Questions
Is Parsemend a replacement for Sentry?
For errors, logs, traces, cron and uptime monitoring, yes, and coming from Sentry only the DSN changes. It has no session replay, profiling or performance dashboards.
Sentry has an MCP server too. What is different?
Sentry pairs its server with Seer, an agent you pay for per contributor and give repository access to. Parsemend has no agent to sell, needs no repository access, and costs €9 a month flat.
Can I run both at once?
Yes. Initialise the SDK with two DSNs, or fan events out with a relay, and compare.
Comparing the AI agents specifically? Parsemend vs Sentry Seer. Moving over? Migrating from Sentry.
