ViewExport vs Slackdump
Overall: Slackdump is an open-source CLI that pulls a Slack workspace into raw JSON. ViewExport is what legal, IT, and HR teams use to actually search, redact, and export that data — without anyone having to run a Go binary.
ViewExport vs Slackdump Overview
Slackdump gets you the data. ViewExport makes it usable.
Slackdump is genuinely good at one thing: turning a Slack workspace into JSON files you control. Everything that happens after that — searching, filtering, redacting, producing for outside counsel — is on you.
| Feature | ViewExport | Slackdump |
|---|---|---|
| Primary Focus | Search, redact, and export Slack data for legal, IT, and HR teams | Open-source CLI that downloads a Slack workspace into JSON files |
| Who It's For | Legal, compliance, IT admins, HR investigators — non-technical users | Engineers, security researchers, technical users comfortable with the terminal |
| Pricing | Cloud plans start at $499/mo; enterprise from $6k/yr; desktop annual license available | ✅ Free and open source (MIT license) |
| Setup | ✅ Sign up and upload a Slack export, or install the desktop app | Install Go binary, configure auth tokens, run from terminal |
| Search & Review UI | Full-text search, date filters, channel/user filters, redaction, exports | ❌ None — output is raw JSON. The Slackdump README recommends third-party viewers |
| Audit Trail | Immutable audit logs of every search, view, and export | ❌ Not provided |
| Defensible Exports | PDF and CSV bundles with metadata for legal review | JSON only — you build your own review workflow on top |
| Data Locality | Cloud or desktop edition (Mac and Windows). Desktop keeps everything on your machine. | Always local — files land on the machine that runs the CLI |
The main question
Are your reviewers engineers, or are they not?
That single question tells you which tool you need. Slackdump assumes its user can read JSON and write a script. ViewExport assumes they cannot — and shouldn't have to.
Built for non-technical reviewers
Attorneys, compliance officers, HR partners, and IT admins shouldn’t be running CLI tools or parsing JSON to answer a legal hold or a DSAR. ViewExport gives them a real interface for the actual task.
Search and redact, not just download
Filter by date range, user, channel, or keyword. Redact PII before handing data to outside counsel. Produce defensible PDF or CSV bundles with attached metadata. Slackdump stops at the JSON file.
Audit logging out of the box
Every search, view, and export in ViewExport is logged immutably. For HR investigations or regulator inquiries, that chain of custody is the difference between “we looked into it” and “here is the record of every action our reviewers took.”
When to pick Slackdump
Honest take: Slackdump is the right call for these cases
If you're a technical user with a specific job to do and no review workflow to support, Slackdump is genuinely a great option. We're not trying to talk you out of it.
You're an engineer doing a one-time pull
You need the data on disk, you’ll write a Python script to extract what you need, and you’ll never look at this workspace again. Slackdump is faster than spinning up a SaaS account.
You're piping into your own tooling
You’ve already built ingest into Elasticsearch, Relativity, or a home-grown review platform. You don’t need a UI — you need clean JSON in a known format. Slackdump delivers that.
Budget is genuinely zero
Slackdump is free. If you have a strict no-spend constraint and you also have the engineering time to support reviewers manually, it’s a defensible choice.
When to pick ViewExport
If a non-engineer ever has to use the output, switch
The minute a paralegal, compliance officer, or HR partner has to look at the data, the math changes. Their hourly rate is higher than our license — and they cannot review raw JSON.
Same data, but reviewable
ViewExport ingests the same Slack export format Slackdump produces. If you already have JSON exports sitting on disk, you can upload them today and have searchable, filterable, redactable data in minutes.
Desktop edition if data must stay local
Worried about uploading sensitive Slack data to a SaaS? ViewExport has a Mac and Windows desktop edition. Annual license, runs forever, your data never touches our servers. Same security posture as Slackdump, with a real review UI on top.
No Go binaries in your audit trail
Security teams don’t love handing CLI tools to non-engineers, and they really don’t love them in regulated environments. ViewExport is a vetted SaaS or signed desktop application — easier to defend in an audit.
The combined workflow
A lot of teams use both
There's no rule that says you have to pick one. Plenty of customers use Slackdump to pull data — especially from workspaces where they don't have admin access to run an official export — and then load the output into ViewExport for review.
Slackdump for acquisition
Use the CLI when you need flexibility in how the data comes out, when you’re grabbing a private channel you have user-level access to, or when official export isn’t available.
ViewExport for review
Hand the resulting JSON to ViewExport. Your reviewers get a real interface, your audit trail is intact, and your defensible production is a few clicks away.
Best of both worlds
Free, flexible data extraction plus a paid, supported review layer. That’s a stack most legal-ops teams can live with.

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.

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.
