The short version

  • Only Fused has a free tier, so it costs nothing to try first.
  • Each has a real cost: CARTO no prices are published; the committed tiers are all quote-only; Fused the price steps are brutal: $20 to $200 to $2,000 a month with no intermediate tier, so a two-person team that outgrows Starter faces a tenfold increase for what is often a modest capacity gap.
  • They diverge on capability: CARTO covers Spatial Analysis, Fused covers User defined functions.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

  • An analyst prototyping against Overture, Sentinel or Census data who needs a working map in an afternoon rather than a data engineering ticketnot CARTO
  • An application that needs a geospatial computation exposed as an HTTP endpoint, where the alternative is a container, a queue and an on-call rotanot CARTO
  • A consultancy delivering an interactive constraint or suitability map to a client, computed live from source data rather than pre-baked into static tilesnot CARTO

Where each one falls short

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

CARTO

  • No prices are published; the committed tiers are all quote-only
  • Metered on four separate axes: workflow runs, map loads, API calls and location data service operations
  • API access and tokens are limited on pay-as-you-go and unlimited only from the Strategic tier
  • Self-hosting is available on Enterprise and included only on the Custom tier
  • The 14 day trial explicitly forbids production use

Fused

  • The price steps are brutal: $20 to $200 to $2,000 a month with no intermediate tier, so a two-person team that outgrows Starter faces a tenfold increase for what is often a modest capacity gap.
  • Published tiers do not state the actual compute, storage or request allowances, so the only way to know whether $200 covers your workload is to run it and find out.
  • Fused is at pre-seed stage with a small team, and putting a customer-facing map behind a startup’s serverless platform is a continuity risk that a procurement review will flag.
  • It is Python-only and assumes competence with cloud-native geospatial formats; there is no path for an analyst who works in a desktop GIS and not in code.
  • Serverless execution means cold starts and per-tile latency on uncached views, so a first load of a heavy UDF over a wide area is noticeably slower than a pre-rendered tile set.

Can I use Fused for free?
Yes. Fused has a free tier, so you can try it without paying. CARTO starts at On request.
What is CARTO best used for?
CARTO is most often used for spatial analysis over data already in a cloud warehouse, building interactive maps and location dashboards, geocoding and routing through location data services, site selection and territory planning. Of those, spatial analysis over data already in a cloud warehouse and building interactive maps and location dashboards are not what Fused is typically brought in for.
What can CARTO do that Fused cannot?

Answered from the vendors’ own pages

CARTO: What CARTO pricing tiers are available?

CARTO offers Pay As You Go (monthly, consumption-based), Enterprise (annual commitment with limited quotas), Strategic (annual with unlimited API access), and Custom (annual with full services for large enterprises). Enterprise and higher require contacting sales.

Source
Fused: What does Fused actually give me?

A Python function becomes a map tile endpoint and an HTTP API on managed infrastructure, with caching, without you running a server.

CARTO: Does CARTO have a free version?

CARTO does not advertise a free tier. The Pay As You Go plan requires monthly payments based on consumption with capped services.

Source
Fused: How much does it cost?

Free, then $20, $200 and $2,000 per month for Starter, Developer and Professional. Usage allowances are not itemised publicly.

CARTO: What is included in the CARTO Strategic plan?

Strategic tier includes unlimited API access and tokens, premium or elite support, custom branding, audit logs, and usage metrics. It requires an annual commitment and custom pricing quote.

Source
Fused: Can I run UDFs locally?

Yes, through the Python SDK, which is how most development is done before deploying.

Fused: Does it replace PostGIS or BigQuery?

No. It reads from them. Fused is the compute and serving layer, not the store.

Fused: Is it a mature company?

No. It is a small pre-seed San Francisco company. The technology is real; the vendor risk is real too.
