# Alternatives to Langflow

> Source: https://theagentsindex.com/langflow/alternatives (current datasheets, evidence-ranked)

Candidates share the baseline category or are previously researched peers. Requirements, preserved strengths, explicit trade-offs and research coverage decide the order; paid tier does not.

## Shortlist

### 1. Agno

Python SDK, open-source AgentOS runtime and hosted control plane for building and operating agents.

**Research coverage:** 35/35 criteria

**Where it improves on Langflow:**
- [Whole-codebase work: partial — Repository-wide migrations are a named pattern, but the docs expect unresolved cases to be reported rather than fully landed.](https://docs.agno.com/use-cases/coding-agents)
- [In your editor: yes — `agno connect` writes MCP config for Claude Code, Claude Desktop, Codex and Cursor so those clients can run your agents.](https://docs.agno.com/cli/connect)
- [How it meters: yes — Priced per team seat and per live AgentOS connection; usage inside a connection is unmetered.](https://www.agno.com/pricing)

**Trade-offs against Langflow:**
- [In your pipeline: no — The enumerated serving surfaces are REST, MCP in Claude/ChatGPT and chat apps; no pull-request or CI surface appears.](https://www.agno.com/)
- [Open source: partial — SDK and AgentOS are Apache 2.0; the control plane is the commercial part and is not published as source.](https://www.agno.com/compare/agno-vs-langgraph)

### 2. LangChain

Open source agent frameworks plus LangSmith, the platform for tracing, evaluating and deploying agents.

**Research coverage:** 34/35 criteria

**Where it improves on Langflow:**
- [Whole-codebase work: partial — Engine reads a connected GitHub repository and opens pull requests; no vendor claim about carrying a migration across a whole repo.](https://docs.langchain.com/langsmith/engine-github)
- [Agent permissions: yes — Three approval modes: Manual asks before every gated action, Auto has a model classify routine ones, YOLO asks nothing.](https://docs.langchain.com/oss/deepagents/code/approval-modes)
- [In your editor: partial — LangSmith Studio is LangChain's own IDE for graphs, connected to a local Agent Server; no extension for third-party editors is documented and dcode is a terminal agent.](https://docs.langchain.com/langsmith/components)

**Trade-offs against Langflow:**
- [Self-hosted: partial — Platform self-hosting and hybrid are Enterprise-only; Developer and Plus are Cloud, while the open source packages run wherever you install them.](https://www.langchain.com/pricing)
- [Getting out: partial — Bulk trace export to S3 in Parquet is Enterprise-only for accounts opened after 3 August 2026; SDK trace queries stay open to all, and credit expiry is not stated.](https://docs.langchain.com/langsmith/data-export)

### 3. LangGraph

Open-source orchestration framework and runtime for stateful, long-running LLM agents, from LangChain.

**Research coverage:** 35/35 criteria

**Where it improves on Langflow:**
- [In your editor: partial — No editor extension is documented. The vendor's own development surface is LangSmith Studio, a browser IDE that attaches to a locally running Agent Server; your own editor is where you write the graph.](https://docs.langchain.com/langsmith/components)
- [In your pipeline: yes — The vendor publishes a CI/CD reference pipeline with a companion repository: tests and offline evals on a PR, then quality-gated preview and production deploys via the Control Plane API.](https://docs.langchain.com/langsmith/cicd-pipeline-example)
- [How it meters: yes — Two meters at once on the managed platform: a per-seat licence at 39 dollars per seat per month, plus consumption in LangChain Compute Units (1.50 dollars) and Storage Units (1.00 dollar). The library itself is free.](https://www.langchain.com/pricing)

**Trade-offs against Langflow:**
- [Admin controls: partial — Workspace RBAC and tag-based ABAC are Enterprise-only; other plans default every user to Admin. Gateway cost controls, rate limiting and PII redaction are checked on all three plans.](https://docs.langchain.com/langsmith/rbac)
- [Data residency: partial — US or EU choice inside LangChain's cloud from Plus upward; Enterprise adds hybrid and self-hosted with the data plane in your own VPC. The Developer column reads N/A.](https://www.langchain.com/pricing)
- [Getting out: partial — Bulk trace export to an S3-compatible bucket in Parquet is Enterprise-only for anyone who signed up after 3 August 2026. Usage is metered in arrears rather than prepaid, so there is no credit balance to expire.](https://docs.langchain.com/langsmith/data-export)

### 4. AgentsKit.js

TypeScript foundation for AI agents: runtime, tools, memory, RAG, model adapters and headless chat UI bindings.

**Research coverage:** 34/35 criteria

**Where it improves on Langflow:**
- [Whole-codebase work: partial — Multi-file edits and refactors are claimed for the coder persona over a filesystem scoped to one basePath; no repository indexing or repo-wide migration capability is documented.](https://www.agentskit.io/docs/agents/skills/coder)
- [Agent permissions: yes — Tool-level allow, deny and require policies plus per-tool quotas and confirmation-gated tools decide what runs unattended, though every constraint is opt-in code you write.](https://www.agentskit.io/docs/production/security/mandatory-sandbox)
- [In your editor: partial — The docs give three DIY patterns for running an agent inside VS Code or Raycast, but no editor extension is shipped and the LSP route is deferred.](https://www.agentskit.io/docs/production/embedded)

**Trade-offs against Langflow:**
- [In a browser: partial — Seven headless framework bindings give you a web chat surface to host yourself; the vendor runs no web app for the library, only sibling product sites.](https://www.agentskit.io/docs/ui)
- [Admin controls: partial — Constraints are real but expressed in code — validator chains, per-tool quotas and sandbox allow/deny lists — with no admin console or org-wide policy plane.](https://www.agentskit.io/docs/agents/guarantees)
- [Data residency: partial — Jurisdiction is yours to choose because nothing is hosted by the vendor, and the router can pin selection to a region, but no residency guarantee is published.](https://www.agentskit.io/docs/api/adapters/interfaces/RouterOptions)

### 5. Mastra

Open-source TypeScript framework for building AI agents, with a hosted platform for running and observing them.

**Research coverage:** 35/35 criteria

**Where it improves on Langflow:**
- [Whole-codebase work: partial — Agents you build get file tools over a mounted tree (grep and structural edits), but Mastra claims no repository-wide migration capability of its own.](https://mastra.ai/docs/sandbox/filesystem)
- [Agent permissions: yes — Tool approval can gate any tool call, per server or by predicate on tool name/arguments; approvals propagate up a subagent delegation chain.](https://mastra.ai/ai-agent-framework)
- [In your editor: partial — No IDE extension of its own; Mastra ships an MCP docs server and a skill that coding agents inside editors consume.](https://mastra.ai/reference/build-with-ai)

**Trade-offs against Langflow:**
- [Writes code: partial — Code mode has the model author a TypeScript function that orchestrates your tools, executed in a sandbox; it is a beta tool-use optimisation, not a code-authoring product.](https://mastra.ai/docs/agents/code-mode)
- [Admin controls: partial — RBAC restricts read/write/execute/delete per resource in Studio and on the API, but SSO and RBAC in production are Enterprise Edition features requiring a licence.](https://mastra.ai/docs/studio/auth)
- [Data residency: partial — Self-hosted Enterprise keeps traces, prompts and outputs inside your own VPC; for the hosted platform the vendor publishes no region or jurisdiction.](https://mastra.ai/pricing)

### 6. Pydantic AI

Typed Python agent framework: any model, any surface, with a harness for long-running coding and research agents.

**Research coverage:** 34/35 criteria

**Where it improves on Langflow:**
- [Whole-codebase work: partial — Repo-wide orientation and context management for long sessions are documented (RepoContext, compaction, a read-only explorer sub-agent), but no page claims a repository-wide migration as an outcome.](https://pydantic.dev/docs/ai/overview/)
- [In your editor: partial — An editor surface exists over the Agent Client Protocol for editors such as Zed, but it is shipped as experimental and the docs say it may be removed in any release without a deprecation period.](https://pydantic.dev/docs/ai/harness/acp/)
- [How it meters: yes — The framework itself meters nothing; you pay whichever model provider you configure, and the optional Gateway is free on your own keys or a percentage markup on its built-in providers.](https://pydantic.dev/ai-gateway)

**Trade-offs against Langflow:**
- [In your pipeline: no — The surface table enumerates code, terminal, web chat, your frontend, editors and voice; nothing acts on a pull request or in CI, and the roadmap line names messaging channels and API endpoints as what is still missing.](https://pydantic.dev/docs/ai/overview/interfaces/)
- [Admin controls: partial — Constraints are code, not a console: guardrail callables gate prompts, tool calls and outputs, alongside shell allowlists, tool approval and spend limits. Role-based control arrives only with Logfire Enterprise.](https://pydantic.dev/docs/ai/harness/guardrails/)
- [Data residency: partial — The library holds nothing, so residency is yours. If you send telemetry to Logfire, you choose a US or EU region at signup; regions are strictly separated and migration between them is not available.](https://pydantic.dev/docs/logfire/manage/data-regions/)
