6 best BentoML alternatives for self-hosted AI model deployment (2025)

BentoML is a widely used open-source tool for packaging and serving machine learning models. It works well for local development and setting up inference endpoints.

If you’re looking for alternatives to BentoML, say to add autoscaling, get more visibility into your workloads, or support things like APIs, databases, or background jobs, this guide covers several platforms that can help.

We’ll look at platforms like Northflank, Modal, RunPod, and KServe, tools that support a mix of AI and infrastructure needs. For example, Northflank supports both AI and non-AI workloads on one platform. You can deploy model trainers, inference jobs, Postgres, Redis, and schedulers side-by-side, with autoscaling, CI/CD, logs, metrics, and secure runtimes built in.

Let’s look at a breakdown of BentoML alternatives that fit different use cases, from GPU-backed model serving to full-stack deployment.

Quick comparison: BentoML alternatives for AI and infrastructure workloads

If you're looking into other options beyond BentoML, this section covers platforms that support model serving, training, and broader application needs:

  1. Northflank – For teams that want to run AI models and full applications side by side on the same platform. Supports model serving, training jobs, APIs, background workers, and databases like Postgres and Redis. Built-in autoscaling, monitoring, and continuous delivery. You can also run GPU workloads in your own cloud using Bring Your Own Cloud (BYOC).
  2. Modal – Designed for running Python functions and ML inference at scale. Autoscaling is handled for you, with minimal infrastructure setup required.
  3. RunPod – Lets you run custom containers on GPU machines. Helpful for training and inference workloads, especially when you want access to spot instances or specific GPU types.
  4. Anyscale – Built around Ray for distributed compute. Useful for teams that are already using Ray to manage large-scale training jobs or data pipelines.
  5. Baseten – Offers a low-code UI for deploying models, with autoscaling and basic observability tools included. Good for ML engineers who want to focus on iteration.
  6. KServe – An open-source model serving framework built for Kubernetes. Best suited for infrastructure-savvy teams that prefer OSS and want to run models in-cluster.

Deploy models, jobs, and full applications on a single platform

What to look for in a BentoML alternative

BentoML is useful for serving models, but if you're working toward production or managing multiple services, it helps to step back and ask what else your team might need.

  1. Do you need to serve models only, or are you also training them regularly?

    Some platforms focus on inference, while others let you run full training pipelines, manage datasets, and schedule recurring jobs all in one place.

  2. Are you building a single endpoint, or do you want to run supporting services like APIs, schedulers, Redis, or Postgres alongside your model?

    If your application depends on other services, it helps to deploy everything together with shared monitoring, networking, and deployment flows.

  3. Do you need autoscaling and monitoring that work outside the BentoML runtime?

    In production, you’ll likely want infrastructure-aware metrics, logs, and autoscaling that adapt to actual usage, not limited to what BentoML provides by default.

  4. Is multi-cloud or BYOC (Bring your own cloud) GPU flexibility important to your team?

    Some teams want full control over cloud costs and GPU usage. Bring Your Own Cloud (BYOC) setups let you run on your own infrastructure without giving up developer experience.

  5. Do you want to build an internal AI platform, not only an endpoint?

    For teams building long-term ML infrastructure, it's useful to have secure runtimes, RBAC, CI/CD, and the ability to scale across multiple apps and teams.

Next, we’ll look at 6 BentoML alternatives that support some or all of these needs in their own way.

Why Northflank is a production-grade alternative to BentoML

BentoML is focused on model serving, but when your team needs to go beyond inference, like running APIs, databases, or background jobs alongside your models, that’s where Northflank stands out.

Northflank gives you a single platform where you can deploy both your AI workloads and any other workloads, so you’re not restricted to serving models alone. You also get built-in autoscaling, monitoring, and production-grade infrastructure controls.

What makes Northflank a complete alternative:

  • Deploy models, APIs, Redis, Postgres, and workers in one place
  • Run GPU-powered jobs for inference, fine-tuning, and batch processing
  • Autoscaling is built-in, no need for manual configuration
  • Built-in monitoring, logs, cost tracking, RBAC, and GitOps pipelines
  • Supports both AI/ML and traditional web workloads together
  • SOC 2-aligned: deploy to private clusters, with secure runtimes and audit logs

Northflank isn’t limited to inference. You can run your entire AI stack and full application infrastructure together with autoscaling, monitoring, and BYOC GPU support built in.

Frequently asked questions about BentoML alternatives

These common questions come up when teams are checking out BentoML and looking at broader deployment options.

1. What is BentoML used for?

BentoML is a framework for packaging and serving machine learning models. It helps developers deploy models as REST or gRPC services with Python-friendly tooling.

2. Is BentoML good?

Yes, it’s well-suited for teams that want a lightweight, Python-native way to serve models locally or in simple cloud setups. For larger-scale deployments or teams that need autoscaling, monitoring, and full application infrastructure, platforms like Northflank are often used.

3. Is BentoML open-source?

Yes, BentoML is open-source under the Apache 2.0 license. You can self-host it or use it as part of a larger MLOps toolchain.

4. What are the advantages of BentoML?

It’s Python-first, easy to get started with, and integrates well with many ML frameworks. That said, it focuses mainly on model serving. Teams needing to manage full application workloads or deploy in production environments often look to tools like Northflank for additional infrastructure control.

5. What are machine learning ops?

Machine learning operations (MLOps) is the practice of managing the lifecycle of ML models, from training and deployment to monitoring and retraining. BentoML covers serving, but broader MLOps may involve tools for orchestration, pipelines, observability, and compliance.

Choosing a BentoML alternative that fits your deployment goals

BentoML is great if you want a Python-based model server that keeps things simple. However, once you need autoscaling, full observability, or the ability to deploy APIs, jobs, and databases alongside your models, you’ll need more than a model server.

That’s where platforms like Northflank come in. You can run both AI workloads and full applications on a unified platform, with built-in CI/CD, logs, metrics, and autoscaling, plus support for GPUs and BYOC when needed.
