## Datadog (free)

- `dev-services/datadog` | qualifies-with-caveat | evidence documented | binding retention-clamped | category infrastructure monitoring (hosted observability platform) | tier free
- needs card no, phone no, ID no, institution no | verified 2026-10-31T00:43:09.670Z (live) | stale on 2026-12-01
- url https://www.datadoghq.com/pricing/
- disagrees on identity_kind: `dev-services/datadog` says email, `dev-services/datadog-open-source` says institution
- disagrees on verdict: `dev-services/datadog` says qualifies-with-caveat, `dev-services/datadog-open-source` says fails-identity
- free tier: Free tier after the 14-day trial: up to five Basic hosts with 1-day metric retention at no cost; LLM Observability separately has a free tier of up to 40K LLM spans per month with 15-day retention and no credit card | unit: mixed | metered on: object-count | read on: 2026-10-31 | source: [1] | note: The infrastructure allowance is counted in hosts, a unit the vocabulary lacks. Container monitoring is not available for Basic hosts. The trial lasts 14 days and monitors any number of servers.
- per-object cap: unverified: the pricing, sign-up and API pages quoted name no payload limit
- retention: 1-day metric retention on the Free tier; 15-day retention for LLM spans on the LLM Observability free tier | days: 1 | source: [1]
- egress: not stated: the pricing page names no charge for reading data back on the Free tier | metered: no | source: [1]
- identity: email | detail: The sign-up form marks Business Email, Full Name, Company and Password as required, with a data region that cannot be changed later; Phone is not starred among the required fields, so no phone is required; Google sign-up is offered; the form has no card field. Whether an address at a public mail domain passes as a business email is unverified.
- interface: rest
- limits:
  - volume-quota: up to five Basic hosts (a count of hosts, not bytes) [1]
  - retention-clamped (binding): 1-day metric retention [1]
- limits note: Container monitoring is not available for Basic hosts.
- binding note: Metrics older than one day are gone on the Free tier, so the five hosts give a live view and no history.
- interface detail: The Datadog API is an HTTP REST API authenticated with an API key in the DD-API-KEY header, and for some endpoints an application key in DD-APPLICATION-KEY
- tooling: the Datadog web app, the REST API and its official client libraries; host metrics come from the Datadog Agent and cloud integrations
- composes with: Host metrics for up to five machines with a one-day window: a live view of free VMs, not a history.
- reliability: no reliability event recorded
- notes: The open source programme recorded as compute/datadog is a different offer, decided on the project's team.

## Datadog (Compute)

- `compute/datadog` | fails-identity | evidence documented | binding write-gated | category infrastructure monitoring (hosted observability platform), programme for open source projects
- needs card no, phone no, ID no, institution yes | verified 2026-10-31T06:50:57.864Z (live) | stale on 2026-12-01
- url https://www.datadoghq.com/partner/open-source/
- free tier: 'Use this form to apply for access to Datadog at no cost. We evaluate applications on a case by case basis.' The stated limits are qualitative: 'The number of hosts (or other types of compute units) and telemetry events may be limited.' | unit: none | metered on: unstated | read on: 2026-10-31 | source: [1] | note: No amount is published: hosts and telemetry events may be limited, and applications are evaluated case by case.
- per-object cap: unverified: the programme page names no payload limit | source: [1]
- retention: unverified: the programme page names no retention period | source: [1]
- egress: not stated | metered: no | source: [1]
- identity: institution | detail: The application form requires full name, email, project name, project website or repository, an open source licence and a description, with no card or phone field; eligibility rests on the project's team (its regular contributors and maintainers at different companies), which a single maintainer cannot meet.
- interface: rest
- limits:
  - write-gated (binding): the project must be non-commercial under an approved open source licence, at least 1 year old, with at least 5 regular contributors and at least 2 maintainers working for different companies; applications are evaluated case by case [1]
  - volume-quota: the number of hosts and telemetry events may be limited; the programme page publishes no figure [1]
- limits note: The monitored infrastructure and applications must directly support the project, so instances of an open source project run for other uses are out of scope.
- binding note: At least 5 regular contributors and at least 2 maintainers at different companies are required, so a project with one maintainer cannot apply.
- interface detail: The Datadog API is an HTTP REST API; its scope under the programme is not stated on the programme page
- tooling: the Datadog web app and the Datadog REST API
- composes with: For a project that meets the team conditions, Datadog at no cost for the infrastructure that runs the project; anyone else has the self-serve Free tier of up to five Basic hosts recorded as dev-services/datadog.
- reliability: unverified: the programme page names no enforcement past its host and telemetry limits
- notes: Kept apart from dev-services/datadog, which records the self-serve Free tier of up to five Basic hosts with 1-day metric retention: the open source programme is applied for and evaluated case by case, publishes no host or event figure, and is open only to a non-commercial project at least 1 year old with at least 5 regular contributors and maintainers at two or more companies, so the two are different offers.
- extras:
  - facets.class: vendor-oss-credits
  - facets.free_tier_kind: recurring-credit

- composes with: For a project that meets the team conditions, Datadog at no cost for the infrastructure that runs the project; anyone else has the self-serve Free tier recorded as dev-services/datadog.
