No servers to manage, no third-party services in the data path, and no personal data stored. [](LICENSE) Open source under the MIT license. Free to run, forever: the only cost is your own Cloudflare usage, which stays inside the free allowances for most sites. Install it at [traks.dev](https://traks.dev); read the release notes at [traks.dev/changelog](https://traks.dev/changelog). ## Highlights - **Privacy-first** — no cookies, no fingerprinting persistence. Visitors are counted with a Plausible-style daily-rotating hash (`HMAC(secret + date, ip + ua + siteKey)`); raw IP addresses are never stored. - **Realtime by default** — a hot/cold split serves "today" and live views from per-site SQLite Durable Objects in milliseconds, with zero ingest delay. A WebSocket pushes live visitors, pages, referrers, and city-level map dots to the dashboard as they happen. - **Cheap at any scale** — history lives in Apache Iceberg on R2 and is queried with R2 SQL, edge-cached, and scan-minimized. A side project runs for ~$5/mo, 5M pageviews/mo for ~$7, and past that about $4.60 per additional million events (see [cost model](#what-it-costs-to-run)). - **Fully self-contained** — auth is [Better Auth](https://better-auth.com) on D1 (no auth SaaS), the world map is self-hosted (no tile servers), and the dashboard never calls a third party. - **Agent-ready** — analytics are exposed to AI agents via MCP/WebMCP tools, with bot and agent traffic classified and reported alongside human traffic. - **Tiny tracker** — a single `t.js` script tag, served inline from the edge. ## Architecture Fresh data is served from per-site Durable Objects in milliseconds; history is served from Iceberg via R2 SQL. ``` customer site └─ t.js tracker (packages/tracker) │ POST /api/event ▼ collect Worker (apps/platform/collect) ── site-key auth + timezone (D1) │ bot filtering, UA/referrer parsing, │ dual write daily-rotating visitor hash (HMAC) ├────────────────────────────┐ ▼ env.EVENTS.send() ▼ env.LIVE (SiteLiveStore DO) Pipelines stream HOT PATH: per-site SQLite DO │ pass-through pipeline rolling ~48h event window ▼ zero ingest delay, ms queries Iceberg sink → R2 Data Catalog serves: today, realtime table `traks.events` ▲ (zstd parquet, 60s roll, │ auto compaction + │ snapshot expiration) │ ▼ │ COLD PATH: R2 SQL ◄── api Worker (apps/platform/api) ── Better Auth, D1 metadata serves: 7d/30d/90d/1y/all ▲ today/realtime → DO (edge-cached 5-15 min) │ history → R2 SQL │ (DO failure → R2 SQL fallback) web dashboard (apps/platform/web) ``` ### How the pieces fit - **`apps/platform/collect`** — ingest Worker. Validates the site key against D1, filters bots, computes the daily-rotating visitor ID, enriches events with Cloudflare geo data, then **dual-writes**: to the Pipelines stream (durable system of record) and to the site's **SiteLiveStore Durable Object** (hot path). Each write fails independently. - **`SiteLiveStore` DO** — one SQLite-backed instance per site holding a rolling ~48h event window (today plus the previous-day comparison window in any timezone). Today/realtime queries run against local SQLite with millisecond latency. It is also the **realtime push** source: the dashboard opens one authenticated WebSocket (WebSocket Hibernation API) and receives a frame — live visitors, their pages, referrers, countries, and city-level coordinates — whenever a pageview changes the picture, plus a 30s tick so counts decay as visitors leave. Coordinates exist only in this hot window and are never written to Iceberg. - **Pipeline** — pass-through `INSERT INTO SELECT * FROM `; the stream schema lives in `scripts/pipeline-schema.json`. - **`apps/platform/api`** — dashboard API. Site/user metadata in D1 (Drizzle); historical analytics served by R2 SQL over HTTP, cached at the edge. Also serves the dashboard SPA as static assets, so the session cookie is first-party by construction. - **`apps/platform/web`** — the dashboard UI, including the live view with a self-hosted dotted world map generated from Natural Earth data. - **`apps/home`** — the traks.dev site: landing page, docs, and the install wizard. The wizard backend has no database and keeps no record of anyone's instance: instances are discovered live from the user's own Cloudflare account on each sign-in, and a run's progress lives in a Durable Object that wipes itself after a day. - **`packages/tracker`** — the `t.js` tracking snippet. - **`packages/shared`** — event schema (zod), timezone-aware period math, and all R2 SQL query builders. Bucket keys (`date_key`, `hour_key`, `week_key`) are computed at ingest in the site's IANA timezone, so dashboard buckets align with the user's local clock. ## Repository layout ``` apps/ home/ traks.dev site (landing, docs, install wizard) api/ home API Worker web/ home web app platform/ the analytics product collect/ ingest Worker + SiteLiveStore Durable Object api/ dashboard API Worker (auth, R2 SQL, static assets) web/ dashboard SPA packages/ tracker/ t.js tracking script shared/ event schema, period math, R2 SQL query builders eslint-config/ shared lint config typescript-config/ shared tsconfig installer/ release build + upload tooling scripts/ data-platform provisioning, seeding, tracker inlining ``` Monorepo managed with Yarn workspaces + Turborepo.

Open [traks.dev/deploy](https://traks.dev/deploy), sign in with Cloudflare, and the wizard provisions everything into your own account in about two minutes: both Workers, D1, KV, the R2 bucket with Data Catalog, the Pipelines stream and Iceberg sink. Updates and removal are one click each at [traks.dev/update](https://traks.dev/update) and [traks.dev/destroy](https://traks.dev/destroy). traks.dev keeps no record of your instance; every visit rediscovers it from your account. ### Develop Traks The rest of this section is for working on the platform itself. Secrets come from Doppler and nowhere else (see [Development](#development)). The maintainers' projects are `traks-api`, `traks-collect`, and `traks-home`; to run the platform locally you need Doppler projects of your own with those names and the keys listed below. **1. Provision a dev data platform** (once per Cloudflare account; reads `CATALOG_TOKEN` from Doppler `traks-home/prd`): ```sh ./scripts/setup-data-platform.sh dev ``` This creates the R2 bucket, enables the Data Catalog with automatic compaction (128 MB) and snapshot expiration (30 days / keep 5), then creates the stream, Iceberg sink (60 s roll interval for ~1-minute dashboard freshness), and pipeline. Paste the printed stream ID into `apps/platform/collect/wrangler.toml`. **2. Migrate D1 and start the dev servers:** ```sh yarn install yarn workspace @traks/platform-api db:migrate:dev yarn dev # collect :5010, api :5011, web :5012, home :5013/:5014 ``` | Doppler project (dev config) | Keys | | ---------------------------- | ---------------------------------------------------------------------------------- | | `traks-api` | `BETTER_AUTH_SECRET`, `R2_SQL_TOKEN` (Workers R2 SQL Read on the warehouse bucket) | | `traks-collect` | `VISITOR_HASH_SECRET` | | `traks-home` | none required | **3. Seed test data:** ```sh node scripts/seed-events.mjs 500 ``` ### Useful commands ```sh # Ad-hoc queries (token needs Workers R2 SQL Read) WRANGLER_R2_SQL_AUTH_TOKEN= npx wrangler r2 sql query \ "_traks-events-dev" "SELECT COUNT(*) FROM traks.events" # Catalog / maintenance status npx wrangler r2 bucket catalog get traks-events-dev # Pipeline plumbing npx wrangler pipelines list npx wrangler pipelines streams list npx wrangler pipelines sinks list ``` > **Warning:** never delete objects manually in the catalog-enabled bucket — > data/metadata files under the warehouse prefix are Iceberg table state. ## Authentication Auth is [Better Auth](https://better-auth.com) running inside the api Worker — no auth SaaS, no third party. Email + password only; users, sessions, and credential accounts live in D1. **First-run claim:** a fresh instance is unclaimed — `/login` shows a "create your owner account" screen, and the first sign-up claims the instance; sign-ups are rejected server-side after that. The install wizard mints a one-time `CLAIM_TOKEN` worker secret and links to `/login?claim=` so predictable instance hostnames can't be hijacked. **Recovery** (forgot password, no email sending configured): delete the owner's row in `accounts` (+ `sessions`) and re-claim with the same email — site ownership is re-adopted by email. ## What it costs to run Everything runs inside a Cloudflare Workers Paid plan. Billing for Pipelines, R2 Data Catalog, and R2 SQL has been live since 3 Aug 2026; each has a monthly free allowance that most sites never exhaust, so the bill for a small install is essentially the $5/mo Workers Paid base. Cloudflare bills per **event**, and a pageview produces about two (the pageview plus its engagement event), so the tiers below are stated in both. Rates verified 4 Sep 2026; the same model drives the calculator on [traks.dev](https://traks.dev#cost). | Scale | Traffic | Estimated monthly cost | | ------------ | ---------------------------- | ------------------------- | | Side project | 100k pageviews (200k events) | **≈ $5** (base plan only) | | Startup | 5M pageviews (10M events) | **≈ $7** | | Growth | 10M pageviews (20M events) | **≈ $42** | | Scale | 50M pageviews (100M events) | **≈ $410** | Above roughly 6M pageviews the bill is dominated by one line: the hot-path Durable Object writes every event to SQLite, and Cloudflare bills 4 row writes per event over its lifetime (1 row + 2 index entries on insert, 1 on prune; measured with `cursor.rowsWritten`, the figure Cloudflare bills on). That is $4.00 of the ≈ $4.60 each additional million events costs; Worker requests, DO requests, Pipelines and R2 together are the remaining cents. For comparison, hosted analytics vendors publish $16–34 per million pageviews at their top tiers. The hot/cold split is what keeps everything else flat: the always-open "today" dashboard is served by Durable Objects for ~free, historical queries are minimized to single scans (CASE split for current + previous period comparisons) and cached for 5–15 minutes, and egress is always $0. Full rate table | Component | Rate | Monthly free allowance (paid plan) | | ---------------------------------------- | -------------------------------------------------------------------------------------------------------------------- | ---------------------------------- | | Workers Paid base | $5/mo | 10M requests, 30M CPU-ms incl. | | Workers requests / CPU over included | $0.30/M requests / $0.02/M CPU-ms | — | | Durable Objects requests | $0.15/M | 1M | | DO duration | $12.50/M GB-s (idle objects are not billed) | 400k GB-s | | DO SQLite writes / reads / storage | $1.00/M rows / $0.001/M rows / $0.20/GB-mo | 50M / 25B rows / 5GB | | Pipelines: ingest → transform → delivery | free → $0.04/GB → $0.06/GB (Parquet), uncompressed bytes; the pass-through `INSERT … SELECT *` counts as a transform | 50GB per dimension | | R2 storage | $0.015/GB-mo | 10GB | | R2 Data Catalog operations | $9.00/M | 1M | | Catalog compaction | $0.005/GB + $2.00/M objects | 10GB + 1M objects | | R2 SQL | $2.50/TB scanned (10MB min/query) | 10GB scanned | ## Cloudflare data platform status R2 Data Catalog, R2 SQL, and Pipelines are still **open beta** (as of Sep 2026) but production-trending: pricing is published and billing has been on since Aug 2026, the catalog has a dedicated dashboard, GraphQL metrics, and Terraform support, and R2 SQL supports JOINs, CTEs, CASE, window functions, set operations, exact `COUNT(DISTINCT)`, and ~200 functions. Known platform gaps this codebase works around: catalog sinks have no user-defined partition spec and cannot be modified or re-attached to an existing table (so a sink's roll interval is fixed for the table's lifetime), stream schemas are immutable, R2 SQL has no timezone conversion and no metrics dataset for bytes scanned, and every R2 SQL query bills a 10 MB minimum. Known limits of this design, from Cloudflare's published numbers: - **One Durable Object per site is the per-site ceiling.** Cloudflare rates a single object at roughly 200–500 requests/s for operations that write storage, and a pageview costs about two DO requests, so one site sustaining 150–250 pageviews/s (a front-page spike, or roughly 10M+ pageviews/month with peaks) saturates its object. The failure is graceful: the write is counted in the `live_write_failed` metric and the dashboard falls back to R2 SQL, but "today" undercounts until traffic drops. Sharding a site across several objects (keyed by site plus shard, fan-in on read) is the planned path if a real site gets there. - **Pipelines beta limits per account:** 20 streams, 20 sinks, 20 pipelines, and 5 MB/s ingest per stream (about 6k events/s at Traks' record size). Each instance uses one of each. - **The Workers Cache API is only functional on custom domains.** Wizard installs default to workers.dev, where the per-colo cache layer is a no-op and the KV result cache does all the work. Instances on a custom domain get both layers.
