# Snowflake / Discord ID Bit Decoder Decode 64-bit Snowflake-style IDs for Discord, Twitter, Mastodon, Sonyflake, Instagram, or a custom bit profile. Extract timestamp, worker/process/machine, sequence fields, align platform epochs, and infer a Discord shard when a shard count is supplied. > Canonical page: https://elysiatools.com/en/tools/snowflake-discord-id-bit-decoder - **Category:** Development - **Keywords:** snowflake, discord, id decoder, bit fields, twitter snowflake, sonyflake, mastodon, instagram id, shard, bigint ## Overview Snowflake / Discord ID Bit Decoder analyzes 64-bit Snowflake-style IDs for Discord, Twitter, Mastodon, Sonyflake, Instagram, or a custom bit profile. It extracts timestamp and identifier fields, applies the selected epoch, and can infer a Discord shard when a shard count is provided. ## Inputs - **Snowflake ID** (text): e.g. 109580041603153152 - **平台** (select) - **Discord 分片数（可选）** (number): e.g. 8 - **自定义 Epoch（ISO 日期或 Unix 毫秒）** (text): e.g. 2015-01-01T00:00:00Z - **自定义时间戳单位** (select) - **自定义字段 JSON（低位在前）** (textarea): \[{"name":"sequence","bits":12},{"name":"worker","bits":5},{"name":"timestamp","bits":47}\] ## When to use - Inspect the creation time and bit fields inside a Discord or other Snowflake-style ID. - Compare IDs from platforms that use different epochs or field layouts. - Analyze a private Snowflake deployment with a custom epoch and low-bit-first field definition. ## How it works - Enter the 64-bit Snowflake ID in the required input. - Select Discord, Twitter, Mastodon, Sonyflake, Instagram, or Custom as the platform profile. - Optionally provide a Discord shard count or configure a custom epoch and timestamp unit. - For a custom layout, enter a JSON field list ordered from the least significant bits first, then review the decoded HTML result. ## Use cases - Discord bot development teams can inspect ID timestamps and estimate shard assignment. - Backend engineers can verify worker, process, machine, and sequence fields in distributed identifiers. - Developers maintaining private Snowflake deployments can test custom bit layouts against a selected epoch. ## Frequently asked questions ### Which ID formats does the decoder support? It supports Discord, Twitter, Mastodon, Sonyflake, Instagram, and custom Snowflake-style bit profiles. ### Can it decode large 64-bit IDs without losing precision? Yes. The tool is designed to parse 64-bit Snowflake-style IDs without precision loss. ### What does the Discord shard count do? When supplied, the shard count lets the tool infer a Discord shard for the decoded ID. ### How do I define a custom profile? Select Custom, provide an epoch, choose the timestamp unit, and enter a JSON field list ordered from the least significant bits first. ### Which timestamp units are available for custom profiles? Custom timestamps can use milliseconds, 10-millisecond units, or seconds. ## Related tools - [Distributed Trace Decoder & Waterfall Visualizer](https://elysiatools.com/en/tools/distributed-trace-decoder-waterfall-visualizer): Decode Jaeger, Zipkin, or OpenTelemetry trace JSON and render span timing, dependencies, and error hotspots as an interactive waterfall report - [Structured Log Analyzer](https://elysiatools.com/en/tools/structured-log-analyzer): Detect common log formats, extract core fields, infer field types, and export parsed logs as JSON, CSV, or SQL inserts - [package.json Dependency Auditor](https://elysiatools.com/en/tools/package-json-dependency-auditor): Audit a package.json for dependency hygiene, version-range quality, and optionally inspect a transitive dependency tree from package-lock.json or yarn.lock.
