The short version

  • Only Fused has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; TomTom Developer Portal default rate limits on self-serve plans are modest at approximately 5 requests per second; higher limits require contracts
  • They diverge on capability: Fused covers User defined functions, TomTom Developer Portal covers Core Functionality.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

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

TomTom Developer Portal

  • Default rate limits on self-serve plans are modest at approximately 5 requests per second; higher limits require contracts
  • Limited POI rich media compared to Google Places; no reviews, photos, or user-generated content
  • Smaller developer community with fewer tutorials and Stack Overflow answers than Google or Mapbox
  • No official Flutter SDK; developers must use third-party plugins for Flutter integration
  • Maps SDK for Web v6 deprecated as of February 2026 with migration required to newer SDK

Answered from the vendors’ own pages

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.

TomTom Developer Portal: Does TomTom Developer Portal have a free tier?

Yes. TomTom offers a freemium plan with 50,000 tile requests plus 2,500 non-tile requests daily at no cost with no credit card required, and commercial use is permitted.

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.

TomTom Developer Portal: What APIs does TomTom provide?

TomTom provides REST APIs for Maps (display raster or vector maps), Navigation (routing and turn-by-turn), Places (geocoding and POI search), and Traffic (real-time flow and incidents), plus JavaScript SDK and mobile SDKs.

Source
Fused: Can I run UDFs locally?

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

TomTom Developer Portal: What JavaScript SDKs are available?

TomTom provides Maps SDK for JavaScript with TypeScript support, a Services library as a wrapper for REST APIs, and mobile integration through NativeScript WebView for iOS and Android.

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.
