A Codegeist winner with zero-knowledge encryption. A CRM built entirely on Forge. Three separately-funded AI companies shipping agents straight into Confluence. 2026 has been a genuinely strange, fast year for the Atlassian ecosystem, and most of it never shows up on the front page of the Marketplace because the front page ranks on install count, not on what’s actually new.
Quick answer: The most notable new Atlassian apps in 2026 include GitHub Copilot for Jira (assign a Jira issue to a coding agent), the new Lovable/Replit/Gamma partner agents inside Confluence, Sync-o (governed, auditable documentation sync), Riffle (VC-backed operational resilience), and several Codegeist 2025 winners like Frank. and Secure Notes for Jira.
This list ranks on two things: verified traction where it exists (install counts pulled directly from live Marketplace listings, not vendor claims) and genuine technical differentiation where the app is too new to have traction yet. Both criteria are labeled below, so you can weigh them yourself.
1. GitHub Copilot for Jira
Assign a Jira issue directly to a GitHub Copilot cloud agent. It reads the ticket, drafts the pull request, and streams progress back into the comment thread, so the loop from “here’s the bug” to “here’s the diff” never leaves Jira. This is the best-corroborated story on this list: GitHub’s own changelog confirms the GA date, independent coverage from DevOps.com backs it up, and it already has its own thread in Atlassian’s community forums.
Live numbers: 1,725 installs, version 12.3.0, GA’d June 25, 2026. No reviews yet, which is normal for something this recent.

2. Confluence’s new AI partner agents (Lovable, Replit, Gamma)
This isn’t a single app, and that’s exactly why it matters more than most single apps on this list. Atlassian shipped native Confluence integrations for three separately massive AI companies at once: Lovable turns a written spec into a working prototype, Replit turns a technical doc into a forkable starter app, and Gamma turns meeting notes into a presentation deck. Atlassian is a strategic investor in Lovable’s Series B, so this isn’t an arm’s-length partnership; Atlassian has money in the outcome.
If you want the scale of what’s converging on Confluence: Lovable raised at a $6.6B valuation in December and was reportedly in talks for $12B by June. Replit hit a $9B valuation in March. Gamma passed $100M ARR before any of this even shipped. None of that is Atlassian’s growth, but all of it is now one click away from a Confluence page.

3. Sync-o
Here’s where the ranking criteria matter: by install count, Sync-o is earlier-stage than almost everything else on this list. What earns it third place is the specific problem it goes after, and how few other apps (on this list or off it) are built for that problem at all.
Every app above generates something. Sync-o’s job starts after generation ends: when a Jira ticket linked to a Confluence page transitions to Done, it identifies which section of that page is now stale, drafts a surgical edit to just that section, not a full-page rewrite, and publishes it through Confluence’s own version history with a one-click revert. If the AI gets it wrong, you’re one click from the previous version, not stuck reconciling a diff by hand.
Three things worth knowing if you’re evaluating it:
- It published a Data Processing Addendum and a CSA CAIQ Lite self-assessment before launch, not after a customer asked for one. Infrastructure defaults to AWS Ireland with Google Vertex AI in Belgium, and non-EU processing only happens if you explicitly turn on Bring Your Own Model.
- As of this month, it reads the GitHub pull requests linked to a closed ticket and folds a “Technical Details” summary into the page update, so the documentation reflects what actually shipped in code, not just what the ticket description said.
- It’s Cloud-only. If you’re still on Data Center, this isn’t for you yet, and Sync-o doesn’t pretend otherwise on its own migration guidance.
4. Riffle (Operational Resilience)
Riffle maps the dependencies, vendors, and failure points behind a critical business process, then turns that map into an actual recovery plan inside Jira and Jira Service Management. It launched during Atlassian’s Team ’26 conference with a direct investment from Atlassian Ventures attached, which is a meaningfully stronger signal than a normal Marketplace debut. Venture arms don’t fund apps they think will disappear in six months.
It’s too new for install numbers to mean anything yet. The signal here is who’s backing it, not how many teams have it installed.
5. Tempo’s new Rovo agent lineup
Tempo isn’t new. Seven new Forge-embedded Rovo agents launched under one program in June are. Sprint Performance Assistant, Structure Formula Assistant, Timesheets Summary Analyzer, and four more, all shipped together under what Tempo is calling the “Maestro Program.” Tempo also picked up Atlassian’s Partner of the Year 2026 award for Cloud Transformation Apps in the same window.
What makes this worth including over a flashier newcomer: Tempo already has the install base and the enterprise trust that a brand-new vendor spends years building. When an incumbent with that kind of reach bets seven products on Rovo at once, it’s a read on where Atlassian’s own platform investment is heading, not just on Tempo.
6. Frank. (“Not Your Regular HR Solution”)
Frank. keeps HR profiles, org structure, and permission-aware documents inside Jira and Confluence, and it uses Rovo to answer HR questions and turn onboarding docs into actual tracked tasks. It took first place in the Business Teams category at Codegeist 2025, Atlassian’s annual hackathon (officially the “Atlassian Williams Racing Edition” this cycle, winners announced February 9, 2026), and it comes from Avisi Apps, a vendor with 25 years in the space rather than a first-time team riding a hackathon high.
The honest limitation: HR-in-Jira is a genuinely unusual pitch, and whether engineering-tool-first teams want their HR data living next to sprint boards is a real open question, not a settled one.

7. Released
Released turns a customer feedback inbox, a public roadmap, and Jira activity into AI-generated release notes and changelogs, and it’s carrying the Cloud Fortified badge with 899 installs, both independently verifiable on its live listing. That’s real, earned traction, not a launch-week number.
One claim worth a caveat: Released’s own listing states it won an Atlassian Partner of the Year award for Marketplace Collaboration. We could not independently confirm that specific award category through press coverage, so treat it as vendor-reported until you see it corroborated elsewhere.
8. ScriptRunner AI Migration Suite
Adaptavist added an AI chat agent for converting scripts and a natural-language “Behaviours Bot” to ScriptRunner, aimed squarely at the wave of Server and Data Center customers migrating to Cloud in 2026. ScriptRunner is one of the most-installed apps in Atlassian Marketplace history, so this isn’t a startup testing a theory. It’s an incumbent pointing existing infrastructure at the single biggest theme in the ecosystem this year.
9. Secure Notes for Jira
An indie build, and the other first-place Codegeist 2025 winner worth naming here: encrypted, expiring notes for sharing sensitive context, like credentials or incident details, directly inside a Jira issue. The encryption is client-side AES-256-GCM, meaning it’s genuinely zero-knowledge. Not even a site admin can decrypt a note they weren’t given the key to. The implementation is public on GitHub, which is unusual transparency for a Marketplace app and worth rewarding on its own.

10. Mermaid Chart for Confluence
The official app from the team behind Mermaid.js, the open-source diagramming library with 82,000 GitHub stars, now with AI-assisted diagram generation built in. It has 3,670 installs, the highest verified count of anything on this list outside GitHub Copilot for Jira. Sometimes the most-adopted new app in a category isn’t the flashiest one. It’s the one solving a problem (bad, unmaintained architecture diagrams) that every single engineering team already has.
How they compare
| App | Category | Traction signal | Best for |
|---|---|---|---|
| GitHub Copilot for Jira | Dev workflow | 1,725 installs, GA | Teams already on Copilot |
| Confluence AI partner agents | Content creation | 3 major AI vendors | Spec-to-prototype, notes-to-deck |
| Sync-o | Doc maintenance | Early-stage, EU-compliance-first | Regulated or audit-heavy teams |
| Riffle | Operational resilience | Atlassian Ventures backed | Business continuity planning |
| Tempo Rovo agents | PPM / reporting | Established vendor, 7 agents | Existing Tempo customers |
| Frank. | HR | Codegeist 2025 winner | Teams centralizing HR in Jira |
| Released | Release notes | 899 installs, Cloud Fortified | Customer-facing changelogs |
| ScriptRunner Migration Suite | Cloud migration | Established vendor (ScriptRunner) | Server/DC to Cloud moves |
| Secure Notes for Jira | Security | Codegeist 2025 winner | Sharing credentials in tickets |
| Mermaid Chart for Confluence | Diagramming | 3,670 installs | Architecture documentation |
Two categories are conspicuously thin this year: nothing genuinely new showed up for test management, and AI ticket triage is crowded with single-digit-install entrants that haven’t proven anything yet. If you’re building in either space, the ground is unusually open.
Common questions about new Atlassian apps in 2026
What’s the most significant new Atlassian app in 2026?
By verified traction, GitHub Copilot for Jira. It’s the only entry on this list with both a confirmed GA date and independent press coverage beyond the vendor’s own announcement. By strategic significance, the Confluence partner-agent rollout (Lovable, Replit, Gamma) is arguably bigger, since it reshapes what Confluence itself can do rather than adding one workflow.
Are Codegeist winners actually available to install, or just hackathon demos?
Both, depending on the app. Frank. and Secure Notes for Jira are already listed on the Marketplace with real (if early) install numbers. Some other 2025 category winners are further from public release; check the live listing before assuming a Codegeist win means production-ready today.
Is Sync-o only useful for regulated industries?
No. Its EU-residency and published compliance posture matter most to regulated and audit-heavy teams specifically, but the core function, keeping a Confluence page’s existing content accurate as the linked Jira work changes, is a generic problem that any engineering team with a runbook or an architecture doc runs into.
How is a “Free up to 10 users” tier different from a full free edition?
It’s a pricing configuration, not a separate product tier. Atlassian’s Marketplace supports pricing a paid app at $0 for sites under a user threshold, which surfaces the app under the Marketplace’s dedicated free-tier filter without the vendor building a stripped-down SKU. Several apps on this list, including Sync-o, use this model rather than a limited “free plan.”
The pattern across all ten is the same one Atlassian itself is betting on: agents that act, not just apps that display information. Whether that agent drafts a pull request, redesigns a Confluence page, or quietly fixes a stale runbook section nobody remembered to update, the apps earning genuine attention this year are the ones doing work on your behalf, not just surfacing more of it for you to do yourself.
