Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsChoose hosting by estimating how many products you will track, how often you will check them, how much price history you will retain, and how much downtime you can accept. A tracker usually needs three capabilities: a place to run its user-facing app, durable storage for products and price history, and a reliable way to schedule collection jobs. Some providers bundle these pieces; others charge for them separately. Without workload estimates, no specific plan can be called the right fit.
What a price tracker needs from hosting
Hosting a price tracker is not just a matter of serving web pages. The app has to save product records and historical prices, then run collection work on a schedule. Depending on the design, that work may run inside the app host, on a separate worker, or through an external collection service.

- App runtime: serves the site or API and handles user activity.
- Database: stores tracked products, current prices, price history, and related account or alert data. As history grows, storage and connection limits become important.
- Collection jobs: fetch prices from stores or APIs, handle failures, and avoid overlapping runs that could duplicate work or overload a source.
Compare the operational arrangement as well as the advertised monthly price. Heroku lists its application platform and managed data services separately, while PocketBase Cloud presents a bundled database, frontend, and backend plan. These are different architectures, not directly equivalent tiers. See Heroku’s pricing page and PocketBase Cloud’s pricing page.

Estimate the workload before choosing a tier
Write down realistic first-month and growth estimates. The aim is not to predict perfectly; it is to expose which plan limits could become bottlenecks and what you need to measure after launch.

Collection volume
Estimate tracked products multiplied by checks per product per day. For example, 200 products checked every six hours would mean up to 800 planned checks per day, before retries. That is a planning calculation, not a claim about the capacity of any provider or the number of requests a particular retailer permits.
Also estimate how long each run takes, how many jobs may overlap, and what happens after a failed check. A schedule that looks modest on paper can create peaks if a large batch runs at once. Confirm that the application host supports the background execution pattern you need, or plan for a separate worker or collection service.
Database growth
Estimate stored records from the number of products, the frequency of successful checks, and your retention period. A simple upper-bound model is: tracked products × successful checks per product per day × days retained. Actual storage also depends on how the app represents each observation, indexes, metadata, and whether old records are compressed or deleted. Check usable database storage and connection limits, and decide how you will export or archive history if the database approaches its limit.

Traffic and recovery needs
Estimate active users and peak simultaneous requests, not just monthly visitors. Check whether a plan meters API requests, imposes a rate or concurrency ceiling, or charges for usage beyond a base fee. Set an acceptable recovery time: how long can the app or collection pipeline be unavailable before missed updates become a serious problem? Review backup frequency, restore options, and the provider’s stated availability or downtime terms rather than assuming a low price includes a particular service level.

Compare the hosting arrangements
The examples below are vendor-published plan details accessed on 2026-10-03. Prices and limits can change; check the linked pages before committing. Their features measure different things, so the table is a starting point for questions, not an apples-to-apples performance ranking.
| Offering | Published price and capacity | What it illustrates |
|---|---|---|
| Heroku Postgres Essential-0 | $5/month; 1 GB disk; 20 connections | Managed database listed separately from the application platform. Heroku describes Essential plans as using shared RAM. The pricing page states a maximum downtime of four hours per month for Essential plans. |
| Heroku Postgres Essential-1 | $9/month; 10 GB disk; 20 connections | A separate database tier with more listed disk capacity but the same listed connection limit as Essential-0. |
| PocketBase Cloud Free | $0/month; 50 MB storage; 500 API requests per hour | Bundled frontend, backend, and database with SSL. The instance pauses after 30 days without API traffic. |
| PocketBase Cloud Starter | $10/month; 3 GB storage | Bundled hosting with unlimited API requests, continuous backup covering the previous seven days, GitHub auto-deploy, custom domain, SSL, and DDoS protection. The listed locations are Frankfurt, Strasbourg, Beauharnois, Hillsboro, and Singapore; the page describes them as a shared pool selected at deploy. |
| Parseium Starter | $49/month; 150,000 monthly credits; 10 fetch and 3 browser concurrency; 3 databases; 1 GB storage | A separate collection-service example. Parseium says credits meter live collection work; stored-data queries and parser dry-runs against stored HTML are free. |
| Parseium Pro | $99/month; 700,000 monthly credits; 30 fetch and 10 browser concurrency; 10 databases; 2 GB storage | A higher collection-service tier from the same vendor, with higher listed credits and concurrency than Starter. |
| Parseium Business | $299/month; 3,000,000 monthly credits; 150 fetch and 30 browser concurrency; 30 databases; 10 GB storage | A further tier in that vendor’s offering; it is not a general market benchmark or a recommendation for a tracker. |
Sources: Heroku, PocketBase Cloud, and Parseium, accessed 2026-10-03. The listed prices do not establish the total cost of a working tracker: a component-based setup may require separate app hosting, database, and job-running services. Compare the combined bill and operational effort for the architecture you intend to use.

Decide how collection jobs will run
Scheduled price checks are a separate hosting requirement from serving the app. Before choosing a plan, verify the job runner’s schedule granularity, maximum run time, concurrency, retry behavior, and safeguards against a new run starting before the previous one finishes. Also decide how missed checks are handled after an outage.

Use a prototype-to-growth path
For a prototype
A free or small plan can be useful while validating the app’s data model and collection schedule, provided its ceilings match the test. For example, PocketBase Cloud’s published Free plan has 50 MB storage and 500 API requests per hour, and pauses after 30 days without API traffic. That makes those limits and pause behavior part of the prototype design, not an assumption to discover after deployment.
As usage grows
Measure database storage, request volume, job duration, failed checks, peak concurrency, and restore needs. Upgrade or separate components when actual measurements approach a plan’s limits or when its recovery and backup arrangements no longer meet your requirements. If price history is valuable, test that you can restore a backup and export the records in a usable format before relying on the system.
