What is Manifest?
Manifest lets developers bring multiple model providers behind one API. It supports model configuration, provider switching during outages, repair of some incorrect requests, usage tracking, and limits on agent budgets.
According to its documentation, Manifest lets you:
- bring multiple model providers behind one API
- configure models and their parameters
- switch to another provider during an outage
- repair some incorrect requests
- track calls, tokens, and spending
- limit agent budgets
We file it under Model APIs and platforms, the category of tools to access models through an API, and it also overlaps with lLMOps and observability and developer tools. The category lists 23 verified tools on this site.
The publisher is MNFST, Inc., based in United States.
Who is it for?
It is mostly useful to these profiles: developers. The need it covers is simple to state: access models through an API.
Manifest is a good candidate if:
- you want to try before paying
- you plan to connect it to your tools or automations through its API
- you want to read the code or host it yourself
Before deciding, run a trial on a real task and measure the time saved: it is the only criterion that really counts.
How much does Manifest cost?
Pricing model: open source (public code). A free plan is offered, usually limited in volume or features.
The first paid plan costs $19 per month (Hosted Pro. The free Cloud plan is announced until November 1, 2026; self-hosting remains free), according to the pricing page, checked on October 24, 2026.
Per month, that is more expensive than the category median ($14 per month, based on tools with a published price).
To estimate what the same work would cost done directly with an AI model, use our API price calculator. Prices change often: always check the official site before subscribing.
Data and privacy
The publisher does not clearly state where data is hosted. Assume your content may leave your region.
For professional use, check that a data processing agreement (DPA) is offered, and do not send customers' personal data or confidential documents without one.
No export feature is documented: keep a copy of your content elsewhere.
Three habits apply to every AI tool:
- turn off the use of your content for training if the option exists
- use a work account separate from your personal account
- review everything the tool produces before publishing or sending it
Platforms, languages and API
Manifest runs on: web browser and API.
Interface languages: English.
A public API lets you call it from your own programs or an automation tool, and plug it into an AI agent.
The source code is public: mnfstmnfst/llm-gateway.
How we scored it
