    Get Started

    Built for Real Applications

    A full-stack UK maps API using OpenStreetMap data. Geocoding API, routing API, isochrone API, distance matrix, postcode boundary API and more. These are features the big mapping providers simply do not offer.

    • Forward & Reverse Geocoding API

      UK geocoding API: address to coordinates, coordinates to address. Full UK postcode support. Works with street addresses, landmarks, and partial postcodes. No separate billing per lookup.

    • Routing API: Turn-by-Turn Directions

      Drive, walk, or cycle. Full maneuver instructions with distance and duration per step. Multi-waypoint routes. Response matches the standard Directions API format exactly.

    • Isochrone API: Travel Time Zones

      Show the reachable area within 15, 30, 45, or 60 minutes from any point, for driving, walking, or cycling. GeoJSON output, render directly on your map. Used for catchment area analysis, site selection, delivery zone planning, and service coverage mapping. This isochrone API is included in the UK platform as standard. Not available in standard mapping APIs.

    • Distance Matrix

      Travel time and distance from multiple origins to multiple destinations simultaneously. Perfect for "which of our sites is closest?" queries. Up to 10×10 pairs per request.

    • Postcode-to-Postcode Distance

      Two UK postcodes in, road distance and drive time out, all in a single call. No geocoding step, no coordinate wrangling. Answers in miles and minutes, ready to drop straight into a spreadsheet. Built for mileage logs, journey costing, and expense claims. Drive, walk, or cycle.

    • Nearby Amenity Search

      Find the nearest hospital, pharmacy, GP, supermarket, pub, school, parking, and 13 more categories, within any radius from any point.

    • Vector Tiles

      Vector map tiles for Great Britain, Ireland, the Isle of Man, Jersey, and Guernsey. Render and style them however you like. No per-map-load fees, ever.

    • Elevation Profile

      Elevation data returned along every route. Visualise rise and fall for cycling and walking applications. Total ascent, descent, max and min elevation included.

    • Place Text Search

      Free-text search for places, businesses, and points of interest across Great Britain, Ireland, the Isle of Man, Jersey, and Guernsey. No Places API billing, ever.

    • API Key Authentication

      Per-site API keys with usage logging. See which key is making which requests. Rate limiting included. Revoke individual keys without affecting others.

    • Point Elevation Queries

      Query elevation in metres at any coordinate or along a polyline via a dedicated endpoint matching the standard Elevation API structure. Also visualised as an interactive profile chart in the map component.

    • Drop-In Navigation Widget

      A single-file PHP widget you embed via iframe. Five modes in one file: full turn-by-turn navigation, live customer tracking, fleet dispatch overview, coverage radius, and a server-side travel-time API. No npm, no SDK, no framework. Paste the iframe, point it at your API key, done.

    • Maps API WordPress Plugin

      A Gutenberg block for any WordPress site. The only maps API WordPress plugin built specifically for UK coverage. Set a postcode and miles, get a polished radius coverage map on your page. Your API key is stored server-side in WordPress options, never exposed to visitors. This maps API WordPress plugin ships free with any paid plan.

    Drop-In Map Component Included

    Every plan includes a production-ready, self-contained HTML map page. Drop it on any website. Point it at your subscription credentials. Done.

    • Live GPS Navigation

      Full turn-by-turn navigation mode. Map follows and rotates with your heading. 45° tilt perspective view while driving.

    • Voice Guidance

      Spoken voice instructions via the Web Speech API. Reads each maneuver as you approach it. Mute toggle. Zero dependencies.

    • Off-Route Detection

      Silently reroutes if you stray more than 50m from the planned route. Announces "Recalculating" and redraws instantly.

    • Speed Display

      Live speed readout in km/h from the GPS signal. Amber warning if you exceed a configurable threshold per travel mode.

    • Draw Radius

      Draw precise radius circles in miles, km, or metres from any searched location. Shows enclosed area in km². Stack multiple rings.

    • Measure Distance

      Click multiple points on the map to measure total distance. Running total in km, miles, and metres. No API call needed.

    • Drop & Export Pins

      Drop named pins anywhere on the map. Export the complete set as a CSV with label, latitude, longitude, and notes.

    • Heatmap Layer

      Paste in a list of coordinates, hit Draw. Instant density heatmap rendered on the map. Useful for visualising client or delivery locations.

    • Share Route Link

      Generate a shareable URL that reloads any route with origin, destination, and travel mode. No database required.

    • Export Map as PNG

      One-click export of the current map view as a timestamped PNG. Captures everything visible including routes, pins, and zones.

    • Right-Click Location Info

      Right-click anywhere on the map for the address, exact coordinates, and an Open Location Code (Plus Code), computed offline, no extra API call.

    • Find Nearest

      One-tap search for the nearest hospital, pharmacy, GP, dentist, nursing home, supermarket, fuel station, and more, plotted directly on the map.

    • Offline Map Caching

      A Service Worker caches map tiles as you browse and navigate. Routes load from cache when connectivity drops, so no missing tiles mid-journey. Essential for field work and navigation in areas with poor signal.

    • UK Postcode Boundary API

      Look up any UK postcode or outcode and draw its precise boundary polygon on the map. Area and centroid displayed. Clear with one click. The postcode boundary API is included as standard: perfect for catchment area analysis and site selection. No other UK maps API includes a postcode boundary API at this level.

    • Cycling Layer

      Toggle a dedicated cycling overlay showing cycleways, and colour-coded national, regional, and local cycle routes. Styled separately from the base road network and works across all map themes.

    Five Ways to Integrate. Pick Yours.

    Every paid plan includes the WordPress plugin, the PHP widget, the drop-in JavaScript widget, and full REST API access. Use the plugin if you run a service-based business website. Drop in a single script tag for instant navigation. Call the API directly if you're building something bespoke. Or, if none of those fit, we'll build a custom integration around exactly what you need.

    • Dearthwood Maps for WordPress

      Answer "do you cover my area?" before a customer even has to ask. Add a clean, professional coverage map to any page in minutes. It's a WordPress block, so there's no code to write and nothing to wire up. Perfect for tradespeople, cleaners, mobile mechanics, removals and any service business that lives or dies by its patch.

      Show your coverage two ways: a clean radius circle from your postcode, or a proper service area: just type in the towns and villages you serve and the map draws your region with every place named. Set the size, zoom and your business name, then publish.

      Safe by default: your API key stays on your own server and is never exposed to your visitors' browsers.

    • Your Own Navigation Platform, In One File

      A complete navigation and live-tracking product that's yours to run. One file on your own server gives you five tools in one, with no plugin, no framework and no monthly platform fees on top:

      • Get them to your door: full turn-by-turn navigation with voice, 3D buildings, speed cameras and lane guidance
      • Let customers follow along: they watch their driver approach in real time
      • See your whole fleet: every active driver on one live map
      • Show your coverage: postcode radius circles for your landing pages
      • Quote in seconds: pull distance and drive time on demand for jobs, quotes and texts

      Yours to host: it lives on your own server, so you stay in full control and your API key never reaches your visitors' browsers.

    • Build Anything on the Raw API

      Want full control? Build exactly what you need straight on top of the API, and pay one flat monthly price instead of a per-request bill that grows every time your app gets busier.

      Call any endpoint from your own code and get a simple response back: geocoding, routing, travel-time zones, distance matrix, postcode boundaries and more. It works with any language or stack and mirrors the big mapping APIs, so switching over is usually a quick change, not a rewrite.

      Built for developers: no SDK to install and nothing to keep updated. Just plain requests that work with the tools you already use.

    • A Full Navigation App, One Line of HTML

      Give your customers a complete, mobile-ready navigation experience without building an app. widget.js drops onto any website (WordPress, Shopify, a bespoke CMS or a plain static page) and builds its own interface on the page. No iframe, no plugin, no build step, nothing to host or maintain.

      • Real navigation: turn-by-turn with voice, lane guidance, speed-camera warnings and live GPS following
      • More than one job: delivery-radius circles, live order tracking, and a whole-fleet overview from the same widget
      • Just works: mobile-first, 2D/3D/terrain views, and self-styling so it never clashes with your theme

      Live the same afternoon: if your web person can add a line to a page, it's ready, no coding required.

    • A Custom Mapping Solution, Built Around You

      Not every business fits a plugin or a drop-in widget, and that's fine. If you have a specific workflow, an existing system to connect to, or an idea the standard options don't cover, we'll work with you to design and build a bespoke mapping and location solution around exactly how you operate.

      Custom route planning, delivery and fleet tracking, postcode and service-area logic, distance and travel-time automation, booking and scheduling integrations, or a full location-based platform tailored to your business. If it runs on maps, postcodes or journeys, we can build it.

      Talk it through: Tell us what you're trying to do and we'll tell you straight whether it's doable, how we'd approach it, and what it would cost. No obligation.

    🚚 Built for Real Businesses

    Delivery drivers see turn-by-turn directions. Customers see their order moving in real time. Dispatchers see the whole fleet. Service businesses show their coverage area on a clean radius map. One subscription, one access key, every use case covered. No per-driver fees, no per-map-load charges, no monthly active user counts.

    🔒 UK GDPR Compliant. Your Users' Location Data Stays Private.

    When a user searches an address or requests directions through a Big Tech mapping service, that provider knows. They log it, profile it, and sell against it. Dearthwood Maps is built on UK infrastructure with full UK data sovereignty: no request data leaves the UK, no tracking, no profiling, no third-party analytics. For developers building applications that handle UK user location data, that is not a nice-to-have. Under UK GDPR it is a material consideration. UK-only infrastructure means your data never leaves the UK. Your users' movements are nobody's business but yours, and even you only see what you choose to log.
