Will Rovo Replace ScriptRunner? My Take After 3 Months

[#1]

Short answer: No, but it will replace 40 percent of simple scripts. Here’s the breakdown.

What ScriptRunner still wins:

Complex workflows: If issue links to Epic and Epic label contains X, then copy 5 custom fields and trigger a webhook. Groovy is still faster to write and debug for pure logic.
Performance: Need to update 5,000 issues nightly. A scheduled ScriptRunner job finishes in 2 minutes. Rovo would time out.
Determinism: For audit logs and finance, you need the same output every time. Scripts do that. LLMs do not.
Where Rovo wins:

Text and reasoning: Summarize customer comments, draft release notes, classify sentiment, suggest components. You’d need ML libraries in ScriptRunner for this. Rovo does it in one prompt.
Speed to first version: Non-developers can ship a working agent in 1 hour. ScriptRunner needs Jira admin + Groovy skills.
Maintenance: Business rules change often. Updating a Rovo prompt is easier than redeploying a script for most teams.
The future is both:
Use ScriptRunner or Forge for bulk data and strict logic. Use Rovo Agents for the last mile of judgment and content. Example: Automation triggers when issue is created. ScriptRunner enriches 10 fields. Then it calls Rovo to draft the customer reply.

If your ScriptRunner library is 80 percent field copy and validators, expect Rovo to replace a lot of it. If it’s complex math and bulk updates, keep ScriptRunner.

at the same or lower cost?

I feel like Rovo isn't going to replace Scriptrunner, at least for the near future. You already mention the limitations of Rovo in your comparison and we don't know what Rovo will cost yet. 

Also when you say "ScriptRunner needs Jira admin + Groovy skills", I don't think that's totally true anymore. I am a Jira admin and I have 0 Groovy skills but I have no issues coding in Groovy using AI (Cursor/Copilot) to write what I need for Scriptrunner.
