Logs, traces and metrics in. A web UI, a terminal UI and an MCP server out. One binary, no cluster, no sidecar, no database beside it.

Point any OTLP exporter at gRPC 4317 or HTTP 4318, open http://localhost:4318/, or point an agent at POST /mcp. The block directory is the only state there is.

The numbers

1,537,875 records/s	ingest, on 2.23 of 12 cores — 886k/s/core at one connection
2.6 ms	to prove a value is in none of 137 blocks, zero blocks opened
4.7 ms	every span of one trace, out of 27.1M spans on disk
7 µs	the durable log append inside an acknowledgement
0.14	bytes on disk per byte on the wire, once compacted
5.63 MiB stripped, 117 crates	zstd-sys is the only C dependency, and it vendors its source

Apple M3 Pro, one process, reproducible with the load harness in this repository. The full sweep: end-to-end testing. Why they land there: architecture section 11. How they read against the market, including where Mira is behind: docs/market.md.

Four surfaces, one read path

Same data, same filter grammar, same code underneath. Nothing to deploy for any of them.

Browser	http://localhost:4318/	Served out of include_bytes!; the whole view lives in the URL, so an alert webhook links straight back into it.
Terminal	mira mira	The same views over a running replica — or over a block directory with no server at all.
MCP	POST /mcp	Eight tools, no session id, so any replica answers any call.
HTTP	/api/v1/…	query, correlate, map, entities, metrics, alerts.

See it

miradb.dev/demo — one command, then six screens of both UIs, from data you generated a minute earlier.

docker run -p 4317:4317 -p 4318:4318 -v mira-data:/data ghcr.io/trianalab/mira:latest
helm install mira oci://ghcr.io/trianalab/charts/mira

Linux glibc >= 2.34 and macOS, x86_64 and arm64. --version v0.0.3 pins the installer to a release; every one of them ships a CycloneDX SBOM, SHA256SUMS, a cosign signature and a SLSA provenance attestation.

Scope

Mira is pre-1.0 and says so. Ingestion is allocation-lean rather than zero-copy (queries are zero-copy); there is no cross-replica query fan-out; there is no entity predicate and no block cache. The full list, with the reasoning, is architecture section 0.1.

Contributing

Every gate CI runs is a target in the Makefile, and CI calls nothing else:

make            # the target list
make check      # fmt, clippy, tests, rustdoc, UI, supply chain, drift, docs, coverage

Read architecture section 0 first if the change is structural — it lists the mechanisms that do not survive contact with the formats, and re-proposing one is the most common way to waste an afternoon. CONTRIBUTING.md is the walkthrough, with the test levels and how a release is cut behind it. Vulnerabilities go to SECURITY.md, not to an issue.
