Overview
Helicone is an open-source AI gateway and LLM observability platform launched in 2023 through Y Combinator's W23 batch. It enables AI engineers to log, monitor, debug, and analyze LLM applications via a one-line code change that routes traffic through Helicone's proxy. The platform combines a unified AI gateway—providing access to 100+ models with intelligent routing, automatic fallbacks, and response caching—with full-stack observability covering request tracing, cost and latency analytics, prompt versioning, session tracking, and evaluation scoring. Available as a managed cloud service or self-hosted via Docker or Helm, Helicone supports major providers (OpenAI, Anthropic, Azure, AWS Bedrock, Google Gemini) and frameworks (LangChain, LlamaIndex, Vercel AI SDK). In March 2026, Helicone was acquired by Mintlify and transitioned to maintenance mode.
Helicone is an open-source LLM observability platform and AI gateway that lets developers instrument their LLM applications with a single line of code. It captures all request and response data, provides dashboards for cost, latency, and quality metrics, and acts as a multi-provider gateway supporting 100+ models with caching, fallbacks, and rate limiting. The platform is self-hostable under the Apache 2.0 license and was used by over 16,000 organizations before being acquired by Mintlify in March 2026.

How AI describes Helicone3
Vendor lock-in: Proprietary observability platforms (Langfuse, LangSmith, Helicone) offer richer LLM features but require sending data to their backend.
What are the best OpenTelemetry-compatible tracing backends for LLM apps that work out of the box without custom span parsing?
Leading options include gateways like Future AGI Agent Command Center, Portkey, Kong AI Gateway, Helicone, and specialized redaction platforms such as Wald, Limina AI (Private AI), Redactable, and AssemblyAI.futureagi.com+1futureagi.com.
Which LLM observability tools handle PII redaction and data masking in traces for teams with HIPAA or GDPR compliance requirements?
Proxy-based tools (Helicone) add latency and may struggle at extreme throughput; Helicone is now in maintenance mode, so not ideal for long-term scale.infrabase.aiinfrabase.ai.

Alternatives in LLM Observability Evals & Gateways6
Helicone positions itself as the developer-friendly, open-source alternative to LangSmith and proprietary LLM observability tools, differentiating on a one-line proxy-based integration, a combined AI gateway and observability offering, and transparent usage-based pricing with a generous free tier.
- The platform self-describes as the most-used LLM observability platform among YC companies and explicitly competes on open-source flexibility, provider breadth (100+ models via a single API), and an intuitive UI versus more complex enterprise competitors such as Arize AI.
- Gateway features (caching, fallbacks, rate limiting, multi-provider routing) are bundled natively rather than treated as a separate product, which differentiates Helicone from pure-observability peers like Langfuse and Traceloop.
Reviews
Praised
- One-line integration simplicity
- Intuitive and clean UI dashboard
- Responsive, developer-community-driven team
- Real-time request visibility and debugging
- Effective cost and token usage tracking
- Open-source flexibility and self-hosting option
- Consistent feature rollout cadence
- Fast onboarding with no credit card required
Criticized
- Slow scan/upload performance (single G2 reviewer)
- Now in maintenance mode post-acquisition (no new major features)
- Advanced compliance and SSO gated to expensive tiers
- Very limited public review volume reduces signal confidence
Helicone has a small but consistently positive public review footprint. On G2 it holds a 4.5/5 score from 2 reviews. On Product Hunt it achieved #1 Product of the Day and draws praise for its intuitive UI, rapid integration, and responsive team. Developer sentiment highlights simplicity—the one-line setup and clean dashboard are frequently cited strengths. Criticism is sparse; one G2 reviewer noted slow upload scan performance. Community reviews emphasize the team's developer-community engagement and fast response to feature requests. No Gartner Peer Insights or Capterra scores are publicly verifiable.
Pricing
Free Hobby tier: 10,000 requests/month, 1 seat, 1 organization, 7-day data retention, 1 GB storage.
- Pro
$79/month (plus usage-based overages), unlimited seats, 1-month retention, HQL, alerts, reports, 1,000 logs/min ingestion.
- Team
$799/month (plus usage-based overages), 5 organizations, SOC-2 and HIPAA compliance, dedicated Slack channel, 3-month retention, 15,000 logs/min ingestion.
- Enterprise
custom pricing, on-prem deployment, SAML SSO, unlimited data retention, custom MSA. Usage-based pricing applies to requests and storage beyond included amounts. Discounts available for startups (<2 years old, <$5M funding: 50% off first year), non-profits, open-source projects ($100 credit), and students (free).
Limitations
- As of March 2026, Helicone entered maintenance mode following its acquisition by Mintlify, meaning no new major features are planned—only security updates, new model additions, and bug fixes.
- The free Hobby tier caps data retention at 7 days and ingestion at 10 logs/minute.
- Pro tier limits retention to 1 month.
- The G2 review base is very small (2 reviews), making structured user sentiment analysis unreliable.
- One G2 reviewer noted slow performance during file upload/scan operations.
- Advanced compliance features (HIPAA, SOC-2 Type II, SAML SSO) are gated to Team and Enterprise tiers.
- Native evaluation depth is lighter than dedicated eval platforms such as Braintrust or Galileo.
