The short version
- Each has a real cost: Meltano the company behind Meltano wound down in December 2025 and the project was transferred to Matatika, a much smaller organisation, so roadmap velocity and the size of the maintenance team are now materially lower than the tool's reputation suggests.; Microsoft Power Automate free plan limited to 750 flow runs/month and standard connectors only; premium connectors require paid plans
- They diverge on capability: Meltano covers Singer plugin management, Microsoft Power Automate covers Automated flows.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Meltano
- The company behind Meltano wound down in December 2025 and the project was transferred to Matatika, a much smaller organisation, so roadmap velocity and the size of the maintenance team are now materially lower than the tool's reputation suggests.
- Singer connector quality varies enormously; a tap may be maintained, abandoned, or maintained only for the subset of endpoints its original author needed, and you will not know which until a schema change breaks a load at 3am.
- There is no managed hosting from the project itself, so someone on your team owns scheduling, secrets, retries, alerting and upgrades, which is real headcount that a per-row SaaS bill was buying for you.
- It is command-line and YAML first with no meaningful web interface, so analysts who are not comfortable in Git and a terminal cannot maintain pipelines themselves.
- Debugging spans three layers, the tap, Meltano itself and the target, and each has its own logging conventions, so failures often require reading Python source in a third-party connector.
Microsoft Power Automate
- Free plan limited to 750 flow runs/month and standard connectors only; premium connectors require paid plans
- Not suitable for long-running workflows; can fail unexpectedly without warning
- Limited to simple linear logic; fails with complex workflows involving multiple stakeholders
- Tasks cannot automate at scale when requiring more than approximately 60 users

Answered from the vendors’ own pages
Meltano: Is Meltano still maintained after the company shut down?
Yes. Arch, formerly Meltano, was acquired by Matatika in December 2025 and the open source project continues under their stewardship, with releases through 2026.
Microsoft Power Automate: Is Power Automate included with Microsoft 365?
Yes. If you have an eligible Microsoft 365 subscription, you can use Power Automate at no extra cost for flows relying only on standard connectors (SharePoint, Outlook, Teams). Premium connectors (Salesforce, SAP, Oracle) require paid plans.
SourceMeltano: Is there a hosted Meltano?
Not from the project. Meltano Cloud was retired, and hosting now comes from Matatika or from running the container yourself.
Microsoft Power Automate: How many flow runs are allowed on the free plan?
Power Automate's free tier (included with Microsoft 365) is limited to 750 flow runs per month and standard connectors only. Out of 900+ total connectors, the free plan only includes Microsoft ecosystem apps and limited third-party apps.
SourceMeltano: How does it compare on cost with Fivetran?
Meltano has no licence fee, so the comparison is your engineering time versus Fivetran's per-monthly-active-row billing. High-volume, low-complexity sources favour Meltano; long tails of fiddly SaaS APIs favour Fivetran.
Microsoft Power Automate: What's the difference between Premium and Process plans?
Premium ($15/user/month) provides attended automation with cloud flows and standard RPA. Process plan ($150/bot/month) enables unattended automation where bots run without human intervention on virtual machines for high-volume, repetitive tasks.
SourceMeltano: Can I use Airbyte connectors with it?
Yes, Meltano can run Airbyte source connectors through a bridge, which widens the connector pool beyond Singer taps.
Microsoft Power Automate: Does Power Automate support long-running workflows?
No. Power Automate is not suitable for long-lasting workflows because they can run without warning and fail unexpectedly. The platform is built for linear, branching logic (if-then) rather than complex, multi-step business processes involving multiple stakeholders.
