The short version

  • Free plans on both; paid from $250/mo and $18.99/mo.
  • Only Chroma lists embedded mode; only Pieces for Developers lists activity Timeline.
  • Where Pieces for Developers falls short: requires installing and running a background desktop app rather than being purely cloud-based.
  • Prices and features on this page were last checked on 13 November 2026.

Where each one falls short

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

Chroma

  • On a single node, available memory sets a hard upper bound on collection size, roughly 245,000 records per gigabyte of RAM at 1024 dimensions, so capacity planning is a memory purchase and the ceiling arrives without warning
  • Single-node queries parallelise only up to the number of vCPUs, after which requests queue and latency rises linearly with concurrency, so throughput problems appear as a slow application rather than as errors
  • The distributed deployment behind Chroma Cloud is a different architecture from the embedded library, so latency, consistency and failure behaviour observed in a local prototype do not predict production behaviour
  • The open source server has no built-in authentication or multi-tenancy worth relying on, so a self-hosted deployment needs its own auth proxy and network controls before anything untrusted can reach it
  • The project has moved quickly through major internal rewrites and version changes, so upgrades have historically involved data migrations and client changes, and pinning versions is necessary rather than cautious

Pieces for Developers

  • Requires installing and running a background desktop app rather than being purely cloud-based
  • Free tier trial of Pro features requires a credit card and reverts after 7 days
  • Local-first storage means memory is not automatically synced across multiple machines without Enterprise controls
  • Effectiveness depends on the breadth of integrations enabled, which adds setup overhead

Answered from the vendors’ own pages

Chroma: Do I need to run a server?

No. Chroma runs embedded in your process with persistence to a local directory, which is how most projects start. The server and distributed modes exist for when multiple clients or larger collections require them.

Pieces for Developers: Does Pieces store my data in the cloud?

Pieces stores captured data on-device by default, giving users granular controls to pause, disable or delete captures rather than relying solely on cloud storage.

Source
Chroma: How large can a single node get?

The project puts single-node deployments at fewer than about ten million records across a handful of collections, with collection size bounded by system memory at roughly 245,000 records per gigabyte at 1024 dimensions.

Pieces for Developers: Is there a free plan for Pieces?

Pieces does not offer a permanently free plan; new users instead get a 7-day free trial on any plan, which requires a credit card to start.

Source
Chroma: Is Chroma Cloud the same software?

It is the same API and project, but the distributed deployment is a different architecture, using independent services, object storage and SSD caches rather than a single process. Behaviour under load differs accordingly.

Pieces for Developers: What does the Pro plan cost?

Pro is $18.99 per month billed monthly, with roughly a 25% discount available when billed yearly.

Source
Chroma: How does it compare with pgvector?

pgvector keeps vectors in a Postgres database you already operate, with SQL, joins and transactions. Chroma is a dedicated retrieval engine with a lower setup cost and a retrieval-shaped API. If you already run Postgres, pgvector removes a system; if you do not, Chroma removes a decision.

Pieces for Developers: What does the Enterprise plan add?

Enterprise costs $22.99 per month (or $69.99 per quarter) and adds organization-wide admin controls, approved AI providers, and governance over captured data.

Source
Chroma: What licence is it under?

Apache 2.0, which permits self-hosting and embedding in commercial products without a competing-use restriction.

Pieces for Developers: Can I cancel my Pieces subscription?

Yes, users can upgrade, downgrade, or cancel anytime from account settings, and all plans include a 14-day money-back guarantee.
