## Overview

Manifest is an open-source LLM gateway aimed at the reliability problem rather than the model problem. Instead of asking teams to standardise on one provider, it exposes a single OpenAI-compatible endpoint through which agents, coding harnesses and applications can reach OpenAI, Anthropic, Google, subscription plans, bring-your-own-key providers, custom endpoints and local servers such as Ollama, LM Studio or llama.cpp. Routing rules and model parameters are configured visually per route, so behaviour changes without touching application code.

Its signature feature is Autofix. The project cites Datadog data that roughly 5% of LLM API calls fail in production, many for avoidable reasons, and Manifest inspects each request before it reaches the provider to repair malformed payloads on the fly. Combined with automatic fallbacks when a provider degrades, full request and response body logging, and cost breakdowns per agent, key and provider, the gateway acts as a control plane for inference rather than a simple proxy.

The project is fully open source with a self-hosted Docker edition and a hosted cloud option for faster onboarding, supported by a community and an error catalog classifying common provider errors. The hosted tier's pricing lives on the site's pricing page, while the open-source gateway itself is free to run on your own infrastructure.

## Pricing & Plans

The gateway is free and open source, with a hosted cloud version for easier onboarding and paid tiers for teams and platforms; exact plan pricing is published on Manifest's pricing page.

## Key Features & Capabilities

- **Single endpoint routing:** One OpenAI-compatible endpoint reaches every configured model, provider, subscription plan or local server.
- **Autofix request repair:** Broken or non-conforming LLM requests are repaired automatically before the error reaches your agent or app.
- **Fallbacks and reliability:** Automatic retry on another provider when one goes down keeps agents and workflows running.
- **Cost and observability:** Track every request, token and dollar broken down by agent, key and provider, with full request and response body logs.
- **Self-hosting and local models:** Run the router on your own infrastructure and decide exactly what goes to the cloud and what stays local.

## Primary Use Cases

- **Unifying model access for agents (AI agent builder):** Point coding agents and agent harnesses at one endpoint to mix subscription plans, BYOK providers and local models with custom routing.
- **Controlling inference spend (Platform or engineering lead):** Get per-agent, per-key and per-provider cost and token tracking so inference spend becomes visible and attributable.
- **Reducing AI downtime (SaaS engineering team):** Use Autofix and provider fallbacks to keep customer-facing AI features working when a provider degrades or a request is malformed.
- **Keeping data local (Security-conscious developer):** Self-host the router and route sensitive workloads to Ollama or llama.cpp while sending only approved traffic to cloud providers.

## Strengths

- Open source and self-hostable, with no black box between your agents and providers
- Autofix and automatic fallbacks tackle the real failure rate of production LLM calls
- Cost and token observability by agent, key and provider makes spend accountable
- Supports subscriptions, BYOK, custom providers and local models in one router

## Limitations

- Self-hosting requires Docker and some infrastructure ownership
- Younger project than large commercial gateways, so some enterprise governance needs custom work

## Frequently Asked Questions

### Is Manifest free?
The core gateway is fully open source and free to self-host via Docker. A managed cloud version is available with onboarding support, and there is a paid tier for teams and platforms needing more.

### Where does my inference data go?
In self-hosted deployments the whole router runs on your own infrastructure, and you can route to local servers like Ollama, LM Studio or llama.cpp so nothing leaves your machines unless you choose the cloud.

### What is Autofix?
Autofix is Manifest's request-repair layer. When an LLM API call would fail because of a malformed or incompatible request, the agent fixes it before the error reaches your application.

### Can I use my existing provider subscriptions?
Yes. You can add API keys for popular providers or OAuth tokens for subscription plans, plus define custom providers and local models.
