The short version
- Each has a real cost: Amazon Q Developer deepest value and AWS-specific expertise is tied to the AWS ecosystem, less compelling for non-AWS shops; Seldon seldon Core v2 is under the Business Source Licence rather than Apache 2.0, so production use requires a commercial agreement, and a team that evaluated it believing it was open source discovers the licence is the blocker exactly when the project is ready to ship.
- They diverge on capability: Amazon Q Developer covers Code generation, Seldon covers Kubernetes custom resources.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Amazon Q Developer
- Deepest value and AWS-specific expertise is tied to the AWS ecosystem, less compelling for non-AWS shops
- Free tier caps agentic requests at 50 per month, which can be exhausted quickly on larger tasks
- Additional transformation usage beyond plan limits is billed per line of code, adding unpredictable costs
- GitHub and Eclipse integrations are still in preview, indicating incomplete platform coverage
Seldon
- Seldon Core v2 is under the Business Source Licence rather than Apache 2.0, so production use requires a commercial agreement, and a team that evaluated it believing it was open source discovers the licence is the blocker exactly when the project is ready to ship.
- Core v1 remains Apache 2.0 but is in maintenance, so taking the free route means running software that receives no new development while the architecture it belongs to moves on without it.
- Version 2 is a different system rather than a newer release, with different custom resources, a scheduler component and a Kafka-based pipeline model, so migrating from v1 is a re-implementation of every deployment manifest rather than an upgrade.
- Kafka is a dependency for v2 pipelines, so an organisation that does not already operate it takes on a distributed log with its own storage, retention, rebalancing and failure modes purely in order to serve models.
- Everything assumes Kubernetes fluency and the failure modes are Kubernetes failure modes, custom resource version mismatches, an operator that will not reconcile, admission webhooks and resource limits terminating an inference pod mid-request, so it needs a platform engineer rather than a data scientist.

Answered from the vendors’ own pages
Amazon Q Developer: What does Amazon Q Developer cost?
There is a free tier with no cost, and a Pro tier priced at $19 per user per month that adds expanded agentic request limits, admin controls, and IP indemnity.
SourceSeldon: Is Seldon open source?
Partly, and this is the thing to check before you build on it. Core v1 is Apache 2.0 but in maintenance. Core v2 was moved to the Business Source Licence in 2024, which allows evaluation but not unlicensed production use. Verify the current licence of each component you intend to run, including MLServer and the Alibi libraries.
Amazon Q Developer: What are the limits on the free plan?
The free tier includes 50 agentic requests per month, access to the latest Claude models in IDE and CLI, and 1,000 lines of code per month for Java transformation.
SourceSeldon: What is the difference between v1 and v2?
Architecture, not just version number. v2 introduces a scheduler, a different set of custom resources and Kafka-backed pipelines. Manifests, mental model and operations all change, so treat a move as a project.
Amazon Q Developer: How is usage metered beyond plan limits?
Java and .NET transformation usage beyond the plan's included lines of code is billed as overage at $0.003 per line of code submitted.
SourceSeldon: Do I need Kubernetes?
Yes. It is a Kubernetes-native system and there is no meaningful deployment without a cluster and someone competent to run it.
Amazon Q Developer: Can I cancel my Amazon Q Developer Pro subscription anytime?
Subscriptions are billed monthly per user and prorated in the first month, but canceling before the end of a billing month still incurs the full month's subscription fee.
SourceSeldon: What is MLServer?
Seldon's Python inference server implementing the Open Inference Protocol, usable inside Seldon deployments or on its own. Check its current licence alongside Core's, since the company has moved projects onto the Business Source Licence.
Amazon Q Developer: What counts as an agentic request?
Agentic requests include both question-and-answer chat interactions and autonomous coding tasks performed by Q Developer's agents, all drawn from the same monthly quota.
SourceSeldon: Do I have to run Kafka?
For v2 pipelines, yes. If you only need single models served, that dependency is a large amount of infrastructure for the benefit, and a simpler serving layer may be the better answer.
