Vellum has a free tier; the other does not. Paid plans start at On request for LatchBio and Free for Vellum.

Does LatchBio or Vellum run on more platforms?

LatchBio runs on Web. Vellum runs on Web, macOS, iOS, Slack, Telegram, Terminal.

Can I use Vellum for free?

Yes. Vellum has a free tier, so you can try it without paying. LatchBio starts at On request.

What is LatchBio best used for?

LatchBio is most often used for a small biotech with sequencing data and no bioinformatician who needs a first pass differential expression or cell type annotation quickly, an assay or kit vendor that wants to give customers an analysis portal under its own branding rather than shipping raw files, a wet lab scientist who wants to explore a dataset interactively before commissioning a formal analysis from a core facility, a research group benchmarking agent produced analyses against its own established pipeline to decide how much routine work can be delegated. Of those, a small biotech with sequencing data and no bioinformatician who needs a first pass differential expression or cell type annotation quickly and an assay or kit vendor that wants to give customers an analysis portal under its own branding rather than shipping raw files are not what Vellum is typically brought in for.

What can LatchBio do that Vellum cannot?

LatchBio covers Agent driven analysis, Multi assay support, Published benchmarks, White labelled portals. Vellum covers Persistent AI identity, Long-term memory, Email automation, Calendar management.

The short version

Only Vellum has a free tier, so it costs nothing to try first.
Each has a real cost: LatchBio the company has pivoted from hosted bioinformatics workflows to AI agents, so organisations that adopted the earlier SDK and workflow product are now on a line that is no longer the strategic focus.; Vellum pricing varies significantly by computational tier, making budget planning difficult
They diverge on capability: LatchBio covers Agent driven analysis, Vellum covers Persistent AI identity.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

LatchBio

The company has pivoted from hosted bioinformatics workflows to AI agents, so organisations that adopted the earlier SDK and workflow product are now on a line that is no longer the strategic focus.
Agent generated analysis code has to be validated by someone who could have written it, which inverts the value proposition for the small labs that most need it and cannot check the output.
No pricing is published, so the cost of routine agent analysis at team scale cannot be estimated without contacting sales, and compute billed through the platform makes the bill usage dependent.
Regulated use is a poor fit: an agent that writes non deterministic analysis code is difficult to validate under GxP, so this is a research tool rather than something that will sit in a regulated diagnostic or submission workflow.
The vendor publishes its own benchmarks, which is more than most competitors do, but self reported benchmarks on selected datasets are not a substitute for testing the agent on your own data before committing.

Vellum

Pricing varies significantly by computational tier, making budget planning difficult
Requires explicit permission for sensitive actions, limiting autonomy
Self-hosting option may intimidate non-technical users
Learning curve to develop customizations with plugins

Answered from the vendors’ own pages

LatchBio: Is LatchBio still selling the original workflow platform?

The company is now led by agent.bio and its agent products. Buyers evaluating the older Python SDK workflow platform should confirm current support directly.

Vellum: How does Vellum protect my data privacy?

Vellum uses permission-based controls requiring explicit approval for sensitive actions. Data is encrypted and the option for self-hosting provides complete data control. Open-source deployment option allows hosting on your own infrastructure.

LatchBio: Can I try it before buying?

Yes. There is an interactive sandbox where you can upload data and run the agent before entering a sales conversation.

Vellum: Can I use Vellum for business team collaboration?

Vellum is primarily designed as a personal assistant with persistent identity. For team collaboration, platforms like Lindy offer better multi-user features with shared credit pools and Slack workspace integration.

Source

LatchBio: Is it suitable for regulated work?

Not really. Non deterministic agent generated code is hard to validate under GxP, so treat it as a research and exploration tool.

Vellum: What does the free tier include?

Vellum offers free starter credits to begin using the platform. Beyond that, it operates on a pay-as-you-go credit model with paid tiers starting at $30/month for increased computational resources and bundled credits.

Source

LatchBio: What data types does it handle?

Single cell RNA sequencing, spatial transcriptomics, epigenomics, proteomics and pharmacology data, ingesting FastQ, H5AD and spreadsheet formats.
