PostHog Event Cleanup CLI & Bulk Manager
A CLI tool and web interface specifically for PostHog users to search, filter, and bulk-delete or archive events. Fills the immediate gap for self-hosted PostHog users who need data hygiene but cannot wait for native deletion support from the platform.
Why this matters
You administer a self-hosted PostHog instance and your analytics database is cluttered with test events, erroneous payloads, and stale data from old feature implementations. You have direct database access, but writing custom ClickHouse deletion queries is risky and error-prone without proper tooling. There is no admin UI for managing event lifecycle. When someone asks you to clean up survey responses or remove bad data, you are stuck either doing nothing or running potentially dangerous database operations without proper safety checks or audit trails.
- · Built for Self-hosted PostHog administrators and data teams who need to clean up erroneous events and manage data lifecycle without waiting for native platform support.
- · Most likely monetization: Freemium with paid tier for bulk operations, scheduling, and team dashboard access.

DevOps engineers and platform administrators managing self-hosted PostHog instances at companies with 50-500 employees
~5,000-10,000 self-hosted PostHog instances globally with active data management and cleanup needs
PostHog community engagement — GitHub issues, community chat, and documentation contributions
$29/month for CLI Pro with bulk operations, $99/month for team dashboard with scheduling and audit logs
100 free tier installs and 10 paid users within 60 days, primarily from PostHog community engagement and word of mouth
MVP Scope · 1–2 weeks
- Build ClickHouse query library for searching events by user ID, property, and time range with pagination
- Implement safe deletion function with mandatory dry-run mode and interactive confirmation prompts
- Create CLI interface with subcommands for search, delete, export, and audit log generation
- Add connection handling for both self-hosted ClickHouse access and cloud PostHog API access
- Write documentation and quick-start guide covering installation and common cleanup scenarios
- Add bulk deletion operations for removing all events matching a filter pattern with batch processing
- Implement scheduled cleanup job runner using cron-based scheduling for recurring maintenance tasks
- Build web dashboard for non-CLI users with search, preview, and delete workflow
- Add audit log export functionality in JSON and CSV formats for compliance documentation
- Launch free tier on public package registry and post in relevant community channels for feedback
Differentiation
Why This Might Fail
Self-rebuttal — the most important trust signal
- 1PostHog is actively developed with strong community engagement; native event deletion could be shipped within months given the clear user demand, instantly eliminating the tool's core value proposition for its only target platform.
- 2Self-hosted PostHog users are typically more technical and cost-sensitive, potentially unwilling to pay for a tool they could build themselves with ClickHouse knowledge and existing open-source utilities.
- 3Direct database operations on ClickHouse carry inherent risk of data corruption or query performance degradation on large datasets, and any incident could permanently damage the tool's reputation in the tight-knit self-hosting community.
Evidence Summary
How AI synthesized this insight — no verbatim quotes
The discussion centers on PostHog's lack of event deletion, with approximately 8 commenters expressing need and 7 or more support tickets referenced. One commenter proposed a soft-deletion workaround using additional marker events. The immediate pain is felt by administrators who cannot clean up bad data from their analytics instances. Self-hosted users with direct database access represent the most actionable initial segment, as programmatic deletion is technically feasible for them. However, the specificity to a single analytics platform limits the overall market opportunity and increases platform-risk exposure.
