Last9 vs Bruno
Side-by-side comparison of AI visibility scores, market position, and capabilities
Last9 is a high-cardinality observability platform with a storage engine built for modern microservices, letting SRE teams retain full-dimensional metrics without cost explosions.
About
Last9 is an observability platform engineered for high-cardinality metrics at the scale that modern microservices architectures generate. Most time-series databases degrade in query performance and cost efficiency as cardinality increases — a fundamental limitation that forces teams to drop dimensions, aggregate prematurely, or pay disproportionate infrastructure costs as their systems grow. Last9 addresses this with a storage engine built from the ground up for high-cardinality workloads, allowing SRE and platform teams to retain full-dimensional metrics without the cardinality-driven cost explosions that occur with Prometheus-based solutions or legacy commercial monitoring platforms.
Open-source offline-first API client with git-native Bru file storage; solo-founded, declined 8 VC offers, competing with Postman and Insomnia for developers seeking privacy-respecting local API testing tooling.
About
Bruno is an open-source API client and testing tool — a lightweight, offline-first, git-friendly alternative to Postman and Insomnia — enabling developers to explore, test, and document APIs with collections stored as plain-text Bru files in the project filesystem rather than in cloud-synced proprietary formats. Created by a solo founder in 2022 and growing to a 9-person team by late 2024, Bruno operates with an unusual philosophy: the founder publicly declined 8 venture capital offers to preserve product freedom and build toward profitability, with the core Bruno client remaining free and open-source (MIT license) while the Golden Edition provides enterprise features for commercial revenue. Pro and Ultimate paid editions launched in 2024.
