The main question
Need a Simple Solution for Slack or a Big Behemoth Discovery Tool?
We don't yet have connectors for Teams, Google, or others. If you just need Slack support, ViewExport offers the most robust features per dollar for enterprise search and discovery.
We're purpose built for Slack
Since we aren’t trying to be the custodians of all of your data everywhere in your organization, we’ve created an easy to use platform just for Slack. Not for ‘everything’.
It's easy to sign up and go
As a subsidiary of Reveal, Onna doesn’t display pricing publicly and requires you to contact a salesperson. That’s fine. Or you can sign up with ViewExport in minutes.
Simpler and priced affordably
Onna’s median price point, based on Vendr data in 2025, was $180,507. ViewExport’s typical Enterprise pricing is 5-15k/yr, a significant cost benefit.
Security
Security Focused Platform
Both Onna and ViewExport have full security, audit trail, and logging features. You’ll have a detailed log of clicks and updates to just about everything, no matter which one you choose.
Ensures system actions are logged and traceable
Reliable paper trail when investigating user activity
Use Case Focus
Same goal. Different scope.
Both tools live in the same world. The question is how much of that world you actually need to cover.
eDiscovery & Info Governance
Both Onna and ViewExport solve for an eDiscovery and information governance use case. ViewExport solves it only for Slack, whereas Onna covers many different data sources.
Private Equity Owned or Closely Held?
When you do business with ViewExport, you’re working directly with the partners who own and operate the business. Your quality of customer support is stellar. There’s nothing wrong with buying from a PE-backed enterprise; it’s just different.
Product Overview
The Slack export viewer built for review and audit.
Legal and IT teams hit walls fast: no easy way to filter by date range, no way to search across DMs or private channels without triggering "joined channel" alerts, and no way to make sense of raw JSON files without hours of manual effort.
Native Slack tools don't support scoped date searches well
Filtering Slack messages by date range isn’t easy natively—making legal holds, audit prep, and early case assessment slow and error-prone.
Accessing private channels in Slack notifies users — not ideal for audits
Joining private channels triggers alerts and raises red flags in sensitive HR, compliance, or internal investigations.
Slack exports come in raw JSON, unreadable without technical help
Parsing Slack’s JSON exports eats up billable hours and internal IT time before legal review even begins.
Security
Enterprise-Grade Security, Built for Legal Workflows
ViewExport is designed with strict security, access controls, and audit trails to meet your legal, IT, and compliance standards.
Immutability
Audit logs are locked by default and cannot be altered or removed by any user — including administrators. This preserves a tamper-proof record of activity for legal defensibility and regulatory assurance.
Retention
All audit logs are automatically retained for a minimum of 12 months, in line with common legal and regulatory requirements. Optional custom retention settings allow longer storage where needed.
Access Control
Only designated administrators with the correct roles and permissions can view or query audit logs. This reduces exposure risk and aligns with internal access control policies and compliance frameworks.
Encryption
Audit logs are encrypted at rest using industry-standard protocols. This ensures that sensitive access data remains secure, even in the unlikely event of a system compromise.
Sensitive Data Protection
Passwords, access tokens, and API keys are automatically filtered and excluded from all logs, preventing accidental logging of high-risk secrets, and protecting both internal systems and user privacy.
Compliance Support
Audit logging helps you align with your GDPR, SOC 2, ISO 27001, and HIPAA compliance requirements. Combined with access control and retention policies, we support your audit-readiness out of the box.

We're compatible with all Slack plans: Free, Pro, Business, and Enterprise. Just export any Slack JSON archive!
Yes! Find pricing for the downloadable, local-hosted edition of ViewExport on our pricing page. Great for if you have security concerns about employee data leaving your private cloud, or if your contractual obligations prevent sensitive IP from touching third-party servers. With the local edition, we'll never see or have access to your Slack data files.
You can upload anything that is included with the .ZIP file that contains your .JSON exports from Slack. If those files contain private channel and direct message data, they'll be searchable in ViewExport as well. However, we can't help you get data from Slack that was not contained in your export.
There's no implementation required: ViewExport is as easy as setting up an account, and uploading a .ZIP file. That said, we're happy to walk you through configuration and best practices.
We take security seriously and serve organizations around the world who are entrusted with strict data governance procedures, including for their Slack data. Here's our full security overview.

No, ViewExport is an independent service not affiliated with Slack Technologies Inc. We provide tools to view and search Slack export files but are not connected to, funded by, or endorsed by Slack.
ViewExport is a modern, cloud and desktop platform for searching and governing corporate Slack messages to maintain compliance. Think of us as a single-purpose tool — an alternative to Onna, Mimecast Aware, Hanzo, Smarsh, and Pagefreezer. Technical teams can also compare us to Slackdump or Backupery, or read why teams outgrow Slack's native export for legal review. Message Crawler customers will also enjoy switching to ViewExport so that they can filter and search their Slack archives before uploading them to Relativity, saving a reported $10-50k per year on RelOne data and hosting costs, according to some of our customers. You can read more here about the top Slack eDiscovery tools available.
The free trial is 7 days with a nominal data usage limit to prevent abuse. We want you to know that we're able to handle your needs, and we've noticed that most organizations can determine this in 24-48 hours. Need help with your trial?
