Pricing
PandaProbe Cloud: Offers a free Hobby plan (100 base traces/mo, 1 seat). Pro at $29/month (5k traces, 2 seats). Startup at $299/month (50k traces, 10 seats). Enterprise with custom pricing (unlimited seats, hybrid hosting, SSO, SLA).
Mellum by JetBrains: Free and open-source under Apache 2.0. You only pay for the infrastructure you use (e.g., cloud GPU instances, local hardware). No per-token or subscription fees.
Pros and Cons
PandaProbe Cloud
Pros:
- Zero infrastructure management β fully managed service.
- Built-in eval LLM and embedding models (no external API keys).
- Auto-scaling and continuous monitoring out of the box.
- SSO, RBAC, and SLA support for enterprise teams.
- Quick setup (minutes) and easy to get started.
Cons:
- Proprietary service β vendor lock-in for monitoring.
- Costs can scale with usage (pay-as-you-go over base limits).
- Limited to agent monitoring/tracing; not a general-purpose LLM.
Mellum by JetBrains
Pros:
- Free and open-source (Apache 2.0) β full control and privacy.
- Ultra-low latency and high throughput (MoE architecture).
- Can be deployed locally or on cloud β flexible infrastructure.
- Strong coding and language performance for its size.
- Active community and JetBrains backing.
Cons:
- Requires self-managed infrastructure (deployment, scaling, monitoring).
- No built-in tracing, evals, or monitoring tools.
- Community support only; no formal SLA.
- May need additional tooling for production agent workflows.
Verdict
Choose PandaProbe Cloud if you want a fully managed solution for tracing, evaluating, and monitoring AI agents without worrying about infrastructure. Choose Mellum by JetBrains if you need a fast, open-source LLM for low-latency inference and prefer to control your own deployment and tooling. They can complement each other β use Mellum as the model and PandaProbe to monitor it.
