# gleam vs openobserve

gleam and openobserve share 5 technologies: Tokio, pulldown-cmark, zip, tracing, and tracing-subscriber. Both are written in Rust.

- [gleam-lang/gleam](https://seerepo.com/r/gleam-lang/gleam): ⭐️ A friendly language for building type-safe, scalable systems!
- [openobserve/openobserve](https://seerepo.com/r/openobserve/openobserve): Open source observability platform for logs, metrics, traces, RUM (web, android, ios), Session replay, pipelines, SLO and LLM observability. A sophisticated, simple and highly performant alternative to Datadog, Splunk, and Elasticsearch with 140x lower storage costs and single binary deployment.

## What they share and what sets them apart

- In common: Tokio, pulldown-cmark, zip, tracing, tracing-subscriber
- Only in gleam: rpassword
- Only in openobserve: axum, axum-extra, db, wal, arrow, sqlx, async-nats, hashlink, lru, aws-sdk-sns, Svix, tower, Vite, Vue, vue-router, sea-orm, hmac, jsonwebtoken, argon2, hkdf, OpenAI, tiktoken-rs, parquet, csv, image, log, opentelemetry, tracing-opentelemetry, prometheus, tracing-appender, console-subscriber, env_logger, opentelemetry_sdk, opentelemetry-otlp, tracing-log, Tailwind CSS, Reka UI, echarts, vue-flow, TanStack, vue-draggable-next, Leaflet, monaco-editor, D3, d3-scale, dompurify, marked, highlight.js, js-yaml, json-2-csv, Zod

## Side by side

| | gleam | openobserve |
|---|---|---|
| Size | 236,829 lines written, 140 code files | 3,634,762 lines written, 5,454 code files |
| Who writes it | 0% of its commits signed by AI | 5.2% of its commits signed by AI. With Claude Code, GitHub Copilot, Cursor, and CodeRabbit |
| Activity | Last push November 3, 2026, 11,770 commits, 22,021 stars | Last push November 4, 2026, 8,407 commits, 22,797 stars |
| Tests | 148 test files. 44.3% of its code files have a test that imports them | 4,043 test files. 49.9% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
