makes the behaviour auditable rather than merely observed.

Decisive facts

Guidelines matched to conversational context rather than one prompt
Per-response traces showing which rules applied
Tool calling gated by the same guideline system
Consistent behaviour across long conversations
Self-hostable server with client SDKs

Dify is where a prompt experiment becomes something a team can operate. Workflows are assembled on a canvas, datasets are indexed and versioned, and every deployment gets an API endpoint with logging and cost tracking attached.

LicenseBSD-3-Clause

Open WebUI is the front end that turns a local inference server into something a household or a team can actually use. It handles accounts, conversation history, document retrieval, and model switching, and speaks to both local runtimes and hosted APIs.

Autonomous agents that complete real engineering tasks

LicenseMIT

OpenHands runs agents that plan and execute multi-step engineering work: reading a repository, editing files, running tests, and iterating until a task is done. Each agent works inside a sandboxed runtime rather than on the host machine.

LicenseAGPL-3.0

Firecrawl handles the unglamorous part of feeding the web to a language model: rendering JavaScript, following pagination, stripping navigation and cookie banners, and returning markdown or structured JSON that a model can actually use.

LangflowAIOpen

Drag-and-drop builder for agents and RAG pipelines

LicenseMIT

Langflow turns pipeline construction into a graph you can see. Components are Python underneath, so a flow that outgrows the canvas can be exported and run as code rather than rebuilt.

Browser UseAIOpen

Let AI agents drive a real browser

LicenseMIT

Browser Use gives an agent a real browser rather than an HTTP client. It handles the translation between a model's intent and DOM actions, keeps a structured representation of the page in context, and recovers from the usual navigation failures.
