Lyzr vs Stack AI (2026): which should you pick?

Pick Lyzr if

• Fits if you want to build and test agents free before talking to sales
• Makes sense if your company needs one place to track and govern its agents

Look elsewhere if

• Pricey if you want help, as the proof of concept is $20,000 for 4 weeks
• Not for you if you want published team pricing, since governance and workflow plans are custom
• Watch out: credits are added as a team grows, and prices are billed yearly in US dollars
• Watch out: fine-tuning and on-prem hardware are extras priced with you

Pick Stack AI if

• Fits if you want to build one or two agents and try them free
• Makes sense if you plan to ask for an enterprise deployment later

Look elsewhere if

• Tight if you work in a team, as Free is 1 seat and 2 projects
• Not for you if you want a self-serve paid plan, because none is published
• Watch out: SSO, access control, VPC and on-prem are Enterprise only
• Watch out: the homepage says Asana acquires StackAI, so ownership and plans may change

Lyzr

Agent Studio and Architect

Build agents visually or turn a plain-language brief into a working agent, test against a sandbox, and move them to production without rebuilding.

Opencontroller governance

A control plane that lists every agent, gives each an owner and release gate, and applies policies and spend limits, including to agents built on other platforms.

Workflow automation service

For complex processes, Lyzr's engineers build multi-agent workflows with your team, hosted by Lyzr, in your cloud or on-prem.

Model choice

You use the model provider you already pay for or open-weight models on your own hardware; Lyzr states it does not bill for tokens.

Fine-tuning and on-prem hardware

Openfinetuner trains open-weight models on your data, and Lyzr Optimus is an on-prem appliance that can run air-gapped; both are priced individually.

Stack AI

Ways to ship an agent
