How Runflow compares
The platforms below hand you an API key. Runflow is a managed service: our team scopes the solution, builds the pipeline, runs it in production, and Sentinel scores every output before it reaches your users.

Feature matrix
The first four rows are the ones that decide the project: who builds the pipeline, who runs it, who helps you integrate it, and who checks the output. The rest are the feature-by-feature facts.

Managed service
A working integration, built and run for you
Every platform on this page sells self-serve access. Your team then owns the model choice, the pipeline, the retries, the quality bar, and the scaling. Runflow works the other way around: we take the use case and hand back something your product can call on day one.
01
We scope the solution
25 minutes on your use case, your volume, and your quality bar. We tell you what we would run and what it costs.
02
We build and host it
Our team builds the pipeline and hosts every model it needs. Sentinel gets wired into it before you ship.
03
We help you ship it
You get the API key, plus our help on the integration and on how the interface should behave in your product.
A one-off build starts at $7,500 per workflow, or commit from $500 a month in API spend on a 12-month term and the builds, maintenance, and lower per-call rates come included.
Only on Runflow
Sentinel scores every output in production
At scale, image models produce bad frames: distorted faces, wrong garment fit, artifacts in the background. None of the platforms in this comparison score output quality before delivery. Sentinel evaluates each generation across 8 dimensions, blocks anything below your threshold, and retries it automatically. BetterPic generates 240 candidates per user, Sentinel scores all of them, and only the top 60 get delivered. Manual QA gone.
What makes Runflow different
We build the pipeline
Our team scopes the solution, picks the models, and builds the pipeline on infrastructure we already run. Every model it needs is hosted here.
We run it in production
Retries, failover, scaling, and model upgrades stay with us. You get one API key, one invoice, and a pipeline that keeps working. No AI hires required.
We help you integrate it
We work through how the flow fits your product, down to how the interface should look and what the user sees while a job runs. Your team ships to customers instead of researching models.
Sentinel scores every output
Sentinel evaluates each generation across 8 dimensions before delivery and retries anything that fails your threshold. Every other platform on this page delivers whatever the model produced.
Multi-provider reliability
Automatic failover across inference providers. When one goes down, traffic moves to the next. Enterprise SLAs without single-provider risk.
ComfyUI native
Any ComfyUI workflow deploys as a single API endpoint, loops and conditional logic included. Full custom node support. Dev/staging/prod environments with version history and rollback.
Not sure which platform fits?
Bring your use case, your volume, and your current bill. In 25 minutes we map what we already run onto your product, tell you what we would build, and what it costs to have us run it.
