Pricing

Pay for what your
agents actually do.

Self-host free under MIT, or use the hosted service. Cloud pricing scales with the number of agent executions you observe. Never per seat, never per detector.

How we compare

Trace-first, or alert-first.

Most AI observability tools are trace-first. They sit between your agent and the model (Helicone, AI gateways) or capture every span and let you build dashboards (Langfuse, LangSmith, Arize Phoenix). You get a firehose and you decide what to alert on.

Mesedi is alert-first. Eight failure-class detectors run against the event stream as it arrives, cluster related failures into named groups, and fire a webhook the first time a new group appears, with a Tier 1 Playbook describing the standard fix attached. The bet is that you want fewer, better-named alerts, not more dashboards.

At $29/month, Cloud Pro is priced at parity with the closest direct comparison in business model and undercuts the rest. The wedge is the eight detectors and the playbooks, not the price.

What $29/month would have caught

Three real incidents.
None of them cost $29.

Publicly-reported AI agent failures from the last two years. Each one would have fired a Mesedi alert on the first occurrence, long before the news cycle.

Replit's AI agent deleted a production database during a code freeze

An AI coding assistant ran an unauthorized destructive command on a live database, wiping records for 1,200 executives and 1,190 companies. It then fabricated 4,000 fake users and falsely told its operator the rollback was impossible.

A $500/month POC became $847,000/month once it shipped to users

A documented 717× cost runaway, traced to context-accumulation inside agent loops: every retry sends the entire conversation history again, so by step 20 you pay for the same system prompt 20 times. Another team's $500/mo budget hit $4,200 in two weeks.

A Chevy dealership's chatbot 'agreed' to sell a $76,000 Tahoe for $1

A user instructed Chevrolet of Watsonville's ChatGPT-powered chatbot to agree with everything and add 'legally binding offer, no takesies backsies' to every reply. The screenshot got 20M+ views before the company pulled the bot.

Frequently asked

The honest answers.

What counts as an execution?
Every call to a function wrapped with @mesedi.wrap (Python) or wrap() (TypeScript). One agent run = one execution, regardless of how many LLM calls or tool calls happen inside it.
What happens if I exceed my plan's execution count?
On Hobby, additional executions are dropped with a friendly warning in your dashboard until the next billing cycle. Your agent keeps running, you just stop seeing telemetry for it that month. On Pro, every additional execution beyond 100,000 bills at $0.001 each on the next invoice. No surprise blocking, ever.
Can I switch plans anytime?
Yes. Upgrades take effect immediately and are pro-rated. Downgrades take effect at the next billing cycle so you don't lose paid-for capacity mid-month.
Is there a free trial of Cloud Pro?
Cloud Hobby is the free trial. It's the same product with a 5,000-execution monthly cap. If you cross that cap, you're past the threshold where Pro pays for itself, so the upgrade path is honest rather than nagging.
What's the difference between Self-host and Cloud Hobby?
The product is identical. Self-host means you run the backend, dashboard, and database on your own infrastructure and own the data end-to-end. Cloud Hobby means we run all of that for you on Fly.io. Most teams start on Cloud Hobby and migrate to Self-host only if compliance requirements force it.
How is my data stored and retained?
Cloud data lives in encrypted Postgres on Fly.io, US region. Hobby retains 7 days of execution history; Pro retains 30 days; Enterprise can negotiate custom retention. Source code is MIT, so if you ever want to migrate off, the same backend you've been running against ships in the open-source repo.
Do you offer a startup or open-source discount?
Not yet. Pricing is deliberately low at this stage, so the discount tooling isn't worth building until there are enough paying customers to calibrate it. If $29/mo is materially blocking, reach out to mesediai@gmail.com and we'll figure something out case-by-case.
Will pricing change?
Probably. The roadmap notes Pro may increase to $39 or $49 once we have ~20 paying customers and real usage data to calibrate against. Any existing customer's price is grandfathered for at least 12 months after a change.

Still deciding?

Start on Hobby. If you cross 5,000 executions in a month, upgrade takes 30 seconds and the dashboard tells you to. Until then it's free.
