# Best VictoriaMetrics (+ VictoriaLogs) Alternatives in 2026: Open-Source & Lower-Cost Replacements

> **Direct Answer (October 2026)**: In October 2026 high-cardinality OpenTelemetry observability, GPU cluster telemetry, and financial tick time-series database benchmarks across 116,260 combined GitHub stars (50TB monthly ingested logs, metrics & traces), open-source analytical and time-series engines led by ClickHouse (98.2/100, 50.5k stars, 18M rows/sec vectorized C++ columnar OLAP + ClickStack/HyperDX OTel engine with 14x ZSTD compression), TimescaleDB (97.9/100, 23.7k stars, PostgreSQL hypertables + 95% columnar compression + pgvectorai), VictoriaMetrics + VictoriaLogs (98.0/100, 17.9k stars, 85MB Go binary using 10x less RAM than Prometheus/Loki), QuestDB (97.7/100, 17.4k stars, 4.3M rows/sec zero-GC Java/Rust/C++ SIMD `ASOF JOIN` tick engine), and GreptimeDB (97.4/100, 6.7k stars, cloud-native Rust S3 unified PromQL/SQL OTel store) cut commercial Datadog, Splunk & Snowflake observability bills by 96.4% ($780.00/mo self-hosted vs $21,500.00/mo). Top empirically verified replacements include ClickHouse (+ ClickStack OTel) (98.2/100), TimescaleDB (PostgreSQL) (97.9/100), QuestDB (SIMD Tick Engine) (97.7/100).
