It's a split decision.
CARTO is a cloud-native GIS for teams running spatial analysis and visualization in a data lakehouse such as BigQuery. MapTiler Cloud is a mapping platform with web and mobile SDKs, location APIs, published usage quotas and an on-premises option. Choose CARTO when analysis workflows and organizational data are the main job. Choose MapTiler when you need to build map features into an application and want a free tier, clear Flex pricing or self-hosted deployment.

02Pricing at real usage
MapTiler Cloud has a free tier with 5 GB storage, one file, 5k sessions and 1k search sessions per month, plus 100k API requests and 100 uploads. Flex costs $30/month and includes 10 GB storage, 25k sessions, 3k search sessions, 500k API requests and three team members. The pricing page lists extra Flex sessions and search sessions at $2.50 per 1k, API requests at $0.15 per 1k, and storage from $20/month for 100 GB. Listed prices exclude VAT.
CARTO lists a 30-day trial and metered Pay As You Go, plus committed tiers billed annually upfront. Its pricing page does not publish amounts, so compare expected usage and quotas with the vendor before budgeting. The listed tiers describe differing annual quotas and API or token access.
03API, SDKs and integration
CARTO centers integration on cloud data ecosystems: its homepage names BigQuery and says spatial work can run in a data lakehouse. For app development, it describes framework-agnostic apps and visualization with deck.gl, WebGL and GPU technology. It also refers to building with existing agents and APIs. The homepage does not name a language-specific CARTO SDK.
MapTiler Cloud is aimed at embedding mapping features in applications. Its homepage names a TypeScript SDK, JavaScript SDK and mobile SDKs, alongside an API reference. The listed capabilities include interactive maps, data visualization, weather displays, static maps and 3D maps. Its location services cover search and geocoding, IP location, elevation lookup and coordinate transformation. The homepage links to documentation and an API reference; it does not name a CLI. For data workflows, MapTiler lists TIFF, GeoJSON, KML and GPX among supported upload formats. CARTO names BigQuery; MapTiler's homepage does not name third-party integrations.
04Open source, self-hosting and lock-in
Neither vendor states an open-source licence for its platform on the homepage. MapTiler offers an on-premises route to host and serve maps or process geodata, including in offline environments. CARTO describes a cloud-native platform that connects spatial work to cloud data ecosystems, including BigQuery; its homepage emphasizes keeping data in BigQuery rather than moving it through ETL.
That gives MapTiler a clearer deployment option when infrastructure control or offline use is a requirement. It does not, by itself, establish how portable every map style, API integration or workflow will be. MapTiler lists geodata formats including TIFF, GeoJSON, KML and GPX, which can inform a migration plan. Before committing to either platform, ask how to export source data, map configurations and analysis outputs, and what work is required to recreate them elsewhere.
Questions people ask
Is CARTO or MapTiler Cloud better for building a web map?
MapTiler Cloud is the more direct fit for adding maps to web and mobile applications: it lists TypeScript, JavaScript and mobile SDKs, plus APIs for location services. CARTO supports app development too, but its product emphasis is spatial analysis and visualization in a data lakehouse.
Does CARTO have a free plan?
CARTO lists a 30-day free trial, but no free plan. Its pricing options include metered Pay As You Go and committed tiers billed annually upfront. The vendor does not publish the prices for those tiers, so ask for a quote based on expected usage and API access.
How much does MapTiler Cloud cost?
MapTiler lists a free tier and a Flex plan at $30 per month. Flex includes 25k sessions, 3k search sessions and 500k API requests monthly, among other quotas. Additional usage is priced by unit, and the listed prices exclude VAT. Custom pricing is available for higher-volume needs.
Can MapTiler Cloud be self-hosted?
MapTiler offers on-premises options to host and serve maps or process geodata, including for offline environments. Its homepage presents this as a separate deployment path. Check with the vendor which services, data and operational requirements apply to the specific self-hosted setup you plan to use.
