Helicone = observability proxy bolted on top of your direct provider keys. Portkey = enterprise routing + guardrails. jusCode = coding-agent-specific router with per-step model selection. Pick the one whose primary axis matches your highest-pain problem. key_takeaways: - OpenRouter is a price marketplace; Helicone is observability on your own keys. - Portkey is enterprise routing and guardrails; jusCode is coding-agent per-step routing. - Pick the gateway whose primary axis matches your highest-pain problem. --- # LLM gateway comparison 2026 "LLM gateway" gets used to mean four different products. Picking the wrong shape is the most common mistake we see: a team installs an observability proxy when they actually needed a router, or installs a router when they actually needed cost telemetry on their existing provider keys. The four shapes: | Shape | Example | Optimizes for | What you give up | |---|---|---|---| | **Marketplace** | OpenRouter | Lowest-price access to many models | No per-step routing intelligence; pay-per-use markup | | **Observability proxy** | Helicone | Telemetry, logs, retries on YOUR keys | No price optimization; you still pay the underlying provider directly | | **Enterprise router** | Portkey | Governance, fallbacks, PII redaction | Heavier setup; priced for orgs not individuals | | **Coding-agent router** | jusCode | Per-step model selection for coding workloads | Not optimized for chat, image, embeddings | ::figure{template=compare caption="Four shapes of LLM gateway" items="OpenRouter :: marketplace, cheap access | Helicone :: observability on your keys | Portkey :: enterprise routing + guardrails | jusCode :: per-step coding router"} ## OpenRouter **What it is**: a marketplace. You send a request specifying a model id (`anthropic/claude-sonnet-4`, `deepseek/deepseek-chat`, etc.); OpenRouter forwards to the cheapest-currently-available provider hosting that model and charges you their price plus a small markup. **Best for**: getting access to many models behind a single key, especially open-weight models hosted by multiple inference providers (Together, Fireworks, DeepInfra, etc.) where price varies day to day. **Where it's weak for coding agents**: you still pick the model. OpenRouter doesn't watch your conversation and route an "is this file a JSON config?" question to a small model. If you pin Claude Sonnet in your harness, every step uses Claude Sonnet. ## Helicone **What it is**: a proxy you point your existing OpenAI/Anthropic SDK at by swapping the base URL. Your keys stay yours; Helicone logs every request, computes per-user cost, exposes a dashboard. Free tier covers a generous quota. **Best for**: teams that already standardized on a direct provider and want telemetry without changing their billing model. **Where it's weak**: no price optimization layer. If your bill is $X today with the direct provider, your bill is still $X with Helicone. You just see it itemized. Adding routing requires migrating to a different product class. ## Portkey **What it is**: an enterprise-shaped router with guardrails (PII redaction, prompt firewalls), multi-provider fallback chains, cost budgets per virtual key, and an audit-log surface. **Best for**: orgs with a procurement process, compliance requirements, or multi-team budget allocation. The configuration surface is rich because that's what enterprises need. **Where it's heavier than you want**: for an individual developer or a small team, Portkey's setup-to-value time is longer than the alternatives. The features pay back at scale, not at one-developer scale. ## jusCode **What it is**: a router specifically for coding-agent traffic. Same OpenAI-compatible API surface, but the model selection inside the gateway is informed by what a coding loop looks like: short "read this file" turns get cheap models, "rewrite this 400-line function" gets a stronger one, "design this system" gets reasoning-capable. **Best for**: people running Claude Code, Cursor, Cline, OpenCode, Aider, or any other coding agent and watching their monthly bill grow with usage. **Where it's weak**: not optimized for image generation, embeddings, fine-tuning, or chat-style consumer products. The per-step routing logic encodes "what does a coding turn look like." Applied to chatbot traffic, it just looks like a regular cheap-by-default proxy. ## Decision matrix Pick by your highest-pain problem: | Your pain | Pick | |---|---| | "I want access to 100+ models behind one key, even niche open-weight ones" | OpenRouter | | "My provider bill is fine, but I have no visibility into who's burning the most" | Helicone | | "Compliance + budgets + multi-team governance is the bottleneck" | Portkey | | "My coding-agent bill is growing faster than my team" | jusCode | | "I want all of the above" | Compose two: Helicone in front of jusCode, for example. They're not exclusive. | ## What about combining? You can. Helicone is content-neutral: it'll happily proxy any OpenAI-compatible endpoint, including jusCode's. Stack order: ``` your harness → Helicone (telemetry) → jusCode (per-step routing) → underlying provider ``` Your Helicone dashboard shows the request to jusCode; jusCode's dashboard shows the routed underlying model. Two layers of visibility, one bill at the bottom. What you can't usefully stack: two price-optimization layers (OpenRouter behind jusCode, or vice versa). One of them ends up just being a passthrough that adds latency without changing the routed model. ## Honest weaknesses of each (we've used all four) - **OpenRouter**: quality varies day to day as it shifts between sub-providers. Fine for batch, occasionally surprising for interactive coding. - **Helicone**: sampling at scale needs paid plan; free tier hits limits quickly under heavy agent traffic. - **Portkey**: config-as-data is powerful but takes a day to internalize for a new user. Not a "5-minute install." - **jusCode**: narrower scope; if your workload is 50% coding agents and 50% something else, the savings only land on the coding half. ## When the right answer is "none, go direct" Three cases: 1. You're under $20/month of inference: gateway cost (free or otherwise) is solving a problem you don't have. 2. You're locked to one model intentionally (a research project measuring one specific model's behavior). 3. Your tooling doesn't support custom base URLs (rare in 2026; even Cursor and Copilot have it now). ## Further reading - [Cheapest LLM API for coding 2026](/blog/cheapest-llm-api-for-coding-2026): narrower per-model price comparison - [OpenRouter alternatives 2026](/blog/openrouter-alternatives-2026): what to pick if OpenRouter isn't fitting - [Together vs Fireworks vs jusCode](/blog/together-vs-fireworks-vs-juscode): inference provider comparison (different layer) ## FAQ ### What is the difference between OpenRouter and jusCode? OpenRouter forwards a model you pick to the cheapest host and adds markup. jusCode watches the coding task and picks a different model per step, so you do not pin one expensive model for every call. ### Is Helicone a router? No. Helicone is an observability proxy on your existing provider keys. Your bill is unchanged; you just see it itemized. Routing needs a different product class. ### When should I not use any gateway? If you use one model, one provider, one key, and have no cost or failover pain, going direct is simpler.
