Flows Ai
A type-safe, open-source TypeScript library for orchestrating multi-step AI workflows on top of the Vercel AI SDK.
If you already write TypeScript against the Vercel AI SDK and your pipelines are outgrowing hand-rolled async functions, Flows AI is the least invasive way to add sequence, parallel, for each, evaluator, best of all, and one of control flow without taking on a framework. The tradeoff is honest: it ships as an npm package with no hosted run history, dashboards, scheduling, or support contract, so operations are yours to build. Choose it for control and full type inference across nested pipelines; look elsewhere if you want a managed platform or a visual builder.

Skip Flows AI if you need a visual workflow builder, hosted run history, dashboards, or scheduling handled for you rather than assembling each of those yourself around an npm dependency in a TypeScript codebase.
Flows AI is an open-source npm package, so there is no licence fee to weigh against platform competitors — the cost shows up as engineering time. Teams with TypeScript engineers already on the Vercel AI SDK spend it as a small dependency; teams without that in-house capacity should compare the total against a hosted orchestration platform whose fee covers run history and dashboards.

What is Flows Ai?
Flows Ai — A type-safe, open-source TypeScript library for orchestrating multi-step AI workflows on top of the Vercel AI SDK. Best for TypeScript developers already building on the Vercel AI SDK, Teams wiring translation, summarization, or evaluation chains in code, Developers who want sequencing and branching without adopting a framework. Free to use.
Flows AI is a small npm package — `npm install flows-ai` — that adds structure to AI pipelines you already write in TypeScript. It was inspired by Anthropic's agent patterns and built on top of the Vercel AI SDK, so it is a library you import rather than a platform you sign up for. The core unit is a Flow, a composable structure that can be nested to arbitrary depth. Each flow carries an agent (what to execute), an input (what to process), and an optional name. Input can be a plain instruction string when the agent is a simple LLM call, or another flow, or an array of flows when you use the library's control flow agents. Agents are just async functions, so you can call an LLM or run arbitrary code inside one; an agent helper takes the same props as the Vercel AI SDK's generateText, which is how the docs wire up a translation agent with the openai provider. Execution runs through an execute function that takes your flow plus a context object holding the agents. Built-in control flow covers sequence, parallel, for each, evaluator, best of all, and one of, with custom agents as the escape hatch. It suits TypeScript developers who already build on the Vercel AI SDK and want sequencing, branching, and evaluation without adopting a larger framework.
Key features
- Type-safe flow composition with TypeScript
- Flow structure of agent, input, and optional name, nestable to arbitrary depth
- Sequence agent chains steps so each output feeds the next input
- Parallel agent runs AI tasks concurrently
- For each agent for iterative processing over inputs
- Evaluator agent grades LLM output
- Best of all agent selects the strongest result
- One of agent for branching workflows
- Agent helper accepting the same props as Vercel AI SDK generateText
- Custom agents defined as plain async functions
- Agents receive input and a shared context object
- Execution via an execute function that takes a flow plus an agents context
- Open source, installed with npm install flows-ai
- Bring-your-own model through the Vercel AI SDK (openai provider shown in docs)
Behind the verdict
Flows AI occupies a narrow, deliberate slot: it is the thin orchestration layer over the Vercel AI SDK, not a platform around it. The design is easy to hold in your head. A flow is { agent, input, name }, input can be a string, a nested flow, or an array of flows, and an agent is simply an async function called with ({ input, context }). That means the learning curve is closer to a utility than a framework — the docs' first example is two agents in a sequence, and the custom agents guide shows a repeatAgent that calls Promise.all over nested flow results in about three lines. The built-in control flow agents cover the patterns most teams actually need: sequence chains steps so each output feeds the next input, parallel runs tasks concurrently, for each iterates over inputs, evaluator grades LLM output, best of all picks the strongest result, and one of handles branching. Because the agent helper takes the same props as the Vercel AI SDK's generateText, wiring a model is a few lines and model choice stays with you — the documentation shows the openai provider with gpt-4o, and nothing binds you to a single vendor. The absence of a model of its own is the point, not a gap. Where it fits: teams that want sequencing, parallelism, and evaluation expressed in code with full type inference instead of a YAML file or a drag-and-drop canvas, and developers who would rather own their runtime than hand it to a vendor. Where it does not: non-developers, anyone expecting a visual workflow builder, and teams that need hosted run history, dashboards, scheduling, or observability such as caching, logging, and tracing out of the box — the provided documentation does not mention those. It is also not a place to look for a large catalog of pre-built third-party integrations. Treat it as a library dependency you reason about like any other, and budget engineering time for the operational layer it deliberately leaves to you.
Models under the hood
as of 2026-10-23
Limitations
- Flows AI is a library rather than a hosted service, so it brings no model of its own — you supply one through the Vercel AI SDK, and the documentation shows the openai provider with gpt-4o.
- Agents are async functions you write, which means errors, retries, concurrency limits, and cost control are your responsibility.
- The provided documentation does not mention observability features such as caching, logging, or tracing, nor does it describe enterprise support or SLAs.
- There is no visual builder and no catalog of pre-built third-party integrations; control flow is limited to the built-in sequence, parallel, for each, evaluator, best of all, and one of agents plus whatever custom agents you add.
- Adopting it presumes a TypeScript codebase and a working Vercel AI SDK setup.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Flows Ai actually fits — and what changes day-one when you adopt it.
They install flows-ai, wrap their existing generateText calls in an agent helper, and define a sequence of translation then summary agents, then run it through execute with an agents context.
Outcome: Two previously hand-wired async steps become a named, type-inferred flow they can nest and reuse elsewhere in the codebase.
They use the best of all agent to generate several candidate responses and the evaluator agent to grade them, passing the winning result downstream in the same pipeline.
Outcome: Quality selection becomes a step in the flow instead of an ad-hoc manual comparison, and the grading logic sits in version control with the rest of the code.
They write a custom agent as a plain async function — the docs' repeatAgent calls Promise.all over a nested flow's results three times — and register it in the execute context alongside the built-ins.
Outcome: A pattern the built-in agents do not cover is added without forking the library or leaving its execution model.
Use cases
- Build a translation pipeline that first translates text, then summarizes it
- Create a multi-step content generation workflow with sequential agents
- Run multiple AI tasks at once with the parallel agent
- Design an evaluation loop where one agent grades another's output
- Pick the strongest of several candidate outputs with best of all
- Branch to different agents depending on the input with one of
- Write a custom agent that repeats a nested flow N times and returns all results
- Iterate an agent over a list of inputs with for each
Setup time & first value
How long it actually takes to get something useful out of Flows Ai — broken out by persona, not the marketing-page minute.
For a TypeScript developer already on the Vercel AI SDK: npm install flows-ai, wrap an existing generateText call in the agent helper, and run one execute call — the docs' first sequence example is a plausible first sitting. Teams new to the AI SDK should add time to get a provider and API key working before flows help.
Switching to or from Flows Ai
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From hand-rolled async functions: wrap each step as an agent and replace the manual chaining with a sequence or parallel flow run through execute.
- →From a heavier orchestration framework: lift your individual agent prompts into the agent helper, which takes the same props as the Vercel AI SDK's generateText.
- →From direct Vercel AI SDK generateText calls: add flows-ai alongside the SDK you already use and convert call sites one flow at a time.
- ↗To the raw Vercel AI SDK: your agents are already functions calling generateText, so keep the agent bodies and replace the flow and execute calls with your own control code.
- ↗To a hosted orchestration platform: keep your agent prompts and port the sequence, parallel, and evaluator structure into the platform's workflow definitions.
