Let’s be honest: Promtail was great when we were all just starting with Loki, but the “one agent per task” era is dying. In 2026, nobody wants to manage five different collectors for logs, metrics, and traces. We need tools that don’t choke on multi-cloud complexity and, frankly, tools that don’t eat up half our CPU just to move strings around.
1. AppFirst
AppFirst was built because its founders grew tired of watching developers waste countless hours managing infrastructure instead of focusing on building actual products. Users simply specify what their app needs-CPU, memory, a database, networking rules, or a Docker image – and AppFirst automatically provisions everything across AWS, Azure, or GCP. There are no Terraform files, no YAML configurations, and no manual VPC setup required. The platform handles security boundaries, tagging, best practices, and all related details.
Observability is built-in from the very beginning: every environment deployed comes with logging, monitoring, and alerting pre-configured and ready to use. Users gain centralized views of costs broken down by application and environment, along with complete audit trails of every infrastructure change. AppFirst offers both SaaS deployment and self-hosted options, depending on what best suits the customer’s needs.

מַסְקָנָה
Picking the right log collector boils down to what your setup actually looks like and where the pain points sit. Some tools stay super lightweight and just grab logs from containers or files without much fuss, while others bundle in heavier processing, metrics, or even full pipelines right out of the gate. A few lean hard into open standards like OpenTelemetry, others stick close to specific ecosystems, and some go the agentless route entirely.
At the end of the day, ditching Promtail usually means chasing more flexibility, lower overhead, or tighter integration with the rest of the stack. Most modern options handle the basics reliably – tailing files, surviving restarts, shipping to multiple backends – but the real differences show up in configuration hassle, resource footprint, and how easily they play with whatever else runs in the environment. Test a couple in a staging setup, see what clicks, and go with the one that keeps logs flowing without turning into another maintenance burden. Simple as that.
