Every plan watches your agents run; paid plans also evaluate whether each run achieved its goal, out of the box, nothing to configure. Free plan, no card required. Named limits. No metered billing. No surprise overages.
For wiring up your first agents.
For your first production agents.
For teams running agents in production.
For larger fleets and longer memory.
Most customers spend between $1,500 and $50,000 a month on LLM tokens. Agent Ping typically costs 1 to 3% of that. The maths is straightforward: every paid tier sits below the variance you already see month to month on your OpenAI or Anthropic invoice. The first cost spike Agent Ping catches, the kind of bug that turns a $4,000 bill into $12,000, pays for the next twelve to twenty-four months of subscription on its own.
| Starter | Team | Business | |
|---|---|---|---|
| Agent Ping | $99/mo | $199/mo | $399/mo |
| Typical events tracked | 1M | 5M | 12.5M |
| Implied agent runs | ~100K | ~500K | ~1.25M |
| Typical LLM spend | ~$3,000/mo | ~$15,000/mo | ~$37,500/mo |
| % of LLM bill | 3.3% | 1.3% | 1.1% |
Drop in your monthly LLM spend; we'll show you which tier fits and how much of your bill we'd account for.
Rough monthly OpenAI + Anthropic + Bedrock + Gemini total. If you're not sure, $15,000 is a typical mid-size team.
Most agents report 5-30 events per run. Lower if your agents are simple webhooks; higher if they're multi-step with tool calls.
Roughly: $0.01 for Haiku-only, $0.03 for a Sonnet-heavy mix, $0.08+ for Opus-heavy work.
These numbers assume an average of 10 events per run and a balanced model mix at around $0.03 per run. Your actual mileage depends on how chatty your agents are and which models they use. The point isn't the exact percentage; it's the order of magnitude. If your monthly LLM spend has a comma in it, Agent Ping pricing rounds to a rounding error.
If you don't know what your monthly LLM bill is right now, that is exactly the problem Agent Ping is built to solve. Once you can see cost per agent, per customer, and per feature, the conversation moves from "is this expensive" to "where do we cut without breaking things."
Agent monitoring and LLM observability tools charge on one of three axes: the people who look at the data, the volume of data your agents send, or a flat tier with named limits. Each is reasonable. Each gets expensive in a different place, so it is worth knowing which axis you will grow along before you pick.

From each vendor's public pricing page in October 2026; check theirs before deciding, as prices change. Units are not comparable one to one: a Langfuse unit, an AgentOps event and an Agent Ping event each count different things. Several of these tools are cheaper than Agent Ping to start, and LangSmith and Langfuse both have free tiers that suit a single developer well. The useful comparison is your projected bill at twelve months, at the seat count and run volume you expect then.
Retention is two honest numbers: how long you can open the full step-by-step trace of a run, and how long every run's outcome, evaluation result, cost, and trend survives. Most tools keep 14 to 30 days unless you pay per-trace for more; Agent Ping keeps your run history for a year on Team and Business, with 180 days of full detail on Business.
We charge for what your agents do, not how many people watch them. Invite your whole team on every plan, including Free, and use teams to separate staging from production or one client from another.
