Sentry Seer is priced per seat, not per fix. That single fact determines everything about how the bill behaves, so it is worth being precise about it.
The current price
$40 per active contributor per month, on top of whatever Sentry plan you already pay for. Sentry's docs define an active contributor as any user who makes two or more pull requests to a Seer-enabled repository, and state that all members of your repositories are counted except GitHub bots marked [bot].
Read that definition twice. The unit is contributor to the repository, not user of the agent. A backend engineer who has never opened Seer, but who merged two pull requests last month, is billable.
What changed in January 2026
The previous model was $20 per month per subscription plus $25 worth of Seer event credits, drawn down by Issue Scans and Issue Fixes, with overage against a pay-as-you-go budget. Sentry stopped offering that as an add-on in January 2026 in favour of the flat per-contributor price.
The trade is legible: usage-based billing became forecastable billing, and in exchange the floor rose for teams that use the agent occasionally.
What it costs as you grow
| Active contributors | Seer per month | Seer per year |
|---|---|---|
| 3 | $120 | $1,440 |
| 8 | $320 | $3,840 |
| 20 | $800 | $9,600 |
| 50 | $2,000 | $24,000 |
Those are Seer alone, before the underlying Sentry plan. The arithmetic is just the published unit price multiplied by headcount; you can check every row against Sentry's pricing docs.
The column that is not in the table is the one that matters: the cost of a month in which the agent fixed nothing is identical.
Whether that is bad depends on you
Seat pricing is not a scandal. It is forecastable, it is easy to approve, and for a team that runs the agent constantly it is probably cheaper than metering. If you have three contributors and you want an AI debugger inside a platform you already run, $120 a month is a straightforward purchase and you should make it.
It gets uncomfortable at the other end. A fifty-person engineering organisation pays $24,000 a year for Seer whether it opens four pull requests or four hundred, and forty of those fifty people may never look at it.
The other shape a bill can have
Parsemend charges a flat framework fee and does not resell you inference. You bring an Anthropic, OpenAI, Gemini or Ollama credential; your provider bills you directly at their published rate; and a month with no fix runs costs you no tokens at all. The headcount of your engineering team does not enter the calculation.
We are not going to print a head-to-head total here, because Parsemend's own tier prices are not final, and comparing a real number to a placeholder would be worse than saying nothing. What we can compare is the shape: Seer's bill is a function of how many people commit to your repository, and ours is a function of how much work the agent actually did. See Parsemend vs Sentry Seer.
