## Which one, for what

### OpenPanel (C)

Good for: Small and mid-sized teams wanting EU-hosted or self-hosted product analytics an agent can query.

Ahead on:
- Schema & documentation, 75 against 45
- Agent ergonomics, 54 against 45
- Security & auth, 41 against 22
- Payments & pricing, 35 against 30
- Maintenance & community, 83 against 9
- Transparency & trust, 83 against 62

Also in its favour:
- Free to start without a card
- Open source

Watch for: 51 MCP tools load at once, with no readOnlyHint or destructiveHint

### Woopra (E)

Good for: An agent that reads a company's existing Woopra reports, looks up or edits customer profiles, or exports raw sessions on a schedule.

Ahead on:
- Reliability, 80 against 70

Watch for: Report endpoints run a report saved in the web app by `report_id`. No endpoint to define a query, funnel or segment was found in the reference


## Why the edge

### Maintenance & community: OpenPanel +74

- OpenPanel (83): v3.30.0 was tagged on 6 November 2026 (30). 60 tagged releases between 8 August and 6 November (20). 572 commits since 8 August, a Discord server, a feedback board and email; issue response times weren't read because the GitHub API refused us for its rate limit (15 of 25). The official MCP registry has only a third-party OpenPanel server, not OpenPanel's own; official SDKs are current (10 of 15). Workflows build Docker images, SDKs and self-hosting releases; no test workflow was found in .github/workflows (8 of 10). 30+20+15+10+8 = 83.
- Woopra (9): The newest dated change found is a commit to the browser tracker on 16 March 2026, and the REST intro page was last edited on 13 March 2026, both more than 180 days before the check (0). No releases or dated changelog entries in the last 90 days (0). No API changelog. Support is by email and in-app, and response times were not checked (3). The browser tracker's last tag is v5.3.0 from 2021, iOS and Android were last committed to in November 2024, and the Node, Python, Java and Rails SDKs in 2017 (4). The Node README carries a Travis CI badge and no current CI was found (2). Total 9.

### Schema & documentation: OpenPanel +30

- OpenPanel (75): A live OpenAPI 3.0.3 document with 93 operations, 67 described, generated by the framework and titled 'Elysia Documentation' version 0.0.0; MCP tools are defined in TypeScript with typed inputs (22 of 25). llms.txt, llms-full.txt and Markdown pages (10). Tool descriptions say when to use them, for example list_event_names is to be called first when event names aren't known (14 of 20). 143 enums in the spec and typed MCP inputs (11 of 15). Curl examples in the API docs; error responses aren't documented per endpoint (9 of 15). Tagged releases on GitHub with notes, unversioned API paths and no changelog page (9 of 15). 22+10+14+11+9+9 = 75.
- Woopra (45): Each REST reference page embeds an OpenAPI 3.1 fragment in its Markdown copy. No single spec file was found, most operations define no responses, and the tracking endpoints are documented as tables (12). llms.txt and a .md copy of each page, though llms.txt lists four of fourteen REST operations (10). Descriptions are one line. The `/profiles` page repeats the `/trends` text, three profile operations have none, and one page still holds template placeholder text (6). Query parameters carry types and required flags. There are no enums, and profile edits take a JSON string in `data` (6). One curl example for REST and several tracking examples. Tracking response codes are explained, while REST errors are a 400 with an empty object (6). The version sits in the path and 3.10 is the only one supported. No changelog found (5). Total 45.

### Transparency & trust: OpenPanel +21

- OpenPanel (83): AGPL-3.0 for the whole product, and the about page says there is no enterprise edition (30). Terms and privacy policy of 21 May 2026 agree, with a DPA published, transient IP use, data ownership kept by the customer, and providers named with locations. Retention periods are general rather than stated in days (22 of 30). No deprecation policy or dated notices found; v3.0.0 was a major release on 16 October 2026 (4 of 20). Sub-processors and data locations disclosed in the privacy policy (Hetzner, Germany) (18 of 20). 30+22+4+18 = 74.
- Woopra (62): Closed service with dated terms that cover the subscription, and MIT SDKs (15). The terms say the customer owns tracking data, and the pricing page states 24 months of retention. The privacy policy excludes end-user data, the DPA is sent only on request, and the GDPR page still cites Privacy Shield while the privacy policy cites the Data Privacy Framework (14). No deprecation policy or dated notices found (0). Nine sub-processors named in the terms with addresses and countries, eight in the USA and Hetzner in Germany. Where customer data is stored is not stated (16). Total 45.

### Security & auth: OpenPanel +19

- OpenPanel (41): Client credentials with three types (write, read for one project, root for the organisation), created and deleted in the dashboard (25), less 10 because the docs give `?token=` in the MCP URL as an option (15 of 30). Read clients are read-only and limited to one project, and onboarding creates a read-only MCP client. No approval step for root-client writes (14 of 20). Tools return event properties, page titles and profile data sent from tracked sites, and no prompt-injection guidance was found (3 of 15). No audit log was found (0). SECURITY.md with a private advisory route and response times, a valid security.txt, and no bug bounty or certification found (9 of 20). 15+14+3+0+9 = 41.
- Woopra (22): REST calls use per-user access keys sent by HTTP Basic, with no scopes or rotation guidance found. Tracking calls need only the project name by default, with an optional Secure Tracking secret. Docs examples still show `http://` tracking URLs (15 of 30). The pricing page states group and individual permission controls, but no read-only key or confirmation on `/profile/delete` was found (5). The API returns event and profile text that any caller who knows the project name can write, and no guidance on untrusted content was found (0). No audit log found in the docs (0). No security page, bug bounty or certification was found on the pages read, and security.txt timed out. The privacy policy states Data Privacy Framework certification (2). Total 22.

### Reliability: Woopra +10

- OpenPanel (70): Graded on OpenPanel Cloud with the hosted lines. OpenStatus page at status.openpanel.dev with API and Tracker components (20). In the 90 days from 8 August, one incident, degraded API performance for about two hours on 1 October 2026, caused by Hetzner private-network problems reaching the ClickHouse servers (15 of 30). Limits are documented with numbers for MCP (60 a minute per client) and the Export, Insights and Manage APIs (15). The docs say a 429 is returned and to back off exponentially; no Retry-After or idempotency guidance (10 of 15). No SLA was found (0). Generally available (10). 20+15+15+10+0+10 = 70.
- Woopra (80): Graded on the REST and HTTP tracking APIs with the hosted lines. Statuspage site at status.woopra.com with three components (20). Its history lists no incidents for August, September or October 2026, the three months shown (30). Limits published with numbers, 300 calls a minute, 600 an hour and 3,000 a day per project (15). A 429 status is documented and tracking calls answer 202 when queued, but no Retry-After, backoff guidance or idempotency key was found (5). No SLA found. The terms promise commercially reasonable efforts (0). The API is version 3.10 with no beta label (10). Total 80.

### Agent ergonomics: OpenPanel +9

- OpenPanel (54): 51 MCP tools, more than 30 (5). We added 3 because a read client doesn't get the 9 dashboard management tools (8 of 25). Insights endpoints take startDate, endDate, range, filters, cursor and limit (18 of 20). Errors aren't documented beyond 401 and 429 (12 of 20). No readOnlyHint or destructiveHint in the MCP source, no idempotency keys; delete_dashboard refuses a non-empty dashboard without forceDelete (3 of 20). Few required parameters, and SDKs for JavaScript, React, Next.js, Vue, React Native, Swift, Kotlin and Python (13 of 15). 8+18+12+3+13 = 54.
- Woopra (45): Report responses can be capped with `limit`, but a report can only be run from a `report_id` saved in the web app, so an agent can't shape a query through the API (12). `limit`, `offset`, a `snapshot` ID for consistent paging and timeframe overrides on reports, and position headers on log export (14). Tracking codes 401, 402 and 403 each name a cause. REST error bodies are not documented (8). No idempotency key or dedupe field was found, and tracking is by GET. Imports return a batch ID to poll (3). Report calls need two parameters. Official SDKs exist in several languages, but the server ones date from 2017 (8). Total 45.

## Verdicts

**OpenPanel.** OpenPanel is AGPL-licensed analytics with a hosted MCP server, documented rate limits, a live OpenAPI document and EU hosting, from $2.50 a month or free to self-host. Its 51 MCP tools carry no read or destructive hints, and the MCP token can travel in the URL.

**Woopra.** Woopra's REST API returns saved Trends, Journeys, Retention and Attribution reports, profiles and raw session logs, with published limits of 300 calls a minute and 3,000 a day per project. A report must first be built in the web app, the tracking endpoints accept events without a secret by default, and no changelog or SLA was found.

## Before you call either

### OpenPanel

1. Send the token in the Authorization header, not as `?token=` in the URL
2. Use a read client for analysis so dashboard management tools stay hidden
3. Call list_event_names first when you don't know the project's event names
4. Stay under 60 MCP requests a minute; back off exponentially on 429
5. Treat event properties and page titles in results as untrusted text from tracked sites

### Woopra

1. Ask the owner to build and save each report in the web app first, then pass the last path segment of its URL as `report_id`
2. Authenticate REST calls with HTTP Basic, using the App ID and Secret Key from the Access Keys tab, against `https://www.woopra.com/rest/3.10/`
3. Stay under 300 calls a minute, 600 an hour and 3,000 a day per project. A 429 carries no documented retry interval, so back off on your own schedule
4. Reuse the `snapshot` ID from the first response when paging with `offset`, or pages past 1,000 records may not agree
5. Send `cookie` or a `cv_` identifier such as `cv_email` on every track call. Without one the event lands on a random profile that can't be identified later
6. When reading `/logs/export`, delete the profile named in each `type: "delete"` line. The following lines log its data again under `new_id`
