# Apache Projects for Small Business: Full Catalog

Published October 30, 2026. Research snapshot: October 29, 2026.

[Read the Apache projects for small business guide](https://jwatte.com/blog/apache-open-source-projects-small-business/).

## How to use this catalog

Find a business problem in the group headings, or search this document for a project name. Follow a group's link for examples, costs and advice on whether the software fits your business. Each project name links to its official homepage; a linked version points to the evidence used for that release. Ask whoever maintains your systems to check current support and security notices before selecting a version. We read the sources listed here but have not installed these projects for this series.

**You** means a capable owner or helper can run the useful desktop or single server case. **IT** means your IT department or provider should plan and operate it. **Developer** means a library, development tool or contributor resource you usually encounter through someone else's software. These are our suitability judgments, not ASF certifications. A simple installer does not remove the work of access control, updates and recovery.

There are **327 entries: 303 established entries and 24 incubating projects**. Only seven are in the You tier; 111 need IT and 209 belong to a developer's work. Entries include components and community resources, so this is not a list of 327 independent applications. Projects marked **(Incubating)** are still working through Apache's entry process and are not yet fully endorsed by the ASF; see the [Incubator disclaimer](https://incubator.apache.org/guides/branding.html#disclaimers).

Read the release column as the latest dated evidence selected for this snapshot. **Registry date** can be stale. **File date** is a distribution artifact's modification date, not a separately verified release announcement. A preview or milestone is not a stable release. **Not listed** means the checked sources did not establish a release version and date; it does not prove there has never been a release. Some umbrella projects release components independently, which the notes explain. Four dormant Commons entries, three inactive Logging entries and the end of life Commons HttpClient remain in the directory and retain warnings here.

<!-- CATALOG TABLES END -->

## Count rule and date

The [Apache project directory](https://projects.apache.org/projects.html) merges the [project registry](https://projects.apache.org/json/foundation/projects.json) and the [podling registry](https://projects.apache.org/json/foundation/podlings.json), using the project registry when an ID appears in both. The union contains 403 entries. We removed 70 records already labeled retired and six more entries with explicit official retirement evidence. That leaves 327 distinct directory IDs, with each assigned to exactly one of the 16 groups above. The tables contain each ID once, with no omissions or duplicates. Directory membership alone does not establish active maintenance, production readiness or suitability for your business.

The six additional exclusions are IvyDE, the .NET Ant Library, the VSS Ant Library, Annotator, Woden and Derby. Their official sources are the [IvyDE status page](https://ant.apache.org/ivy/ivyde/), [retired Ant libraries](https://ant.apache.org/antlibs/retired.html), [podling history](https://projects.apache.org/json/foundation/podlings-history.json), [Woden homepage](https://ws.apache.org/woden/) and [Derby homepage](https://db.apache.org/derby/). The registry snapshots were read on October 29, 2026 at 21:00 UTC.

The companion articles use the following common inputs, read October 29, 2026. Prices are US dollars before tax. Monthly server prices are full month caps without introductory credits or annual discounts. These figures are planning inputs, not a managed IT quote.

October 30, 2026 update: our AI assisted scenarios keep hosting and backups unchanged, include human review in assumed labor hours, and add subscription allocations or metered API charges. These are planning assumptions, not measured Apache installation times. The worksheet below repeats the hub's Answer example.

| Input | Value and scope | Public source |
|---|---|---|
| Server administration labor | $68.09 per hour: $47.66 median hourly wage divided by a 0.700 wages share of compensation | [BLS systems administrator profile](https://data.bls.gov/oesprofile/?areas=INDUSTRY,STATE,MSA&major_group=150000&measure=01&occupation=151244&year=2025), [BLS compensation share](https://data.bls.gov/timeseries/CMU2020000000000P) |
| User support labor | $42.49 per hour: $29.74 divided by 0.700; only for work that fits user support | [BLS support specialist profile](https://data.bls.gov/oesprofile/?areas=INDUSTRY,STATE,MSA&major_group=150000&measure=01&occupation=151232&year=2025) |
| Small server | DigitalOcean Basic Regular, NYC3, 2 shared vCPUs, 4 GiB RAM, 80 GiB disk: $24 per month | [DigitalOcean prices](https://www.digitalocean.com/pricing/droplets) |
| Medium server | DigitalOcean Basic Regular, NYC3, 4 shared vCPUs, 8 GiB RAM, 160 GiB disk: $48 per month | [DigitalOcean prices](https://www.digitalocean.com/pricing/droplets) |
| Large server | DigitalOcean General Purpose Regular, NYC3, 8 dedicated vCPUs, 32 GiB RAM, 100 GiB disk: $252 per month | [DigitalOcean prices](https://www.digitalocean.com/pricing/droplets) |
| Off site backup storage | Backblaze B2: $6.95 per decimal TB per month; first 10 GB free | [Backblaze B2 pricing](https://www.backblaze.com/cloud-storage/pricing) |
| Backup usage | Egress above three times average monthly stored data costs $0.01 per GB, unless a qualifying partner exemption applies; [Class D calls](https://www.backblaze.com/cloud-storage/transaction-pricing) cost $0.004 per 10,000 after the first 2,500 per day | [Backblaze B2 pricing](https://www.backblaze.com/cloud-storage/pricing) |
| One server, You tier | Our assumption: 4 to 12 setup hours and 1 to 3 administration hours each month | Editorial planning range |
| Small cluster with IT oversight | Our assumption: 24 to 60 setup hours and 6 to 16 administration hours each month | Editorial planning range |

Choose the server after checking the project's requirements. Multiply hosting by the node count. Storage cost is max(0, stored GB minus 10) x $0.00695 per month; count all retained backup versions. A backup also needs a tested restore. Network overages, extra disks, paid support and other services need their own prices. The labor rate estimates employee compensation; an outside provider's billable rate can be higher, so get a quote.

Setup cost = setup hours x hourly labor rate. Monthly cost = hosting + backups and usage + monthly administration hours x hourly labor rate. Self hosted cost over 36 months = setup cost + 36 x monthly cost. Alternative cost over 36 months = alternative setup + 36 x its verified monthly price. Savings = alternative cost minus self hosted cost; a negative value means self hosting costs more. Use both ends of the labor ranges and state user counts, storage and node assumptions. These ranges exclude custom development, a major migration, training, compliance assessments, on call coverage and serious incidents.

If self hosted monthly cost is lower, break even month = ceiling((self hosted setup minus alternative setup) / (alternative monthly cost minus self hosted monthly cost)), with a minimum of zero. If it has equal or higher monthly cost and no setup advantage, break even is never. When its initial advantage later disappears, state when that happens. Do not treat an owner's unpaid time as free.

### Cost worksheet: Answer with AI assistance

See the [hub's setup time comparison](https://jwatte.com/blog/apache-open-source-projects-small-business/#setup-time-when-claude-or-chatgpt-does-the-typing) for tool roles, guardrails and the full discussion.

Our example is a ten person print shop with two moderators, one $24 monthly DigitalOcean server and 50 GB low or 100 GB high of retained Backblaze B2 backups. We assume no chargeable transfer or requests and an otherwise unused 10 GB free allowance. Discourse Pro is $100 monthly, or $3,600 over 36 months, with zero additional technical setup or administration assumed. Moderation, content, migrations, training and incidents remain outside both comparisons. The server is a planning allowance, not an Answer hardware requirement.

| Answer planning input or 36 month total | Low case | High case |
|---|---:|---:|
| Manual setup hours | 4 | 12 |
| AI assisted setup hours | 2 | 9.6 |
| Manual monthly admin hours | 1 | 3 |
| AI assisted monthly admin hours | 0.75 | 3 |
| Manual total | $3,598 | $9,057 |
| Claude Pro subscription total | $3,049 | $9,094 |
| ChatGPT Plus subscription total | $3,049 | $9,094 |
| API total: Claude Opus 5.5 | $2,863 | $9,008 |
| API total: GPT-6 Astra | $2,886 | $9,179 |
| Discourse Pro total | $3,600 | $3,600 |

Use `manual = S x L + 36 x (H + A x L)` and `AI = S x q x L + T0 + 36 x (H + A x r x L + Tm)`. Here S/A are manual setup/monthly hours, q/r their retained shares, L is $68.09, H is hosting plus backups, and T0/Tm are setup/monthly tools. Round only final totals.

For your own worksheet, enter S = ___ hours, A = ___ hours, q = ___, r = ___, L = $___, H = $___ monthly, T0 = $___ and Tm = $___ monthly. Keep the manual case. Our low/high shares are 50%/80% for setup and 75%/100% for monthly administration. Prompting, supervision, testing and corrections are included; setup review of 1/3 hours and monthly review of 0.5/1.5 hours are already inside the AI hours, not extra charges.

Claude Pro and ChatGPT Plus each use a $20 setup month followed by $5 monthly for 36 operating months. That 25% allocation is justified only when other work uses the remaining subscription. With no other use, add $540: totals become $3,589 low and $9,634 high. Do not allocate more than the full subscription across projects. Check usage allowances and price extra usage; equal prices do not mean equal capacity. Optional Desktop Commander Remote Pro at $20 monthly adds $200 using the same allocation. The base uses free local tooling, with hosting and model charges separate.

Our assumed cumulative API budgets are 200,000/1,000,000 input and 20,000/100,000 output tokens for setup, then 100,000/500,000 input and 10,000/50,000 output monthly. Low input is 30% ordinary, 10% short cache writes and 60% reads; high input is entirely ordinary, with caching disabled. Budgets include repeated context, retries and billed reasoning. They sum multiple calls, each within the applicable context band; no cache reuse between months is assumed.

API tool cost = (ordinary input x input rate + cache writes x write rate + cache reads x read rate + output x output rate) / 1,000,000. Per million tokens, ordinary input/output/short write/read rates are $4/$20/$5/$0.20 for Claude Opus 5.5 and $10/$50/$12.50/$1 for GPT-6 Astra. We use standard synchronous rates without batch discounts or conditional credits. This gives T0/Tm of $0.764/$0.382 low and $6/$3 high for Opus; $1.97/$0.985 low and $15/$7.50 high for Astra.

For example, low subscription cost is `2 x 68.09 + 20 + 36 x (24 + 40 x 0.00695 + 0.75 x 68.09 + 5) = 3048.618`. High subscription cost is `9.6 x 68.09 + 20 + 36 x (24 + 90 x 0.00695 + 3 x 68.09 + 5) = 9093.902`. Replace T0 and Tm with the token charges for either API view. The original manual results before rounding are $3,597.608 and $9,057.318.

The low conclusion changes to modest savings against Discourse: subscriptions break even in month 8 and APIs in month 6. All high cases still lose. In the high case, subscriptions become more expensive than manual Answer operation in month 29; Opus does so in month 53 and Astra in month 20. With the full subscription assigned to Answer, the low case saves only $11 against Discourse over 36 months.

Use a new server, keep secrets out of chat, and approve commands or use a restricted sandbox. Watch browser actions, review configuration and test an Answer restore before real users depend on it. Subscriptions cover people directing supported tools; use API keys for custom automated pipelines and check the applicable terms. We still own permissions, backups and updates.
