# LaunchDarkly > launchdarkly.com | Developer services; 1 record: free tier, limits, identity cost and evidence. HTML https://fshy.ajam.dev/p/launchdarkly/ | JSON https://fshy.ajam.dev/api/v1/entity/launchdarkly.json | how to read a record: https://fshy.ajam.dev/llms-full.txt ## LaunchDarkly - `dev-services/launchdarkly` | qualifies-with-caveat | evidence documented | binding volume-quota | category hosted feature flags, experimentation and observability | tier Developer - needs card no, phone unknown, ID no, institution no | verified 2026-11-02T00:37:55.413Z (live) | stale on 2026-12-03 - url https://launchdarkly.com/pricing/ - free tier: Developer: USD 0 a month forever, no credit card; unlimited feature flags and seats, 5 service connections and 1K client-side MAU a month, 100K experimentation MAU, 10M logs and 10M traces, 5K session replays and 5K errors, 5K AI runs a month; 1 project and 3 environments | unit: mixed | read on: 2026-10-30 | source: [1] | note: The allowance is counted in service connections (one server-side SDK connected to one environment for a month), client-side MAU (each unique client-side user or device), log lines, trace spans, session replays, errors and AI runs; no single unit term fits. Sign-up starts a 14-day trial with Enterprise features that converts to Developer. When usage keeps exceeding the Developer entitlements the plan converts to read-only mode. - per-object cap: unverified: no flag or payload size limit is stated on the pages read - retention: Logs, traces, session replays and errors are stored one month; AgentControl run and eval data stays 14 days | source: [1] - egress: not applicable: flag evaluations reach the SDKs over routes that are never rate limited; no traffic allowance is published | metered: no | source: [2] - identity: email | detail: The sign-up form asks for first name, last name, email and password, or a GitHub sign-in, and states no credit card is required; it starts a 14-day trial that continues on the free Developer plan. The GitHub route shows a Complete profile screen for First name, Last name, Work email and Organization, then sends an email to verify the account. Whether a later step asks for a phone number is unverified: behind a sign-up. - interface: rest - limits: - volume-quota (binding): 5 service connections and 1K client-side MAU a month [1] - volume-quota (binding): 10M logs and 10M traces a month; 5K session replays and 5K errors a month; 5K AI runs a month [1] - write-gated: usage that keeps exceeding the Developer entitlements converts the plan to read-only mode [3] - retention-clamped: logs, traces, session replays and errors stored one month; AgentControl data 14 days [1] - limits note: 1 project and 3 environments on Developer. REST API rate limits are not published; LaunchDarkly returns them in response headers. - binding note: Each server-side SDK in each environment uses one of the 5 service connections a month, so server-side use meets that count first; client-side apps meet 1K MAU. Continued excess turns the plan read-only. - interface detail: REST API at https://app.launchdarkly.com/api/v2 with personal or service access tokens (a GET /api/v2/projects without a token answered 401); SDK keys, mobile keys and client-side IDs cannot call the REST API; an OpenAPI specification is published. - endpoint: part of interface detail - tooling: 30 SDKs (13 client-side, 13 server-side, 4 edge), the Relay Proxy, or any HTTP client against the REST API with an access token. - composes with: Feature flags for a few server-side services on free compute, with client-side flags for up to 1K MAU a month. - reliability: Usage above the Developer entitlements is warned and then turns the plan read-only; Developer support is the Discord community. - notes: Foundation is pay as you go after a 14-day trial: USD 10 per service connection a month and USD 8.33 per 1K client-side MAU a month billed yearly. - evidence note: Every value is quoted from the first-party pricing page, plan and billing docs, REST API overview and sign-up page; the REST API host was probed and answered 401 without a token. A flag evaluation through an SDK key on a Developer account would move it to measured. - evidence: - [1] 2026-10-30: Developer needs no credit card | capture: sha256:96fbff66a5dc31d47bd8c2e5c4ce017d3a80974cc00a9f1e56a2b71c36fb48ba | quote: [Get started free](https://app.launchdarkly.com/signup) No credit card required - [1] 2026-10-30: Developer is USD 0 a month forever | capture: sha256:96fbff66a5dc31d47bd8c2e5c4ce017d3a80974cc00a9f1e56a2b71c36fb48ba | quote: $0/ mo, forever - [1] 2026-10-30: Developer includes 5 service connections and 1K client-side MAU a month | capture: sha256:96fbff66a5dc31d47bd8c2e5c4ce017d3a80974cc00a9f1e56a2b71c36fb48ba | quote: 5 service connections and 1K client-side MAU /mo - [1] 2026-10-30: what a service connection and an MAU are | capture: sha256:96fbff66a5dc31d47bd8c2e5c4ce017d3a80974cc00a9f1e56a2b71c36fb48ba | quote: A service connection is one server-side SDK connected to one environment for a month.
