Highlight.io
Pros
- + One stack for session replay, errors, logs, and traces with OpenTelemetry-based instrumentation and cross-signal correlation
- + Genuinely usable free tier: 500 monthly sessions and up to 15 seats at $0/month
- + Fully self-hostable from the public repository (Docker hobby stack), keeping session data on your own infrastructure
- + Strong docs for a vendor: architecture notes, self-hosting guides, changelogs, telemetry disclosure
- + Acquired into LaunchDarkly with the founders leading observability there, so the hosted product has a defined continuation path
Cons
- - Standalone product is being absorbed: highlight.io serves LaunchDarkly's site and cloud accounts are being migrated
- - Open-source repository's final community support date is still unannounced, so self-hosters face an uncertain maintenance horizon
- - Thin pricing ladder: nothing between the free tier and $800/month Business, with per-type usage overages and conflicting published quotas
- - No published infrastructure SLA, region map, or uptime record for the hosted product
- - Self-hosting means operating a multi-service stack (database, queue, collectors) with no managed middle tier
Elastic Observability
Pros
- + One search engine for logs, metrics, traces, synthetics and RUM with a single query language
- + Open source again (AGPLv3/SSPL/ELv2 since August 2024) — self-managed deployments are free
- + Cheap volume-tiered ingest on serverless: from $0.07/GB (Logs Essentials) with $0.017/GB-month retention
- + Data tiers and searchable snapshots keep long retention affordable while staying queryable
- + 50+ cloud regions on AWS, Google Cloud and Azure with FedRAMP High, SOC 2 Type II, ISO 27001, HIPAA, PCI DSS
Cons
- - Genuine learning curve: query DSL, index lifecycle, shard and mapping decisions
- - Self-managed operation (JVM tuning, upgrades, snapshots) is a real operational project
- - Meters run on enriched pre-compression volumes and "as low as" rates are volume-tiered — bills surprise the unprepared
- - Support priced as a percentage of spend (5% Gold, 10% Platinum, 15% Enterprise on top of consumption)
