Lyzr vs Vellum

Two fact sheets from our own research, side by side — pricing, platforms, API access and status re-checked by us rather than quoted from the vendors. Lyzr starts at $0.08, Vellum at $30. Only Vellum has a free tier. Both ship a public API.

What our research says

Lyzr

The pitch that distinguishes it from another agent framework is the control plane over agents you did not build in Lyzr — one place for tracing, guardrails and audit across frameworks and clouds. Per-run pricing with no seat licence is unusually clean for enterprise software. Whether the governance layer earns its keep depends on how many agents you already have in production.

Pros

  • Control plane spans agents built on AWS, Azure, GCP, LangChain and custom frameworks
  • Simulation engine tests agent behaviour before it reaches production
  • Hallucination detection, PII masking and audit logging built into the run price
  • VPC and on-premises deployment keeps data out of the vendor's hands
  • Per-run pricing with no seat licences or minimum commitments advertised

Cons

  • No free tier and no self-serve trial published
  • LLM token costs sit on top of the per-run price, so the real bill is not $0.08
  • Self-hosting at $0.03 per run still means running and paying for your own compute
  • A per-run unit is hard to forecast until you know how chatty your agents are

Vellum

An ambitious personal agent that pairs deep memory with real tool access, and the MIT-licensed runtime is a rare escape hatch in this category. The company is visibly mid-pivot - its docs subdomain still describes the earlier enterprise LLM platform - so expect product churn and check that plan credits cover your actual usage.

Pros

  • Persistent memory plus real actions, not just chat
  • Open-source MIT runtime allows self-hosting without platform fees
  • Wide surface: web, macOS, iOS, CLI, Slack, Telegram
  • Transparent hosted pricing with defined compute and credit bundles

Cons

  • Brand confusion: documentation and older coverage describe a different enterprise product
  • Usage credits on top of the subscription make heavy use costlier than the sticker price
  • Company details for the current product are thin on the site

Which one fits

Choose Lyzr if you need

  • Enterprises with agents already running across several frameworks and clouds
  • Regulated teams that need audit logs, PII masking and access control over agent activity
  • Deployments that must keep data inside a company VPC or on-premises

Choose Vellum if you need

  • Individuals who want one assistant with memory across email, calendar and chat
  • Tinkerers willing to self-host an open-source assistant runtime
  • Mac-centric users who want a native app plus mobile and Slack access
