5 Arize Phoenix Alternatives for Permissive Self-Hosting in 2026
Arize Phoenix markets itself as "fully open source, no feature gates" - but the server repo is Elastic License 2.0, source-available, not OSI open source. If you need a genuinely permissive self-host, here are five alternatives matched to why teams leave.
5 DeepEval Alternatives That Cut the LLM-Judge Bill in 2026
DeepEval is pytest for LLM apps, and the OSS framework is free under Apache-2.0 - but nearly every metric is LLM-as-judge, so big suites run slowly and rack up API bills, and the Confident AI cloud jumps 10x from $200 to $2,000/mo. Here are five alternatives matched to why teams leave.
5 Galileo Alternatives With Real Self-Host and Public Pricing (2026)
Galileo is the best-funded eval platform in the space, but everything past the $100 Pro tier is contact-sales and self-host is Enterprise-only. Here are the alternatives, matched to why teams actually leave the sales motion.
4 Laminar Alternatives With Pricing You Can Forecast (2026)
Laminar is the most self-hostable agent-tracing tool in the category, but its Signals billing - metered by tokens spent reading your traces - is the hardest to forecast anywhere. Here are the alternatives that also self-host in full.
4 Maxim Alternatives That Skip the Double Billing in 2026
Maxim's agent simulation is a genuine differentiator, but it charges per seat AND caps logs, so a real team pays on both meters at once - and self-host is Enterprise-only with no open-source version. Here are four cheaper agent-eval alternatives matched to why teams leave.
3 OpenRouter Alternatives for Teams That Outgrew the Hosted Router (2026)
OpenRouter is a great hosted gateway for breadth - one key, hundreds of models. But it is closed, you cannot self-host it, and its dashboard is usage stats, not real observability. Here are the alternatives, matched to why teams actually leave - a self-hostable gateway, real tracing, and one open-source proxy to approach with caution.
5 Opik Alternatives Worth Switching To in 2026
Opik is the cheapest managed cloud in the category at $19/mo and the most permissive open-source license - Apache-2.0 with the full feature set self-hosted. But per-seat pricing scales poorly, and it is not OTel-native. Here are five alternatives, matched to why teams actually leave.
4 Portkey Alternatives When You Actually Wanted Observability (2026)
Portkey's open-source gateway self-hosts free, but the logs, traces and analytics most teams adopt an observability tool for live on the paid tier. Here are the alternatives, matched to whether you want a gateway or real logging.
4 Promptfoo Alternatives for a Vendor-Neutral Eval Stack in 2026
Promptfoo is the de-facto open-source eval and red-teaming CLI, MIT-licensed with the most GitHub stars of the major eval tools - but OpenAI acquired it in March 2026. If you want a vendor-neutral eval framework, here are the alternatives matched to why teams look.
4 Braintrust Alternatives That Bill Predictably (2026)
Braintrust meters processed data by the GB - every byte of inputs, outputs and metadata - with no spend cap and a $0 to $249 cliff. Here are four alternatives that price without the surprise.
4 Helicone Alternatives to Migrate To Before It Freezes (2026)
Helicone is in maintenance mode after Mintlify acquired it in March 2026 - security fixes only, no roadmap, and the vendor is helping customers leave. Here are four alternatives, matched to why you were on Helicone in the first place.
4 Langfuse Alternatives With Less Ops Overhead (2026)
Langfuse is the open-source default, but self-hosting it now means running four services - Postgres, ClickHouse, Redis and S3 - and it's a ClickHouse subsidiary as of January 2026. Here are four alternatives, matched to why people actually leave.
5 LangSmith Alternatives That Cost a Fraction at Scale (2026)
LangSmith is the most turnkey observability tool for LangChain apps - and roughly 25x more expensive than Langfuse at 1M traces, fully closed source, and locked to one framework. Here are five alternatives, matched to why people actually leave.
