Manifest vs one-api
Side-by-side comparison of features, pricing, ratings, and alternatives.
Manifest is an open-source LLM gateway and router for AI agents. It helps developers and teams make reliable LLM calls by automatically fixing bad API requests on the fly, routing across providers, supporting local models and BYOK, and providing full observability into every request, token, and dollar spent.
one-api is an LLM API management and key redistribution system that supports multiple providers under a single API. It provides a unified interface for managing keys and redistributing them to various applications. The system is designed to be easy to use and deploy, with a single binary and Docker-ready architecture.
All prices are listed in USD as shown.

The Verdict
AI-generated from listing dataIf you need a free, simple, single‑binary gateway for major LLM providers, one‑api is the safer default; Manifest adds paid features like autofix, local model routing, and richer observability at a cost.
Key differences
- •Pricing: one‑api is free; Manifest requires a subscription.
- •Advanced reliability: Manifest offers Autofix and automatic model fallbacks; one‑api does not.
- •Local model support: Manifest can route to Ollama, LM Studio, llama.cpp; one‑api only proxies cloud providers.
- •Observability: Manifest provides full request/response logs and cost visualisation; one‑api offers basic usage tracking.
- •Deployment maturity: one‑api ships as a single binary/Docker image with minimal setup; Manifest’s cloud version and some features are still in waitlist.
Pricing & value
one‑api is free and open source; Manifest is a paid subscription.
Ease of use / learning curve
one‑api deploys via one command binary or Docker; Manifest adds UI setup and waitlist for Autofix.
Features & depth
Manifest includes Autofix, model fallbacks, full body logs, cost visualisation, and local model routing.
Integrations & ecosystem
Manifest supports all popular providers, OAuth tokens, and local servers; one‑api covers major cloud providers but no local models.
Support
Manifest backed by Berkeley SkyDeck, Inria, active community; one‑api limited to GitHub issues and forum.
Scalability
Both are self‑hosted Docker solutions; scalability depends on user’s infrastructure.
Security & privacy
Both are self‑hosted, giving users control over keys; no differing security claims in facts.
Choose Manifest if…

Common questions
Is there any cost to use one‑api?
No, one‑api is free and open source.
Can I run local LLMs with one‑api?
Not specified; one‑api only lists cloud providers.
What happens if an upstream LLM request fails?
Manifest can automatically retry via Autofix and model fallbacks; one‑api has no such capability.
