Helicone is shutting down.
Migrate to LLMeter in 30 seconds.
Helicone was acquired by Mintlify in March 2026. Active development has stopped. 16,000+ teams need a new home for LLM cost monitoring. LLMeter is the open-source alternative — no proxy, no SDK, no code changes.

Why migrate now?
16,000+ organizations relied on Helicone in production. Here's what the acquisition means for you.
No new features
Mintlify confirmed: only security patches and bug fixes going forward. No new integrations, no new analytics, no roadmap. The product is frozen.
Proxy risk
Helicone proxies all your LLM traffic. A maintenance-mode proxy is a single point of failure you can't afford — one outage and all your LLM calls fail.
Zero-downtime switch
LLMeter uses read-only API keys — no proxy dependency. Switch monitoring tools without touching a single line of your application code.
Migrate in 3 steps
No SDK installation. No code deployment. No downtime. Just paste a key and go.
Sign up for LLMeter
Create a free account at llmeter.org. No credit card required. The Free plan supports 1 provider forever.
Create account arrow_forwardPaste your read-only API key
Go to your provider's dashboard (OpenAI, Anthropic, etc.), generate a read-only API key, and paste it into LLMeter. That's it — no code changes.
Remove the Helicone proxy
Revert your base URL and headers back to the provider defaults. No more proxy dependency, no more single point of failure.
Helicone vs LLMeter
A direct comparison on what matters most for LLM cost monitoring.
| Feature | Helicone | LLMeter |
|---|---|---|
| Setup method | Proxy (change base URL) | Read-only API key (no code changes) |
| Time to first dashboard | ~5 min (SDK/proxy config) | 30 seconds |
| Code changes required | Yes (base URL, headers) | None |
| Open source | Yes | Yes |
| Active development | close Maintenance mode only | check Active |
| Multi-provider support | OpenAI, Anthropic, more | OpenAI, Anthropic, Google AI, Mistral, DeepSeek, OpenRouter |
| Budget alerts | Basic | Advanced (anomaly detection, daily thresholds, Slack) |
| Free tier | 10K requests/mo | Free forever (1 provider) |
| Sees your prompts? | Yes (proxies all traffic) | check Never |
| Team features | Yes | Yes (Team $49/mo, Enterprise) |
No proxy. No risk.
Helicone routes all your LLM traffic through its servers. LLMeter takes a fundamentally safer approach.
close Helicone — proxy-based
- close All LLM traffic routed through Helicone servers
- close Proxy outage = your LLM calls fail
- close Requires base URL changes and header injection
- close Third party sees all prompts and completions
- close Added latency on every LLM call
check LLMeter — API key-based
- check Reads usage data directly from provider APIs
- check Zero impact on LLM call latency or reliability
- check No code changes — paste a read-only key and go
- check Never sees your prompts or completions
- check Your traffic path stays unchanged
Migration FAQ
Why is Helicone shutting down active development? expand_more
Helicone was acquired by Mintlify in March 2026. The Mintlify team announced that active feature development has ended — only security patches, bug fixes, and new model support will continue. The 16,000+ organizations using Helicone in production are encouraged to plan their migration.
Does LLMeter require me to change my API base URL? expand_more
No. Unlike Helicone's proxy approach, LLMeter uses read-only API keys to fetch your usage data directly from the provider. Your application code stays untouched — no base URL changes, no headers, no SDK.
Can LLMeter see my prompts or completions? expand_more
No. LLMeter only accesses usage and billing data through read-only API keys. We never see your prompts, completions, or any content flowing through your LLM calls. This is a fundamental architectural difference from proxy-based tools like Helicone.
How long does migration take? expand_more
Setting up LLMeter takes about 30 seconds — just paste a read-only API key. Removing the Helicone proxy from your codebase depends on how many services use it, but for most teams it's a one-line revert per service. You can run both in parallel during transition.
What if I need features Helicone had that LLMeter doesn't? expand_more
LLMeter focuses on cost monitoring, budget alerts, and optimization — the core features most teams use Helicone for. If you relied on Helicone's prompt logging or evaluation features, those are outside LLMeter's scope. For pure cost visibility, LLMeter is a drop-in replacement.
Is LLMeter free? expand_more
Yes — the Free plan supports 1 provider with 30-day retention, forever. The Pro plan ($19/mo) adds unlimited providers, alerts, anomaly detection, and 1-year retention. Team plans start at $49/mo for collaborative monitoring.
Don't wait for the proxy to go dark.
